comment Given a Lat and Lon, identify if the point is over land or ocean?
Thanks! That is much easier than the wormhole I got into trying to mask netCDF files directly using nco although nco makes it look easy, it is difficult to understand.

perhaps I was confusing the issue by linking to the other page. I want to convert the raster points to polygon squares, 1 square per point.

I actually want to make little polygon squares that go to the midpoints, so that I can click them and get tooltips.

comment What is the best free web GIS browser?
do any of these support generating a heatmap from a grid - not of the density of points density but from a grid of values (like this question)?
