GIS for Educators - Topic 9: Vector Spatial Analysis (Buffers)

Abstract

Understand the use of buffering in vector spatial analysis. Spatial analysis uses spatial information to extract new and additional meaning. Usually spatial analysis is carried out using a GIS Application. A GIS provides normally has spatial analysis tools for feature statistics (e.g. how many vertices make up this polyline?) or geoprocessing such as feature buffering (e.g. which area falls within a certain distance of this feature?). In this worksheet we look more closely at vector analysis, using buffering as an example.
