GPS to GIS:Top 10 GPS for GIS Skills ANDREW CAREY ELI CRAWLEY
Objectives • Check List for Project Planning • GPS for the Office • GIS for the Field Food for Thought Real Examples
THE WHAT – GIS ? A Geographic Information System or GIS is a computer system that allows you to map, model, query, and analyze large quantities of data within a single database according to their location. • Create maps • Integrate information • Visualize scenarios • Present powerful ideas, and • Develop effective solutions!!! http://www.epa.gov/reg3esd1/data/gis.htm
THE WHAT - GPS? GPS – Global Positioning System (US Dept of Defence) GNSS – Global Navigation Satellite System – generic term for all satellite navigation systems GLONASS – GLObalNAvigationSatellite System (Russian System)
THE WHY COMMUNICATION ! Field - Office Personnel
TOP TEN GIS GPS
2. Projections • Datum • Map Projection • World File
