Summarize raster layers within overlapping polygons Summarize raster layers within overlapping polygons

Python code generated for the purpose of summarizing a defined set of discrete/categorical and/or continuous raster layers within zones that may be overlapping. Many widely used GIS tools to summarize raster layers within zones are not capable of handling overlapping zones. This code also allows for the computations to be completed over a number of separate raster layers at once and...

Sediment Mercury Profile, Laguna de Pozuelos, Argentine Northwest Sediment Mercury Profile, Laguna de Pozuelos, Argentine Northwest

The data represent a shallow mercury chronology using sediment core from a playa lake system situated in a high-altitude setting in northwest Argentina. Archive samples were used from sediment core (LP07-1A) that was collected from a location (lat -22.362100, lon -66.003600) in the center of the playa-lake Laguna de Pozuelos in the dry season of 2007, when the water level was 2 to 3 cm...
