Introductory GIS courses build an understanding of how GIS describes real world features within an information system. This course builds on that knowledge to introduce methods for spatial analysis. Analysis always involves inputs, methods, and outputs. The inputs are the spatial layers and tables; methods are functions, proceedures or algorithms; and outputs are new or derived spatial layers, tables and reports. In the lab, we will focus on carefully considering inputs and methods so we can better evaluate outputs. We will consider geoprocessing both vector and raster data and automating functions using ArcToolbox, ModelBuilder, and Python scripts.
