00:01One element of this content is something I’d like to share called a Community Basemap.
00:06Some of you have heard of it, some of you have seen the beautiful maps on the walls as you’ve come in this morning.
00:10I’m gonna show a brief video and then we’re gonna actually look at it in greater detail.
00:25Every organization is investing a lot of time and energy into combining data for their areas of interest.
00:34If we can combine our respective information into a harmonized, continuous map of the world...
00:43...into a map that works at all kinds of scales, the global level, at a national level, at a regional level...
00:51...and even down to the block level and perhaps even into a building.
00:56The goal of the Community Basemap program is really about providing you with the framework that works on the Web...
01:04...for you to deliver more effective applications for your GIS...
01:11...your stories that you want to tell with your maps, to become more effective.
01:16The city of Charlotte and Mecklenburg County have a long history of providing GIS data at low or no cost.
01:24We’ve always had an open data policy. The community basemap is really an evolution of that track.
01:32For the first time, we’re providing a common, consistent, standardized basemap that really provides the foundation for thematic mapping...
01:45...both internally within the city and externally.
01:49The community map program allows us to be able to give access to the vast storehouses of information that we have at the city.
01:56What we have in this program is a way of being able to deliver the services without having to make such large, initial investment.
02:05The Community Basemap program allows us to be able to move some of those assets into the cloud...
02:10...to not have to have those on our premises, yet be able to provide a level of transparency to our citizens...
02:17...to our businesses, to meet their need.
02:19So we have data from very small scales down to very large scales.
02:23Internationally, we have global coverage down to about 1 to 100,000 scale...
02:28...but we’d like to make that more detailed and more authoritative, working with local providers of information.
02:33That could be local national mapping agencies, or it could be local governments that are building datasets within their nation.
02:40This map is about you and your content...
02:43...about us being able to take the best available data sources from the professional GIS community...
02:52...an authoritative source of information, the best data...
02:57...a cloud-sourcing exercise by the professional GIS community to build a great map of the world.
03:20This is an interesting experiment. That's the way I look at it, or that's the way I looked at it a few months ago.
03:27Now there are actually hundreds and hundreds of cities that have taken this experiment, and states and countries...
03:33...and are starting to actually do it, so it's no more an experiment.
03:38The way it works is, first, there's 22 different scales of the global map, 1 to 1,000 all the way up to 1 to 1,000,000.
03:48Users are taking an online template from the resource center...
03:53...they download this template, they pour their data into the template...
03:57...and then they upload the raster tiles into the different scales.
04:02This is a collaborative effort, clearly.
04:05And it's continuous, continuous in scale so as you zoom on in, it actually gets better, like an image pyramid would do.
04:16And it's also continuous in terms of moving around.
04:21Many participants, and it's also a free, cloud-based service that you can then grab and use in your desktop.
04:29You can re-serve out on the Web in your own organization, so why should you do it? It's a lot of work.
04:37Because then you get a free basemap that's served back to you...
04:41...and it also is your map served to your colleagues in other organizations...
04:45...and it also helps us create a global map.
04:49I could talk about it for a long time and try to sell you on this idea...
04:52...but I'm finding that it doesn't take very long to understand it and do it...
04:55...and Bernie Szukalski is gonna actually just show it. Bernie, show it. That's better than me talk, right, Bernie?
05:01He always tells me that. You should shut up, let me show it.
05:06Thank you very much, Jack. The World Topographic Basemap is really a remarkable basemap.
05:13It's a multiresolution basemap that's been cartographically designed.
05:19The basemap is a true community GIS basemap, and I know many of you in this audience today have contributed to this basemap.
05:27It's received contributions from the best available sources, sources such as Natural Resources Canada...
05:35...the USGS, and the EPA, the National Park Service.
05:41Here we are in Yosemite National Park, and as I zoom in just a little bit, you'll see the detailed infrastructure...
05:48...and the trails that have been contributed by Yosemite.
05:53There've also been many contributions from state and local governments, like the state of Arkansas.
06:00Here's Denver County in Colorado. And many cities across the globe. Here we are in the city of San Francisco.
06:09I think what I find most fascinating about this contribution is the extra detail with the trees that have been added to the basemap.
06:17The city of Boston is a very new addition, so this was just added last week.
06:22So this is very much a live, dynamic basemap that's continually being updated.
06:28The city of Hong Kong is also very interesting. I find this interesting because it has labels in multiple languages.
06:36And here's another recent addition. This is from the city of Toronto.
06:41Now this has some remarkable detail as I zoom in, you'll see here, those contour lines are 1-meter contours.
06:48Now despite the fact that this content has come from a variety of different sources all across the globe at a variety of different scales...
06:56...using that template that Jack talked about, it's been brought in seamlessly into a worldwide basemap that all of us can use.
07:06Now we focused a lot on the world topographic basemap...
07:09...but there are other basemaps that are part of ArcGIS Online that also receive community contributions.
07:15Here's the world imagery basemap, which includes 15-meter or better coverage across the entire world...
07:22...and it includes more detailed information like that you see here for the Czech Republic.
07:29It also has 1-meter or better resolution for thousands of cities and towns outside of the U.S.
07:36Here we are in the Sydney area, and you might recognize the opera house there.
07:40And here we are in Brussels. This is really spectacular imagery.
07:46In the United States, it has 1-meter or better resolution, and that's been achieved by compiling data from a variety of sources...
07:54...federal, state, and local sources as well as imagery from commercial providers.
08:00This here is Petco Park just across the street from where we are. There's the Omni Hotel and there's the convention center.
08:07Now even though some of this content is from commercial providers, it's free for all of us to use.
08:15The world streets basemap is another multiresolution basemap, and it includes detailed streets for the entire globe...
08:23...and for major cities, it includes building footprints like you see here in Rome.
08:29There's also been some recent updates to this basemap. I'd like to highlight just a couple of those.
08:34Let's zoom in to Tokyo where we see the new basemap addition for that city.
08:40And here we are in Thailand and we can zoom into Bangkok and see the detailed streets that have been added there.
08:48ArcGIS Online also contains other layers that we can use to construct our own maps.
08:53For example, here's the terrain base and the world reference layer from the topographic basemap.
09:01Here I've inserted another ArcGIS Online layer.
09:04We have a series of demographic, thematic layers available.
09:08This is household income, and I've inserted it in those two other layers to create this map.
09:14And here's the geologic map of North America.
09:18We also include content from other providers.
09:22From Microsoft we include the Bing Maps roads, also the aerial and the hybrid basemaps.
09:30And we also have added OpenStreetMap.
09:35ArcGIS Online basemaps then represent an excellent way for you to start your map...
09:39...and also a great place for you to contribute some of your content.
09:44Now before I turn things back to Jack, what I would like to do is take you for a look behind the scenes...
09:50...and show you how I made this presentation.
09:52This is something new.
09:54This is ArcGIS Explorer Online, and it has a similar look and feel and some of the same capabilities...
10:01...as the downloadable desktop version that you might be familiar with.
10:05But this is a lightweight version that runs entirely in a browser, and to create the presentation you just saw...
10:11...I connected to ArcGIS Online Services, added some titles, and captured these slides that you see here.
10:19Now we’ll be coming back to this in just a few minutes. What I’d like to do now is turn the stage back to Jack.
