Land Cover Change Analysis with Python and GDAL - Tutorial

Satellite imagery brought us the capacity to see the land surface on recent years but we haven’t been so successful to understand land cover dynamics and the interaction with economical, sociological and political factors. Some deficiencies were found on the use of GIS commercial software, but there are other limitations in the way we apply logical and mathematical processes to a set of satellite imagery. Working with geospatial data on Python gives us the capability to filter, calculate, clip, loop, and export raster or vector datasets with an efficient use of the computational power providing a bigger scope on data analysis.

This tutorial shows the complete procedure to create a land cover change raster from a comparison of generated vegetation index (NDVI) rasters by the use of Python and the Numpy and GDAL libraries. Contours of land cover change where generated with some tools of GDAL and Osgeo and an analysis of deforestation were done based on the output data and historical images from Google Earth.

Thank you, because in internet there is not much information about GDAL, but you make useful videos
