Course Number and Title: GIS 120 Data Acquisition & Management
This course addresses the interpretation of a variety of data formats available in global information systems (GIS). It introduces the fundamental concepts of primary GIS data creation and addresses quantitative techniques for collection, classification, and management of geographical data.
- Explain the various procedures in data collection. (CCC 4, 5; PGC 1, 7, 8)
- Collect, record, and edit spatial data. (CCC 2, 4, 5, 6; PGC 1, 3, 5, 7)
- Create spatial data. (CCC 2, 3, 4, 5, 6; PGC 1, 3, 5, 7, 8)
- Produce and manage a GIS database. (CCC 1, 2, 3, 6; PGC 1, 3, 5, 7)
- Demonstrate professional and ethical conduct, as expected in industry. (CCC 1, 3, 4; PGC 1, 7, 8)
See Core Curriculum Competencies and Program Graduate Competencies at the end of the syllabus. CCPOs are linked to every competency they develop.
