I work in a library providing geospatial services and I have a patron with about 60 surveys with perceived accent regions in Mexico. Individuals drew on maps where they think people speak with different accents in Mexico. The end goal here is to have a map that combines the results of these surveys into one map.
Here is what one of the surveys looks like-
He's got them georeferenced and then digitized to individual feature classes in a geodatabase. Now we've got polygons overlapping one another in different layers like so (I'm only showing 2 for simplicity). Each polygon in the layer represents a different accent region
First feature class-
Second feature class-
Both classes layered on top of one another
How can I combine these 60 feature classes to make a map showing these perceived regions? The end result as something like a heat map would be perfect. Would that work very well with nominal data? I've poked around online and haven't found much help. I'm just struggling getting my head around visualizing the combination of all those layers.
I'm using ArcGIS 10.1 Build 3035.
