Spatial Analysis of Accessibility of Wells using Map Algebra
Completion requirements
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).

7.1. Convert Raster Cells to Point Vectors
To present the end result we can style the accessiblewells
layer. However, it is nicer to present the wells as point features on
the map. Therefore we need to convert the well pixels to point vectors.
1. In the Processing Toolbox go to Vector creation | Raster pixels to points.
2. In the dialogue choose the accessiblewells layer as the input Raster layer. For Field name, enter Accessibility. The raster values will be saved under this field in the attribute table.
Choose wells.shp as the output Vector points layer.
3. Click Run, then Close when the conversion is finished.
