  6. Chapter 1 Introduction to Geographic Information Systems

  7. Definitions • “…a system of hardware, software, and procedures designed to support the capture, management, manipulation, analysis, modeling, and display of spatially referenced data for solving complex planning & management problems” (Rhind, 1989)

  8. Definitions • “…a computer system capable of assembling, storing, amnipulating, and displaying geographically referenced information…” (USGS, 1997) • “…a set of computer-based systems for managing geographic data and using those data to solve spatial problems” (Lo & Yeung, 2002)

  9. a computer system that allows the analysis and display of data with a spatial component (Phillips, 2002) Definitions

  10. data: collection of facts/figures information: data in useful form knowledge: what you have intelligence: what you use Definitions

  11. allows the transformation of data into information via: structuring formatting conversion modeling GIS: transforms data with a spatial component Information System

  12. spatial data referenced to “geographic space” coordinate system grid other projection source land survey GPS aerial imagery represented at a “geographic scale” Geographic Data

  13. approach to using GISystems what to do & how to do it Geographic Information Science

  14. Table, page 6 1960’s & 1970’s - mainframe computers 1980’s to mid 1990’s - mainframe & minicomputers mid 1990’s to present - PCs & workstations GIS History

  15. types geodetic control network: surface location topographic base: point elevation graphical overlays: thematic data representation vector: point, lines, polygons raster: grid cells surface metadata information about the data key when sharing data GIS data

  16. hardware organization intranet: servers & client computer stations PCs internet considerations processing power file size (very large) data access GIS technology

  17. software proprietary open standard companies ESRI ArcInfo & ArcView ArcGIS Intergraph MapInfo GIS technology
