In this class, students learn how to create land-cover maps from satellite imagery. Raw satellite images are imported into computer software programs, preprocessed for radiometric and geometric corrections, enhanced for better interpretation, and finally classified into land cover maps using various techniques. These land cover maps are then assessed for accuracy through field ground truthing using geographic positioning systems. The class incorporates hands on computer labs, field trips, and an independent project. Topics include selection of map projections, use of scales, generalization, data input and processing, color, visualization of spatial data, and map production.
Emphasis is placed on effective communication through graphic design.
Exercises guide students through increasingly complex methods of data collection and cartographic construction. Topics include data structures, conversion of data to GIS formats, spatial analysis such as overlay and buffering, use of relational databases, customizing the GIS interface, and management of GIS projects. Laboratory exercises demonstrate the principles with GIS software packages. This course examines both the singular physical and human aspects of the State, from its unusual geologic history, climate, and vegetation, through its earliest inhabitants, to its present day diverse population and trend-setting economic, political, and cultural atmosphere. Issues discussed include changing populations and regional differences, evolving urban areas, water resources, agriculture, and forestry.
