Hello all,
opening a raster file with values of elevation (for example DEM or DTED
files), is there a GDAL C++ API to get all the values of elevation

ogr2ogr - f SQLite Harvest.sqlite HarvestArea1.csv -dsco SPATIALITE=YES
But still no Harvest.sqlite is created.
Please tell what is the right order of the arguments. Suggest any
command combination.
