Unit 3: Raster Analysis

Hopefully you've found some comfort with finding and manipulating geographic data.  Now it is time to put some of that technical confidence to use.  How might we use multiple criteria to assess the landscape?


Workshop C: Finding Yellow Birch

In this lab we'll explore how to manipulate boolean rasters to perform basic overlay operations, as well as explore terrain mapping.  After we get comfortable with digital elevation models (DEMs) and boolean rasters, we'll create "ordinal" rasters that score the landscape for how likely it is suitable habitat for yellow birch.

Workshop D: Delineating Groundfish Zones

In this lab we'll extend our practice with raster analysis.  After we get comfortable with the bathymetric and vessel traffic data, we'll create "categorical" rasters that describe a myriad of conditions that might help us locate groundfish habitat.
