more fiddling with Blender and GIS

[Stephen Guerin]

We're preparing for a project that will be an agent-based model of wildfire
evacuation planning in Santa Fe -- Primarily a wildfire model coupled to a
traffic model with agents embedded in a social network deciding whether they
should stay in their houses or evacuate.

I'm putting Blender (http://www.blender3d.org) through its paces to see if we
can use it for the visualization (and possibly portions of the agent and/or fire
modeling).

Tonight, I tried importing Digital Elevation Models (DEM) for Los Alamos and
Santa Fe directly into Blender. Below is a Quicktime that displays 2 square
degrees between latitude 35-36N and longitude 105-107W. The movie starts in the
southwest corner (35N107W) and moves up to the northwest over the Valle Caldera
near LANL (35.5N106.5W) and then over to Santa Fe. It ends roughly just north of
Santa Fe Ski Basins looking down toward Albuquerque.
http://www.redfish.com/projects/SFWildfire/SantaFe_DEM_SRTM.mov

I used DEM files of type SRTM (Shuttle Radar Topography Mission) from an FTP
directory at NASA (ftp://e0srp01u.ecs.nasa.gov/srtm/)

I found a SRTM conversion script on the Blender Elysiun forum. The script is
very nicely packaged with a site, *great* documentation and a GUI in Blender.
The site is here:
http://uaraus.altervista.org/index.php?filename=en/content/categories/Blender/DE
M_importer.html. There's other scripts available to deal with other formats.

The documentation below is worth reading for more detail and it graphically
explains the data format of the SRTM file:

A couple of thoughts on the subject.  Traffic movement is obviously cyclical
but these cycles are also tied to various demographic and sociological
characteristics. Different groups of people travel the roads at different
times presenting different evacuations issues. Early morning commuters vs.
school buses, vs. people going out to party are examples.  So whose already
out there vs. whose home and what will it take for them to get mobile?
Witness the same issues in New Orleans which now appear to have been tied to
age, nursing home, hospital, and poverty status. It could also be
interesting to look at the dispersion of these populations or more exactly,
relative concentrations compared to fire path projections and escape routes.
Information management could be very important too relative to telling
people when to move and where to go.  Again, the social characteristics of
the crowd might be interesting.  All of this suggests a kind of fire
diffusion modeling over demographic geographically delimited time flows.

You might find the UC Santa Barbara Center for Spatially Integrated Social
Sciences interesting at: http://www.csiss.org/

Here is a text that you might find interesting summarizing some aspects of
the approach suggested in my earlier post.

Did you need both N35W106.hgt.zip and N35W107.hgt.zip or just one of  
them?

Thought I'd use them with LandSerf to see how well it works.

Hey Steve, I know it's been a good long time since you posted this,
but did you end up using Python for the agent simulation stuff as
well, or just to drive Blender's topography stuff?

Microsimulation: cars driving on the road as homeowners evacuate; as
compared to the CA wildfire component of the simulation.
