Course Outline
This is a five hour online course that discusses the basic data used in GS and its considerations of implementing a GIS application. Topics of the course are: data acquisition and input; georeference; accuracy; use; sharing; data types; components of a GIS; sources of error in a GIS; data in LIS; scale; types of projections; data distortions; coordinate systems; Data formats; and Examples of data formats.
This course includes
a multiple choice quiz at the end, which is designed to enhance the understanding
of the course materials.
