GIS Tutorials

( … into the woods … )


Unit 1: Introduction to Geographic Information

Learning GIS and cartography is fun and rewarding, all it requires is a little time and effort.  This first unit is designed to lead you toward making your first map, assuming you've had little to no experience with GIS and design programs.  

Workshop A: Symbolizing Data

In this workshop we'll learn how to download, import, and symbolize geographic information for the state of Maine.

Unit 2: Introduction to Thematic Cartography

Much of the fun of modern cartography is in mapping thematic information  -  that is, data that do not directly relate to the physical landscape or navigation.  These themes could be anything:  population dynamics, weather phenomena, traffic patterns, etc.

Workshop B: Make a Choropleth Map

In this workshop we'll learn how to manage vector polygon data and symbolize it properly when displaying quantities.

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.
