Hello, folks, I tried to build a Raster Attribute Table (denoted as RAT below) for a GeoTiff raster file(attached as “test.tif”) in C within Visual Studio 2008. This C file was compiled through and there was no errors reported.
I used GDALSetDefaultRAT function, it was successful. But when I used GDALRATCreateColumn function to create RAT fields, it was always report errors. I tested how well the c++ file “rfc40_tests_hfa.cpp” works(Downloaded from the GDAL forum). I found this code only works on HFA driver, i.e., .img grid file, not .tif grid because the same errors occur when I changed the driver from “HFA” to “GTiff”, I downloaded and used gdal-110-1500-core.msi, which is gdal 1.10 version API library for Windows. I worked with C++ under Visual Studio 2008 professional. I have attached the GeoTiff file as "test.tif" and my C source code file "gtiff_rat.c". I also attached the c++ file “rfc40_tests_hfa.cpp”. My question: Is GDAL API able to be used to build a Raster Attribute Table for GeoTiff raster? Any help will be appriciated. Regards, Sam
