>> Good afternoon, everyone.  Please welcome Derrick Nehrenberg for the last presentation of the evening.
      [Applause]
      >> Can everybody hear me okay?  We've almost made it.  Last talk of the day.
      So I don't have any grand solutions or super slick technology to show you today, but I do think I have an interesting story to share with you.  And I'm going to try to tell the story by a few different ideas.
      So I have a mountain biking problem.  I love mountain biking and big mountain -- big mountain loops in the back country.  I love going on road trips with my buddies doing mountain bike vacations.  A few years ago I went on a mountain bike vacation with three of my friends in Durango, Colorado.  And what we wanted to do for our last big ride was ride from the Purgatory resort and ride over to the Colorado trail and then take the Colorado trail down into Durango.  And the problem that we had was we couldn't find any maps of the trails connecting the backside of the Purgatory resort to the Colorado trail.
      So we ended up running into this guy who knew the local trails, and he had a piece of receipt paper in his truck and a pen, and he drew us a map and added some information to it.  So we headed off with that Pete of receipt paper into back country.  And of course we ran into problems.  We got to a fork in the trail and one of the -- at the fork, one trail went down one drainage, the other trail went down another drainage.  And so we had 50/50 chance, we decided to take it.  Long story short, we went down the wrong drainage.  So we ended up spending the night, a 35-degree night out at 10,500 feet with no fire, no clothes, no food, no water.  And so we ended up spooning together.  We did.  We were spooning together, my spooning partner was nicknamed the filth.  That was his real nickname.  And I can tell you that he came by that nickname honestly.  And so I don't know whether it was his fumes or the hypothermia that we all experienced, but I had a vision that night.  The vision of the ultimate solution to our predicament.
      This was really the Eureka moment for JuicyTrails, and I thought, well, this -- people probably run into this problem, we wouldn't run into this problem if there were trail signs that had a map on them and better yet wouldn't it be great if those trail signs had map codes that you could use to download that map onto your phone?  And then follow it when you're out in the back country?
      So that was really the Eureka idea that led to JuicyTrails.  And the basic idea behind JuicyTrails are really simple.  The first idea was that I figured if I wanted it, other people probably wanted it too.  And the thing that I want most out of a trail map app is -- and the thing that's most important to me and my safety and also to the fun factor is for the trail coverage to be comprehensive and accurate.  That is the most important thing.  And the second idea is that in order to create a comprehensive trail map on a large-scale for like the areas that I like to visit, I realize that it would require a collaborative community effort to build those kinds of maps and so I really think it's best that those kinds of maps are built with open data.  It's the only way, I think, to produce collaborative projects necessary to create comprehensive maps.
      So I live in Crested Butte, Colorado, it's a special place, in the middle of the state at the end of a road and surrounded by national forest and wilderness areas, also surround by hundreds and hundreds of miles of trails.  In my opinion, the best mountain biking trails on earth, that's why I live there.
      And so -- I forget what my next slide is.  So until recently, around Crested Butte, there were hardly any trails signs on all of these hundreds of miles of trails and also really no great maps that were comprehensive and completely accurate.  And this is causing a lot of problems for people to visit crescent view.  Also people who live there.  So, for example, there's a lot of -- there were and still to some level are a lot of user conflicts.  You know, motorcyclists riding on mountain bike trails, mountain bikers on hiking trails, and it was also there's been a lot of trespassing issues, the ranchers are concerned about people wondering onto their private lands, leaving gates open, cattle getting out.  And also people get lost, which is a real problem.  People die in our area of the country just last week a lady hiked up mountain crescent, went off the trail a little bit, not exactly sure why, but she fell 150 feet to her death.  And this is last week.  And last year a lady died out in the back country, and they presumably think because she was following an inaccurate map.  They found her eight months later.
      So the community had to do something about this and the forest service didn't have the money to do anything about the trail sign problem so the tourism association decided they would foot the bill for trail signage initiative.  And so the problem was that all the trail -- all the necessary data to build a comprehensive trail map was in different people's pots and these pots didn't share very nicely with each other.  And so like the forest service had some data, the town of crescent Butte had some, even the trail association had pots of data, but they couldn't figure out how to collaborate with each other.  So I made a suggestion why don't we build a map using OpenStreetMaps?  Oh, one point that I wanted to make here is that the selling point for building the map with OpenStreetMap was that I told them that not only will you get accurate trail data out of it, everybody else in the world using OpenStreetMap to build their mobile trail maps will also have great data for their maps.
