FOURMILE CANYON FIRE A Mapping Study

Purpose A simple map of the progress of the fire by mapping of perimeter data. Map the locations of destroyed houses. Values of the destroyed homes. Theoretical response time of firefighters to the area.

Data Sources: Perimeter Data : Colorado/Fourmile%20 Canyon/ co_fourmile_canyon_ _0135_dd83.zip Roads. dl_shapefiles.htm#Roads and Highways/ Addresses of Burned Structures : follow link to FourmileFireDestroyedResidencesList_15Sept2010[1].pdf Property Values of Burned Structures : Base Map: National Map Seamless Server : DOQQ: Denver 2008, 0.6m resolution DRG: 1:24k scale; nominally the Boulder, CO quadrangle DEM: NED 1/3 arc second (10m) resolution

Further Study Mapping locations of all structures in the area along with their values. Determining actual structural value destroyed. Analysis of intact structure values.

What Did We Learn What Was Surprising. Inadequacies of the publicly available data. Better data available, but for a price. What Was Challenging. Editing the data to the point where it would be useful. An interesting exercise in how real-world data often needs to be manipulated.
