GIS Concepts

Pre-processing- Some gps data from the survey stations had to be fact checked. Also notes on survey effort were used to determine which transects were actually carried out during 2008.

Buffer- Buffer operations were used to provide a measure of cover by observers during their surveys. I could also have used buffer as a tool to eliminate areas of high traffic from potential future survey design.

Dissolve- The Dissolve function was used to create a single polygon from the several unconnected segments at the western end of the plateau.

Spatial Analyst

Raster Calculator- Was used to create a re-classified the National Elevation Dataset DEM to illustrate the lack of safe bird habitat free of the transmission of avian disease.

Feature to Raster- Was used to create the final raster to contain malaria risk data for the survey area.

Clip- Was used to combine the data from the malaria risk rast to the survey area for 2008.
