In arcgis I want to find from various forests fires shp files how many times parts of a particular forest were burnt during the last 70 years. Is there a way to count overlapping polygons?

  • Are you trying to find such a dataset or do you have data and you are trying to do an analysis? Your question is not clear. – Evil Genius Sep 17 '15 at 11:48
  • What do you mean by "various shp files?". Do you have data about the fires separately for every shp? What about satellite images of the area?? I don't fully understand your question. You can work with satellite images and analyze vegetation indexes as NDVI and NBR index. – geo_dd Sep 17 '15 at 11:49

Assuming you have multiple independent polygon shapefiles of fires for a specific area, you can use the following workflow:

  1. Merge your shapefiles into one
  2. Use the Count Overlapping Polygons script tool

The resulting polygon shapefile will have a count associated with the shapefile, which you can then use in your symbology.
