I am new to Drupal and I wanted to display KML polygon overlay on maps. The KML's polygon overlay should be editable and the updates should be maintained. I could achieve the same using OpenLayer's native fields which gives me Polygon something like this:
POLYGON ((73.388681037812 19.112484040461, 73.608407600313 17.107729704053, 74.619149787812 14.060401771206, 75.498056037818 12.263265526929, 76.508798225317 9.9347768243063, 77.080087287813 9.6316334577929, 73.388681037812 19.112484040461))
I instead wanted to go with KML file. So I tried out OpenLayers KML Layer. I tried a lot but I could not configure it properly so that my site could read the KML file and display its contents on the map. There is no definitive guide on how exactly to integrate it into the website.
Basically am not able to perform the 2nd step mentioned in configuration:
"Visit /admin/build/openlayers/layers/openlayers_kml_layer and select which filefields in each content type are KML files."
I also tried Geofile which also promises of showing the KML overlay on map, but unfortunately could not get it to work either.
I need help here guys, about how to add OpenLayers KML layer into project, and whether my requirements would be served with the module I am trying to integrate?
Also, is it possible that registered user would be modifying KML file using OpenLayer and the same is revision controlled too?
Thanks for any suggestions and pointers.
