I have an Overlay KML Polygon exported from a Shapefile, is there any way I can find weather a point is in that polygon(KML) or not? I know this is possible when we create p
You have 2 options with KML:
use a third party parser like geoxml3 or geoxml-v3 to render your KML as native Google Maps API v3 polygons, then use the way you know how. example using geoxml3
import your KML into a FusionTable, and use the ST_INTERSECTS to check for the intersection of your Polygon with a small circle around your point example using FusionTables. Note with FusionTables you can directly import shapefiles using shpescape.com
