Hi folks
Here's a spatial analysis I can't seem to quickly figure how to approach. I have some shapefiles
(same attributes, similar locations, but different time slices) that I need to average certain
attributes from each shapefile where they intersect spatially.
Intersecting them in ArcGIS hasn't worked since no single location has values throughout the entire
shapefile series (several thousand files).
I guess I need an alternative geoprocesing function that allows empty timeslices in my series to get
through. Or some spatial statistic function that can take many files as input and calc basic stats
from each file's attributes.
Any suggestions? Feeling like there must be some easy answer that I'm not able to find. Thanks!
Jesse
