[netCDFJava #LEC-363579]: Get data through lat lon coordinates

Greetings!

I think I was able to find the file you are using:

https://e4ftl01.cr.usgs.gov/MOLT/MOD16A2.006/2001.01.01/MOD16A2.A2001001.h18v05.006.2017068142633.hdf

and here is the code I have to read in the grid:

---

import java.io.IOException;

import ucar.nc2.dt.GridDatatype;
import ucar.nc2.dt.grid.GridDataset;

public class modis {

    public static void main(String[] args) {
        String location = 
"C:/Users/lesserwhirls/Desktop/modis/MOD16A2.A2001001.h18v05.006.2017068142633.hdf";
        try (GridDataset gds = GridDataset.open(location)) {
            GridDatatype grid = 
gds.findGridDatatype("MOD_Grid_MOD16A2/Data_Fields/LE_500m");
            System.out.println(grid.getUnitsString());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

---

What version of netCDF-Java are you using?

Cheers,

Sean
