Returns the raster and raster band objects. Opens the raster band number stated in the optional band_number keyword argument with raster_band = raster.GetRasterBand(band_number) (the default value is 1).

Opens the provided raster file_name embraced by try - except statements to inform if and why a potential error occurred while opening the raster. To access the raster band, the below-shown open_raster function:Įnables error and warning feedback with gdal.UseExceptions() (this step is vital when using gdal). One of the most important elements when dealing with raster data is the raster band, which takes on a similar data carrier role as GetLayer in shapefile handling.

The following code block provides a function to open any raster specified with the file_name input argument. Raster data can be opened in Python code as an instance of gdal.Open('FILENAME').
