I saw this poster created using a DEM from Lidar data. Very beautiful presentation of a river with a shallow elevation range.

EPA to Open its ArcGIS Data
Looks like the EPA will be releasing their ArcGIS data to the public using ESRI’s cloud option. Read more here.
And here is more on ESRI’s ArcGIS Open Data.
The Executive Briefing Book
Take a look at this video from the ESRI Federal GIS conference. Something new that will be released in March, The Executive Briefing Book. It is optimized for use on a tablet and organizes your content like pages in a book.
The Cahill-Keyes Map Projection
Check out this story of the man behind the Cahill-Keyes world map projection. You can buy a high resolution 61″ x 29″ wall map of it by clicking below.

ESRI’s Change to World Topographic Map sub layers
ESRI’s ArcGIS Online team made a change to the World Topographic Map on February 3, 2014. This will affect you if you reference the sub layers. Check out their blog post for more info.
If you use Geocortex Essentials, this may affect you as well. If you use the topo base map, you might see warnings from the Essentials REST manager. To fix it, do the following:
- Log into REST manager on each Essentials server
- For each site, click on the “edit” button
- You should immediately see two warnings similar to what is shown below
- Simply click “OK” to both prompts and then click “Save Site”
- Repeat for every site and you are done
Thanks goes to Doug Yates at NorthSouth GIS for the fix.
Public Radio Map
An interactive open source map showing public radio stations in the United States and Canada. Nice to know when on a long car trip. Don’t zoom out to far, I found the map slows down to a crawl and starts to trip up displaying the data. Other than that, very informative.
Super Bowl Perspectives Map
Super Bowl XLVIII will take place on Sunday, February 2, at MetLife Stadium in New Jersey. See where the game will be played and explore a series of maps that will tell you everything you need to know about the NFL’s annual championship game. Explore everything from live temperature feeds and transportation infrastructure in the New York/New Jersey region to the 10 coldest Super Bowls of all time.
Birdwatching 21st Century Style
Gotta love those robotic birds. The FAA predicted in 2012 that within 20 years time there could be as many as 30,000 drones flying over the US soil alone. Are you prepared to identify them? Get your survival guide today!
Traffic App Predicts Green Lights
A new smartphone app called EnLighten is telling drivers how long they might be waiting at traffic lights. Inventor Matt Ginsberg’s novel creation predicts when a red light will turn green.
US Census Data Two DVD Set
Demographic data down to the block level on DVD … and it’s free!
Availability: Summary File 1 is available as a two DVD set. The DVDs contain the 2010 Census Data Engine retrieval software allowing users to manipulate, display, and download data from the file.
Discs:
- U.S. Summary. DVD containing all substate data in Summary File 1. Geography: states, metropolitan statistical areas, counties, county subdivisions, places (i.e. cities and census designated places), ZIP Code Tabulation Areas, congressional districts (111th Congress), American Indian and Alaska Native Areas, Hawaiian Home Lands, census tracts, census block groups, and census blocks.
- National File. DVD containing data for larger geographic areas. Geography: United States, regions, divisions, states, counties, county subdivisions, places (i.e. cities and census designated places), metropolitan statistical areas, ZIP Code Tabulation Areas, congressional districts (111th Congress), American Indian and Alaska Native Areas, and Hawaiian Home Lands. Users needing totals for geographical areas that are in more than one state (e.g., American Indian reservations and metro areas) will find them easier to obtain from this file than from the U.S. Summary file (see above).
For more information and to order the free DVD set, visit this US Census page.
