Spatial Analysis of Accessibility of Wells using Map Algebra
完成条件
In this tutorial we'll apply map algebra to determine the accessibilty of wells. This tutorial was developed together with Kurt Menke (Bird's Eye View GIS).
6. Combine the Three Conditions
After calculating the Boolean maps for the three conditions we need to combine them to come to the final result.
1. Use the Raster Calculator to combine the three conditions. Because all Boolean results for the conditions need to be true we have to use the AND operator. Call the output layer accessiblewells.tif.
2. Check the resulting raster layer and style the layer.