      So we use the JuicyTrails platform, and we built the Crescent Butte trails Web application, and I had mentioned this before, but the JuicyTrails application and the CBG trails app, it's a single platform that serves on the back end as a mapping platform and on the front-end as a mobile trail map app.  So you can map trails, you can create routes, you can add them to mobile maps that work offline, and then you can create and share websites and also share all of that content on social media.
      So the very first task of course was to build a trail map.  And so we used OSM ID editor, customized just a little bit for JuicyTrails.  So it includes all the standard features you might be familiar with.  And also the JuicyTrails map style and the heat map and slide tool.
      So I'm sure most of you are probably already familiar with the Strava heat map.  What it does is collect GPS data from its users and makes it available as a open resource so people can use it to map stuff like trails.  In my opinion, it's the best thing that has happened to trail mapping ever, other than OpenStreetMap itself, it's wonderful.  I hope Strava keeps it going.
      So here we're looking at Bing satellite imagery, Strava heat map, I'll just give you.  You guys know how mapping works, but I'm going to play this real quick.  So you can draw a vector line, roughly trace it in, use a line to the heat map, and you just tag it the path, give it a name, you guys know how it works, bicycle equals yes and give it a commit message and JuicyTrails server picks it up and shows it in the map.  You guys are probably all really familiar with that.
      But it -- we're not going to get into that.  I don't have time.
      So one small thing that makes JuicyTrails unique is that -- and I'll show you this in a minute.  Is that the JuicyTrails uses line colors to illustrate which activities are permitted on a given trail.  So, for example, how a path equals a redline, if you give it -- a path can either be a paved trail or unpaved trail so if you add a surface path, it's a magenta line, if you add horse equals yes, it gives you a purple line.  So on and so fourth.  Really simple stuff.
      So we did this, and we worked with all the community state holders forest service, the trail associations, and the town of Crested Butte and mapped it together.  We followed a very simple strategy I'll share with you.  So first thing we decided to go was map everything highway equals path.  So after we did that be with we worked collectively to add the appropriate tags to the map and, again, this is not rocket science.  But in the end, what you would get is one multiuser map.  And at the end of the pipe this is what it looks like.  This is just a quarter of the trails in Crested Butte.  So the green trails and motorcycle trails, dark orange trails are hiking of course and bike trails.  The purple ones are hiking only trails.
      So, in addition to creating mobile map, we're also making the trail signs also available with OpenStreetMap data.  And these trail signs are going up all over the forest at every major trail intersection.  It's a huge project.  And the trail signs have map download codes on them so when you walk up to a sign, you can load the map onto your phone, and it works offline.  And also making a kiosk that are going up everywhere.  And visitors love this.  This has been a huge hit because auto F you've never been to Crested Butte before, you can look at a big map, download it to your phone and go out to the back country with greater confidence; right?  You could probably also have more fun.  People really like this a lot because not only does it give them more confidence, I think that it enhances their user experience quite a bit.  Practice have so the trail associations are using CBG mapping beds and putting them on their websites so they can tell their users where to go.  So this is trails example of a mapping bed and the Crested Butte mapping is biking association is in the middle of developing a new website, they're taking a step further and creating recommended rides.  There's 33 recommended rides.  I mean you can do two just by going to their website and if you look at the website, mobile device, you can download that map and follow it right to your phone right from the website.
      So it has been a huge hit.  Everyone from the executive director of the mountain bike association to the director of community in economic development Gunnison county and the director of Crested Butte tourism association.  Everyone has little different reasons why they like it.  The Crested Butte tourism association uses it as a marketing vehicle to increase trail user visitations, tourism to the valley, many also they use it as a way to enhance people's experience once they got there.
      So, in addition to, like, the CBD trails app being, you know, pretty successful, the data itself is somewhat of a small success, and it has provided a lot of benefits that we didn't even really anticipate.  So this is Hilary Henry, she was the director of the public lands initiative, and she gave me a call one day and said, these creating a master plan for the public lands in the area, they went to take it to congress.  They need a trail data for their master plan.  She was having a really hard time finding the data because nobody had all the data in one pot.  And she was, like, Derrick, can you somehow share the data with me?  Can you mash a button?  Go to geo fabric, go to Colorado shave file and there's all you need.  Very quickly she was able to pull down all the data and put it in her master plan.  It makes a big difference, it makes her plans a whole lot better.
      So we thought this was, you know, we finished CBD trails project the first wave of it.  We're still into it.  We finished first wave of it last August.  We thought, well, we could start serving more of these projects.  Sort of thought we were off to the races.  So I ended up having a lot of conversations with different kinds of organizations from communities to counties to the state of Colorado to the Federal Government.  And all of the conversations went about exactly the same way, and you guys might suspect how the conversations went.
