Urban Expansion Analysis Techniques

This video tutorial on the JSN RS Solution YouTube channel guides viewers through creating gradient directions for urban expansion studies. It covers estimating land cover areas, creating buffers, and using GIS tools to create and edit gradient directions. The tutorial also discusses converting features to polygons and merging data, providing a comprehensive guide for urban mapping and analysis.
