  1. Introduction to GIS Presented By: J. Mark Young East TN Region GIS Workshop November 15-16, 2007

  2. What is GIS? • G - Geographic • I - Information • S - Systems

  3. Why Use GIS? • Because much of our work is inherently spatial in nature • Because we deal with a wide variety of complex issues in many disciplines conducive to modeling • Because we frequently create information well-suited to storage in databases • Because we make frequent use of maps and mapping

  4. Conceptual Framework of a GIS Computer Hardware Resources Component Resources Component Database Component Personnel Mapping Software Spatial Data Data Input Presentation Database Component Storage Modeling Management & Analysis

  5. Basic Elements of a GIS • Points • Lines • Polygons

  6. Spatial Information Coordinate systems, Projections, Datums

  7. Examples of GIS Programs • ArcGIS (ESRI) • ArcView (ESRI) • IDRISI • MapInfo • Imagine (ERDAS) • ENVI (RSI) • 3-D TopoQuads (DeLorme) • X-Map (DeLorme) • MapTech

  8. Free or Low-cost GIS Programs & Utilities • fGIS (MN Dept. Nat. Res.) • DNR Garmin (MN Dept. Nat. Res.) • GIS Tools (dlg2shp, tgr2shp,sf1table, etc.) • DRG Clip • Global Mapper • Manifold GIS • USA PhotoMaps • ArcView & ArcGIS Extensions
