Interested in writing image processing algorithms in ArcGIS? Wondering how to write customer raster analysis functions using #python? Then check out this video from devsummit 2017 on Writing Image Processing Algorithms Using the Python Raster Function! The presenters review what the python raster function is; how it it implemented; and best practices for creating, using, and publishing python raster functions. Along the way they show compelling examples of custom python raster functions that have been written to calculate compound topographic index and site suitability. Enjoy!
