3. Error: “ERROR 4: Unable to open EPSG support file gcs.csv”

Solution: This error occurs when the EPSG support file is missing. To resolve this issue, you need to download the EPSG support file and set the GDAL_DATA environment variable to point to the directory where the EPSG support file is located.

4. Error: “ERROR 6: JPEG driver doesn’t support data type Int16”

Solution: This error occurs when the GDAL JPEG driver does not support the Int16 data type. To resolve this issue, you can convert the Int16 data type to a supported data type such as UInt16 before using the JPEG driver.

5. Error: “ERROR 1: PNG driver doesn’t support creation option ‘COMPRESS=LZW’”
