The data corresponds to ECA zones (Emission Control Area) around he United States. The point (lat=25.9556,lon-78.1239) should be outside the polygon, but it is detected inside. The point (lat=25.95,lon-78.1239) is correctly detected outside the polygon so I suspect I ran into some kind of singularity or something... Any help would be greatly appreciated!"
