Configuring the base map in the reference map

Last modified: Wed, 03/15/2017 - 23:09

There is a small reference map in the upper left of the LAS user interface. This map requests tiles from a WMS server which are used as the base map. The location of the WMS server used for the base map is now configurable.

Configuring the "mini-map"

You can now configure the WMS server URL and the layer name into the HTML document that hosts the user interface. In the LAS distribution directory, the file you need to edit is WebContent/UI.vm. In the file will find 4 servers listed in the comments at the top of the file. To use one of these servers, edit the meta links below the comment and replace the content values with the URL and layer name you want to use. As far as I know these are all servers which will accept public connections from any web site, but if you have your own WMS server and base layer data set, you can use that as well. The WMS server needs to be able to return PNG images projected on the EPSG:4326 to work with LAS.

After you make the change in your LAS distribution you will have to redeploy the application to your Tomcat server (use the command "ant deploy"). If you just want to make the change temporarily directly in the deployed server you can edit the webapps/las/UI.vm file directly in the deployed directory and the new map will be used the next time the page is loaded. That change will get wiped out if you redeploy your LAS.
