Figure 3From: Evaluating local vegetation cover as a risk factor for malaria transmission: a new analytical approach using ImageJHomestead buffers for vector dispersal. DigitalEarth’s QuickBird image from June 2007, 2.4 m/pixel. Buffers were created at 50, 100, and 500 m to simulate vector dispersal using ArcGIS 9.3. This image is representative of those used in the analysis from Google Earth.Back to article page
