This question already has an answer here:

I have a shapefile whose Coordinate Reference System's NAD_1983_CORS96_StatePlane_ Florida_East_FIPS_0901_Ft_US/ESRI:103257.

How do I convert this shapefile into a .geojson file that can be read onto a Google Maps object when working with Google Maps API?
