Download data for Google Maps
If you are building an application using the Google Maps API (or other web mapping tool such as OpenLayers or Bing Maps) but you don't want to work with complex geodata formats, a simple method for extracting data is to download a CSV (comma separated value) point data set.
To download the data as CSV, add the layers you want to your map and click Download. Select the CSV option and choose the Map Projection "WSG 84 (EPSG:4326 Lat/Long)". This will transform the point coordinates into the same coordinate system used by Google Maps.
The resulting download will contain a single .CSV file per layer, with "GEOMETRY_X" and "GEOMETRY_Y" columns in the appropriate format.
