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

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

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

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

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

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

15
GIS data
  • 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

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

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

18
