I am trying to extract soil data from https://soilgrids.org/ using their very new Soilgrids REST API. They have a special website (http://rest.isric.org/soilgrids/v2.0/docs) where I am able to enter the coordinates and get the soil data that I require.
But for some reason, I am not able to get data for many coordinates that I tried. For example, I can get data for (lat=39.1813855,lon=-77.1827295) but not for (lat=39.1825835,lon=-77.1828465).
Why can't I get data for the last point (lat=39.1825835,lon=-77.1828465)??
