Himanshu Arora, I haven't done much with it lately, but this might be of help to you. Basically, starting from a list of coordinates (which will be interpreted as vertices of a well-formed polygon - no error checking yet), you can output a list of plus codes that correspond to the polygon's area, in any precision you like:
https://github.com/bocops/open-geotiling/blob/tile-area/java/org/bocops/opengeotiling/TileAreaPolygonalBuilder.java This is currently just available in a branch because I haven't found time to test for all sorts of bugs. It should be mostly OK, though. On Friday, January 18, 2019 at 5:15:21 PM UTC+1, Himanshu Arora wrote: > > Thanks a lot Barry! > > Apologies, I did not clarify too well initially.
