Map Tile Information

The tiles created by the AWMC are graciously hosted on Mapbox servers, courtesy of ISAW, and are created by Ryan Horne from AWMC data produced by Richard TalbertJeffrey BeckerRyan HorneRoss Twele, Audrey JoRay Belanger, Steve Burges, Luke Hagemann, Ashley Lee, and others.

 
Presented below is  a list of our offerings along with a short description and some associated meta-data, followed by a brief code introduction. As usual, please contact us if you have any questions or suggestions (or if you have space to mirror the tiles!). All of our map tiles are released under CC BY-NC 3.0 and are completely free for any academic, personal, or non-commercial use.

Code:

See here for code examples to use the tiles in an application.

 

Raw Data:

The raw data behind the tiles (shapefiles, rasters, etc) can be found here: http://awmc.unc.edu/awmc/map_data/

 

 A quick warning for users of OpenLayers:

Since OpenLayers brings in Mapbox tiles in the xyz format, you will see many 404 requests by default. One way to avoid displaying these is by adding this .css to your application:

.olImageLoadError { 
 /* when OL encounters a 404, don't display the pink image */
 display: none !important;
}

We have not yet figured out a way to avoid requesting these ties entirely, but when we do we will post it here.

Please see the individual listings below for data citations. It is suitable for most applications when left on its own, or  in combination with water polygons for a particular time period (archaic, Roman, etc).
