I have the following (attachment):
- 2D latitude file (240x446)
- 2D longitude file (240x446)
- 2D surface elevation change data (240x446)
How can I write these into a 2D grid geotiff file? I tried the following, but it only works for lat, lon arrays (1x240 and 1x446)...
R = maprasterref( ...
'RasterSize', size(Z_2017_2018), ...
'XWorldLimits', [double(min(y(:))) double(max(y(:)))], ...
'YWorldLimits', [double(min(x(:))) double(max(x(:)))], ...
'ColumnsStartFrom', 'north', ...
'RowsStartFrom', 'west', ...
'RasterInterpretation', 'postings');
key = struct( ...
'GTModelTypeGeoKey',[], ...
'GTRasterTypeGeoKey',[], ...
key.GTModelTypeGeoKey = 1;
key.GTRasterTypeGeoKey = 2;
key.ProjectedCSTypeGeoKey = 3413; % Greenland Polar Stereographic

You can refer to a similar question answered here. The provided solution makes use of georasterref and geotiffwrite function to write the lattitude and longitude data to the GeoTiff file.

For those searching for the same question: I wasn't able to write the file into a GEOTIFF in Matlab. I resolved the problem this way:
In that case, I have a XYZ file that I could import in GIS software. There, I converted it into a GEOTIFF file.
