GDAL (Geospatial Data Abstraction Library) is a popular open-source library for reading and writing geospatial data formats. It provides a Python API for developers to access its functionality. To use GDAL in Python, you first need to install the GDAL library and its Python bindings. You can install it using pip by running the following command: ``` pip install gdal ``` Once installed, you can import the `gdal` module in your Python code and use its functions to read and write geospatial data files. Here's an example of how to open a raster file using GDAL in Python: ```python from osgeo import gdal # Open the raster file raster = gdal.Open('path/to/raster.tif') # Get the number of bands num_bands = raster.RasterCount # Get the raster size width = raster.RasterXSize height = raster.RasterYSize # Get the projection and geotransform projection = raster.GetProjection() geotransform = raster.GetGeoTransform() # Read the first band as a numpy array band = raster.GetRasterBand(1) data = band.ReadAsArray() ``` This is just a simple example, but GDAL provides many more functions for working with geospatial data in Python.
