Derived sources and methods
In this practical oriented lesson, you will
- how to digitize practically (points, lines and polygons).
- the functionality of digitizing in order to capture the data in GIS. The procedure is illustrated step by step through Animation.
- spatial data through scanned documents using onscreen digitizing, automated and semi-automated conversionmethods.
Learning Objectives
- Existing data could be commonly available as a map. Conversion of a paper map to digital features can be accomplished by the digitizing a paper map and the automated conversion of scanned map. You will learn both methods.
- The details of digitizing steps are software dependent. However, these are similar. You will learn step-by-step digitizing point, line and polygon features through the animation. It is recommended that the software manual of your digitizing software should be made available and your digitizing software installed on your system before starting reading the Map Digitizing Unit. Then relate the knowledge you gain from the Map Digitizing Unit to your digitizing software manual. As the nature of the unit is practical oriented study, you should follow digitizing tasks using your GIS software based on the knowledge gained. Otherwise, you will not learn this unit.
- You will learn automated conversion step-by-step through practical exercises. After reading the content of Map Scanning and Automated Conversion, download the PDF version of exercises and R2V software. As the nature of the unit is practical oriented study, you should follow step-by-step automated and semi automated conversion exercise using free R2V software based on the knowledge gained. Otherwise, you will not learn this unit.