      So one of the conversations I had sort of illustrates all of them, I had a really great conversation with the director of the Colorado parks and wildlife office, the GIS director.  And he was charged by governor Hickenlooper to create an interactive map of trails of Colorado.  So it was a great idea, it's a really great idea.  I really admired the decision a lot.  But what someone was talking to about the Colorado parks and wildlife director, I was telling them how are they doing it?  And what they're doing is they're calling every community, every land manager in the community, and they're manually sending them their data so that they can build a closed database so that they can produce this interactive map.  And I said, well, what's your ultimate goal?
      And he said, well, ultimately when we're done, we want to make it available to the public.  And I was, like, well, there might be an easier way.  Have you thought about using OpenStreetMaps?  And he said, well, no -- well, actually, yes, but we can't do it.  And I said why is that?  And he said because we're afraid of road trail mapping.  And that's the answer almost every community gives.  They will not adopt OpenStreetMap because they fear road trail mapping.  And no amount of talking I can do can convince them that that is largely, not always, but largely a myth.  Because if you care about secret trails, if you're a person who cares about secret trails, the last thing you want to do is publish your secret trail in OpenStreetMaps and make it available for the world to see.
      So I'm going to backpedal here real quick.  I've got just a few more minutes.
      So in my former life, I was a neuroscientist geneticist.  I went into the basic research because I wanted to do something for the public good; right?  And through my own research and to the research of others, it became obvious to me, may not be obvious to everyone, that we would never create a pill that's more effective at improving human physical and mental health as exercise in the outdoors.  And recent research is bearing this to be true.  Exercise in the outdoors enhances new hormonal growth in the campus.  Activity is linked to spontaneous brain activity associated with improved cognition.  And this is a real interesting article.  Major -- simply the act of being out in nature for a period of time has a positive effect on a person's mood over and above exercise alone.  So clearly that's a great way -- two minutes.
      All right.  So -- yes.  I wasn't going to share this story, but I'll share it with you.  Before graduate school, I worked in a bike shop, and we built a bunch of secret trails in the Carolina north forest.  And -- let's see.  Short way to tell this story.  So the University of North Carolina planned to build a north campus in its forest, and we tried our hardest to keep the trail secret but when Carolina went to public hearings to show the town members its plan, droves of people showed up and protest.  Almost shut the operation down, and they were really upset because the university was going to build trails in the forest and, you know, effectively ruining the forest.  So the basic lesson that I draw from this is that when users use trails with guess what happens?  You get more trails.  And you see that and you hear that from many stories all across the country.
      And so the idea that wraps this together is that, you know, not -- the good trail maps feed into this loop of users using trails and users use trails, you get more trails because I believe that better trail maps, more accurate trail maps will give people greater confidence to get in the outdoors and use trails more.  And when they use trails more, you get more trails.  So I think good maps have a role there.  So a few weeks ago, I got really frustrated and made a perhaps rash decision.  We decided to split our company.  We are instead of trying to ask and ask if we can help communities make trail maps, we decided we would return JuicyTrails into GoMaps.  JuicyTrails is going to become its own standalone app and our goal is to help comprehensively map all the trails in the U.S.
      If you look at the state of trail mapping in the U.S., it's pretty easy to see the state when you look at the JuicyTrails map.  Trail mapping has progressed rapidly in the last several years.  Already OpenStreetMap data allows you to build the most comprehensive maps in many areas the country.  It's really astounding how quickly it's growing.
      And so, you know, I don't have a solution or sweet piece of technology that's going to, you know, allow me to wave a magic wand and make all of this happen.  But I think it is very possible for us as a community to get from the state where trail mapping is now to a point where all the trails in the U.S. are comprehensively mapped.  I don't know exactly how to do it.  I have some ideas.  But I do know from my experience that the only way that we're going to be able to do it -- and of course, you know, I'm going to reset the volume here.  The only way we're going to be able to do it effectively on a large-scale is if we collaborate as a community with OpenStreetMaps.  That's it.  Thank you.
      [Applause]
      >> Thank you, Derrick.  We have a couple of minutes for questions.
      >> Nice job.  GoMaps.  You know there's GoMap.
      >> It's GoMaps.U.S.  It wasn't I that made that decision, it was developer probably in the middle of the night when he was working.
      >> Yeah.  So just be aware that that's the most popular editor for OpenStreetMap.
      >> Yeah.  I met the developer for that and that is a great app.
      >> Okay.  But keep at it.
      >> Okay.
      >> GoMaps is a third party app developer.  It's not going to be a standalone app.
      >> Okay.
      >> Before I take the next question, I'm just going to let you all know that the closing session starts at 5:30 in this room.  So just stay here.
