I am trying to draw a census tract on a Google map. It looks like Google Maps lets you draw polygons using longitude and latitude coordinates. However, the data that I have is not longitudes/latitudes.
The specific dataset I have looks like this. The "spatial reference" for this data is 3857. But after looking up this spatial reference on this page, I still am not quite sure how to go about drawing the shape to the map using longitudes/latitudes.
I assume that this sort of thing can be done with GIS software or command line tools, but I am more interested in code libraries or APIs that could make this possible. Also, if anyone knows of a better source of census tract shape data which is more compatible with Google Maps, that would be great too.
