Python: Working with Raster Data

The integration of map algebra with Python opens a new dimension for raster analysis and the automation of geoprocessing workflows. Using a real world example, this session will include an introduction to the Spatial Analyst ArcPy module, best practices for using the raster object and classes to expand your modeling capability, using raster functions to optimize performance, and using NumPy arrays to extend your analysis.

Presented by Elizabeth Graham and Nawajish Noman

where can i implement it if i want to ? is there a repo for code and gdb files used?

Nice video! Where would you set your extent if you're using, for example, a for loop to loop through a list of rasters and in each iteration of the loop you perform multiple spatial analytical functions on the raster using other data (both vector/raster) with different extents? I'm guessing arcpy.env.extent preserves the extent (even if analysis is performed on the data) until that statement is met again in the code??