      >> I have a question.  I'm a park employee so go to the park looking for a bike key if you look, if a key automatically to get back.  In database, easier to get, geocoding and --
      >> Geocoding and accuracy.
      >> I'm sorry.
      >> Geocoding will help.
      >> So you're saying you think geocoding will help in the accuracy of the maps?
      >> Yeah.
      >> I would agree with that.  I'm sorry.  I'll talk with you more afterwards.  Okay?  Sorry about that.
      >> Yeah.  I was just wondering if you take cell phone coverage into account on the bar codes on the maps that are out on the trail.
      >> Yeah.  But, you know, we tried a while back, not with this project.  Use bar codes, QR codes.  But that's not a reliable method.  So we just have people type in a text code into the app.
      >> Okay.  I guess what I'm wondering is if there were halfway up the map and all of a sudden there's no self coverage, and you've got a thing you're typing in, it's not going to help you much.
      >> Well, that's --
      >> Or, you know --
      >> That's true.
      >> Or maybe recommendation to do it at the trailhead or something.
      >> Yes.  You do have to have Internet connection to download the map.  But when downloaded, they work offline.
      >> Which is great.  Just maybe give people a heads-up on the Web page when they're looking for your maps.
      >> Okay.  That's a great idea.  Thank you.
      >> Hi, friends so I'm a mountain biker and pretty bad hiker but this would be super helpful for me.  I was curious about the cross contrast in local sources.  Is there a way you could view a trail and throw it out if it's inaccurate?
      >> That's a good question.  The level of accuracy I, you know, it's determined by the heat map really because we align all of our trail data to the heat map, in most cases.  And I found that to be the most accurate way to geo-reference trails.  It's far superior to other things that I've tried.  Does that make sense?
      >> Absolutely.  Thank you.
      >> Any other questions?
      >> So I'm also an avid user to mountain bike trails.  Here in Washington we have some really dense areas so there's like -- it's a two acre plot that has, like, ten trails that get super tight.
      >> Uh-huh.
      >> Do you have any recommendations for how to tease that out?  Because on the heat map it basically looks like a blue blob.
      >> Yeah.  You know, in those kinds of situations, it's better if you have individual GPS tracker that you can reference.  And there's ways to, you know, get those of course the best way is to go collect it yourself.  Yeah.
      >> And more fun.
      >> Yeah.  All right.  Is that it?  Thank you very much.  Oh, there's one more question?
      >> Have you worked -- have you worked at all at mapping winter recreation where, like, for instance, that has trails out during the summer but mountain biking and some of the skiing in winter?
      >> Yeah.  We've tinkered with it.  We haven't conducted a real project trying to do that yet.  But there's 55 kilometers of Nordic trails around Crested Butte and skiing is off the chain.  And we've tinkered with it and that's all in the OpenStreetMap database.
      >> Well, please provide Derrick with a warm thank you.
      [Applause]
      >> Welcome, everybody.
      So did everybody have a great time?
      [Applause]
      You want to do this next year?  Yeah, somebody has to put a proposal in.  So start thinking about it.  We had a great time doing this, so if you want to do it you'll get all the help from me.
      This is it.  First of all, I would love to thank our sponsors.  We couldn't have done this without our sponsors, especially I'll list the gold sponsors so we don't go through a whole lot.  But Craigslist, Google surprisingly.  I mean Google has been a great sponsor over the years, Mapzen, Mapbox, and Telenav.  So let's give them all a great thanks.
      [Applause]
      I would also like to thank our board.  The U.S. chapter board works really hard.  I'm on the board, and I want to tell you I've been under conference calls.  They normally have to deal with putting on this conference but then after -- they have to go to their conference call to deal with the board matter.  So it's an unpaid position, it's a lot of hard work.  So I want to thank.  We have Alex here, Alyssa, are you here?  Drishtie.  March tine.
      >> And Ian.
      >> And Ian who is away on vacation in Europe.  So and Ian for being on vacation, he has taken care of so many billing things, paying people, that I just can't believe.  He was actually booking reservations for us from Europe, so we could make sure this conference went on without a hitch.  So thank you very much, board.  Keep up the great work.
      [Applause]
      And I can't go without thanking the local organizing team.  They put up with me through a lot of pain, but we had a great time.  I'll start with Chase Stevens, but Chase and I have been working together for years.  He's a great partner to work with.  And really contributed a lot.  As well as -- is Arie still here?  So Arie is the one that did the tableau presentation today that was coming doing in two weeks.  And, Joel, Joel are you here?
      >> I think he's still wrapping up with the volunteers.
