ESCI 224 - GIS: Spatial Analysis

Semester Offered: Spring
1 unit(s)

(Same as GEOG 224) Geographic information systems (GIS) are increasingly important and widespread packages for manipulating and presenting spatial data. While this course uses ArcGIS, the same software as Cartography, the primary focus here is spatial analysis (calculating patterns and relationships), rather than map design for data visualization. We explore a variety of techniques for answering questions with spatial data, including overlay, map algebra (math using multiple input layers), hydrologic modeling, surface interpolation, and site selection. Issues of data collection through remote sensing and sampling are addressed. GIS involves a more rapid introduction to the software than Cartography does; it is useful to take both Cartography and GIS (preferably in that order) to gain a more complete understanding of spatial data analysis and manipulation.
