I have a dataset that consists of animal sightings along a road and I want to calculate the density of points (sightings) along that road. My primary goal is to measure sighting hot spots, but I also want to subsequently look at the habitat characteristics associated with these hotspots. Kernel and point density do not seem appropriate b/c I only have measurements along this road (a line) I have no measurements of occurrences at locations away from this line. I'm using ArcGIS 10.3 Suggestions?

  • I don't have arcgis but I suspect you might get more help if you could share your dataset or a small portion of it for someone to analyze and reproduce to provide an answer. – kttii Nov 11 '16 at 21:05
  1. First use Generate Network Spatial Weights in ArcGIS. This tool will generate a matrix file from network that you will use it in other tools
  2. Use the matrix file in Hotspot Analysis tool . with this method you use the hotspot analysis alonge the path. You can use the Matrix file for other analysis.
