Hypothetical plume data as ASCII text in AtlasGIS ".bna" format generated with this python script, which clearly could be improved to produce more realistic output.
Two more made-up space time data sets to mess with Tracking Analyst. Here are 24 hours (one hour steps) of a plume a plume expanding in kml format , in Arc's old "generate" format (with an associated text file to hook times to plume polygons here), and in the old AtlasGIS ".bna" format, and the same 24 hours of ten critters running around randomly at different rates, near the plume, recorded at one minute resolution. (Does the difference in time resolution cause trouble?)
BTW, Here is a python script to generate kml polygon data like that: plumekml.py . It seems that kml is the new gen-file.
As requested in class,
here is that outfile.kml that had the
