Map Demo with OpenLayers

This map uses OpenLayers to display a base layer from NASA JPL, two overlays from the USGS using ESRI map data, and pop-up markers from a tab-delimited file exported from the Drupal/CiviCRM database.

Please note that the base layer from NASA does not always load, depending on how access to their server is. The other layers are less data intensive, and should load just fine.

Click the "Show Map" button to display the map. Click the right-hand plus sign that appears on the map to show the layer options. If you turn on the "Our data" layer, you can click on the resultant markers to show popups with city and zip code.
