They are even making maps during the football game!!!We are here at the MapSAR Training at New Mexico State University, Las Cruces. The class had about 20-25 participants total and we kicked it off with a public colloquium on Friday night. Then on Saturday we walked through MapSAR tutorials using a missing person search scenario in Yosemite National Park. On Sunday we finished up the lessons and repeated them using local New Mexico data to reinforce the elements learned in the tutorial. The class had a great mix of SAR volunteers, GIS students, and some people who have done both SAR & GIS.
So, because it went so well, I thought I would take a moment to document some resources for the students and those who could not make it today.
Base Data
http://rgis.unm.edu/browsedataThe best resource for data specific to New Mexico is RGIS, the New Mexico Geographic Information System Program, where you can browse and search for a diversity of datasets, as indicated in the figure on the right. All data offered through RGIS are FREE.The Boundaries folder for instance has Wilderness Boundary layers available for download. The Transportation folder contains datasets like the Continental Divide Trail. Vector datasets like these should be downloaded as shapefiles and added to ArcMap.
Aerial imagery is available in the Digital Orthophotography folder and elevation data (Digital Elevation Models) in the Elevation folder. For instance, here is a statewide 60m DEM. There are also 7.5' USGS Topographic maps available in the Topographic folder. Raster datasets like these come in a variety of data formats including .tif, .sid, etc. Read up on adding raster data to a map.
Just in case you need a refresher on vector vs raster....
Vector Data
Raster Data
A spatial data model that defines space as an array of equally sized cells arranged in rows and columns, and composed of single or multiple bands. Each cell contains an attribute value and location coordinates. Unlike a vector structure, which stores coordinates explicitly, raster coordinates are contained in the ordering of the matrix. Groups of cells that share the same value represent the same type of geographic feature. Definitions from the GIS Dictionary

- Beyond MapSAR (Analysis tools using DEM such as slope, viewshed, elevation profile, etc)
- Dr. Michaela Buenemann & New Mexico State University Geography Department and New Mexico SAR Council for hosting this event
- Jon Pedder and the Sierra Madre SAR Team for developing MapSAR
- NAPSG Foundation for sponsoring the event
- Lorri Peltz-Lewis and the GISCorps for their continued support
Stay tuned...
- The training materials will be posted as soon as we have incorporated feedback
- We will use this as a template to help other instructors teach this in their own community
- Teaming up with a local University has proven to be a great way to introduce GIS experts and SAR Teams!
