Converting vectors to rasters
Occasionally, you want to convert vectors to rasters to facilitate using raster analysis tools such as the raster calculator.
Getting ready
You'll need a vector layer; this can be a point, line or polygon layer. The best results generally come from polygon layers. We will use geology_wake2000reclass.shp. This file is the result of the earlier clipping vectors recipe with a new column added that codes the geology types as integers. For reference, you'll also use elev_wake_500m.tif as a matching raster for the area of interest.
How to do it…
In order to be useful in analysis, here's a checklist:
- Is the vector data in the same projection as the rest of the raster analysis data? If not, reproject it first. Check the following ...