      >> He's still working.  So Joel did all the volunteer work.  And I want to tell you I want to actually mention the volunteers.  The volunteers we have this year were absolutely awesome.
      [Applause]
      I'm serious.  They ran, they hustled.  I couldn't run up and down the halls like you did.  I'm impressed.
      There's also Phoebe, Phoebe are you still here?
      >> She left.
      >> She left.  So Phoebe was the one that put on the geo ladies event.  So thank you very much, Phoebe.
      [Applause]
      And there's somebody else that you probably didn't think of but Peter, I don't know if Peter's still here or not.  Peter is the one that got the beer and the wine for the party last night.  So, yeah, thank you, Peter.
      [Applause]
      So this is pretty much wraps it up.  I want to tell you.  We didn't plan for any special thing.  There are so many interesting things to do in Seattle that I hope you get a chance to go out and see some of them.  I'm going to mention a few of them.  The museum of flight, which is closed now.  But if you have some time tomorrow, the Museum of Flight is not too far from here.  Fantastic museum.  There's the museum of glass in Tacoma.  I'm a glass galore, you can watch them make beautiful glass down there.
      Go to Seattle center.  There's a lot of fun things to do there.  There's of course the Space Needle, the EMP, the experienced music project if you like music.  It's an ugly building, but it's a really --
      [Laughter]
      Paul is going to kill me to saying that.  The science center is located to.  If you like really things.  Pikes place market is a great place.  They throw fish there.  They really do.  They have great food there plus shops.  Pacific Pines Park, it's right around, the water I believe.  It's a great place.  If you're looking for something really kind of unique, Starbucks has a reserve -- Starbucks reserve is located on Capitol Hill not too far from here, and it is you can do coffee casings, and actually beer and wine too.  It's packed all the time.  It's a great place to go.  And there are a group of people planning a party at golden gardens tonight at 7:30.  Golden gardens is a social area, a gorgeous park right on the water, it's sandy, you can see some great ships going by, if you see any baby seals, please leave them alone, they're okay.  If you see any eagles, stay out of their way, they're hungry.  But that's it, folks.  I want to thank you very much.  I've had a great time.  I hope you all did too.
      [Applause]
      >> Just a few more minutes.  Isn't it an amazingly put together conference?
      [Applause]
      I'm super had you heard by it.  I'm hoping we can do just as good of job.  My name is Martijn, I tweeted out before this conference that I was bringing two things, and I didn't want to leave with me of.  So one time of things is all the old street maps you've seen at the table up there that was OSM U.S. foundation table.  So if you haven't taken one yet, look for your favorite state or city and take one of those maps, they're free for you to take more than one if you want.  And the other thing is these vests.  I've got a lot of comments on them.  A lot of people seem to want them, and I only have seven.  So what I'm going to do is anyone here who has never organized a mapping party or local mapping event and pledge to do so before the end of the summer can come collect one right now from me.  If you do so in your -- you're not quite sure yet, and I still have some left, send me a picture, and I'll send one to you.  So that's that.  If you want to come up right now, that's okay.  If you've never done a mapping party, it's easy and fun to get some local folks together.  Who of you have never been to a local mapping party?  It's almost half of you.  That's way too many.
      [Applause]
      Sorry.  I don't want to be judgmental.  But it's just a lot of fun.  But there's a question even.  I didn't count on that.
      >> What is a mapping party.
      >> Yeah, sure.  I'm making a lot of assumptions.  I'm so sorry.  So mapping party can be two things in my mind, correct me if I'm wrong more experienced mapping party organizers.  It can be two things.  Number one you sit down in a room, and you get together and do, for example, Missing Maps or remote mapping.  Or that's what these are really for, you go out and map.  You go out on the street, you find an area that's poorly mapped either businesses or addresses or whatever your fancy and if you wear these, you'll look official so they don't -- they might help in places where people are maybe not as friendly.  People are friendly everywhere.
      Really what I'm saying is just go ahead and get some people together in your area.  Also if you're not a member of OSM U.S. or OSM foundation yet, please consider doing that and supporting making this possible.  Not only our sponsors but also our members make this possible.  So I really appreciate and anyone else in the U.S. appreciates your continued support.  It's been really great having you all the members who already are and hopefully we're going to welcome some more.  That's all I'm going to say.  Thank you very much.
      >> If anybody has announcements, feel free or any other activities.
      >> Tomorrow.
      >> Tomorrow is a workshop day, so I encourage you to come back, get your hands dirty if there were other that you would like, hack-athons, please come back to this building.  I would so recommend the underground tour and thank Clifford for all of his help and the local organizers as well.  You've been amazing.
      Is there any other announcements?
