Hi,
I made GMT respect as far as possible the AREA_OR_POINT GeoTiff key
for read/write, but ...
The following was silently ignored (GMT uses the MEM driver)
GDALSetMetadataItem(hDstDS, "AREA_OR_POINT", "Point", NULL);
so digging here and there I found about GDALMD_AREA_OR_POINT, and in
fact this one is now taken into consideration
GDALSetMetadataItem(hDstDS, "GDALMD_AREA_OR_POINT", "Point", NULL);
However, this implies that on reading I have now to test for both
GDALGetMetadataItem(hDataset, "AREA_OR_POINT", NULL)
---- AND ----
GDALGetMetadataItem(hDataset, "GDALMD_AREA_OR_POINT", NULL)
This means that other codes that pay attention to the AREA vs POINT
thing will have to do both tests as well and if they do only the first
one, GeoTiffs created by GDAL will have the problem ignored, and quite
likely an error in coordinates will follow.
So the question is, why this name duplication (AREA_OR_POINT vs
GDALMD_AREA_OR_POINT) and why GDALSetMetadataItem() ignores the
AREA_OR_POINT key?
Thanks
Joaquim
