How to Compare DSMs in Python: Analyze Surface Elevation Changes and Generate Heat Maps

Leave a Comment / GIS, Python, QGIS, Raster /

Introduction Digital Surface Models (DSMs) represent the Earth’s surface, including all features such as buildings, trees, and other objects above the ground. They are widely used in geospatial analysis for applications like urban planning, flood modeling, and vegetation monitoring. By comparing two DSMs from different time periods, we can detect changes in surface elevation caused […]

In this tutorial, we’ll walk through how to process and save raster chunks in parallel using Xarray and Dask. This technique is particularly useful when working with large raster datasets where chunking and parallel processing can significantly improve efficiency. Prerequisites Before we begin, ensure you have the following Python libraries installed: You can install them
