This workshop is about digitizing features from a georeferenced map, which is the second step in creating a GIS map file of the embedded geographic data in a paper map for the purpose of research and analysis. This tutorial follows our tutorial on georeferencing, so if you have not completed that step, check out the previous tutorial. 

As with the Georeferencing tutorial, Digitizing is a complex technical task. This tutorial will focus on the practical steps that you need to take to complete the task. Digitizing is the process of creating GIS layers of the features depicted on a paper map. Using the GIS software QGIS, we will identify features from the georeferenced map and trace them onto a new GIS layer, separating them for later analyses and visualization. 

Below, you will find a series of step by step guides to help you learn this process. When you have completed this tutorial, you will be more familiar with the tasks of Digitizing features on a georeferenced map which will be ready for display.

This workshop is about Georeferencing, which is the first step in our Introduction to GIS series. GIS means “Geographic Information System.” Georeferencing is a very technical activity but we are going to focus on the practical elements that will allow you complete the georeferencing task on a scanned image of a map. 

Georeferencing, in the most simplistic terms, is layering a scanned map (likely a print map that has been scanned and saved as an image file or a pdf file) on top of a satellite map and locating reference points (known as “Ground Control Points”) on both maps in order to align the scanned map accurately with the satellite map. By using as little as three of these Ground Control Points, you can begin to locate the scanned map on the satellite map, which is the first step to creating and embedding geographic data to that map for comparison and analysis.
