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: l structuring l formatting l conversion l modeling §GIS: transforms data with a spatial component
12
Geographic Data §spatial data §referenced to “geographic space” l coordinate system grid other l projection l 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 §1960’s & 1970’s - mainframe computers §1980’s to mid 1990’s - mainframe & minicomputers §mid 1990’s to present - PCs & workstations
15
GIS data §types l geodetic control network: surface location l topographic base: point elevation l graphical overlays: thematic data §representation l vector: point, lines, polygons l raster: grid cells l surface §metadata l information about the data l key when sharing data
16
GIS technology §hardware l organization intranet: servers & client computer stations PCs internet l considerations processing power file size (very large) data access
17
GIS technology §software l proprietary l open standard §companies l ESRI ArcInfo & ArcView ArcGIS l Intergraph l MapInfo
18
Application of GIS §table - p 12 §academic §business §government §industry §military
19
Users of GIS §Specialist: includes programmers, designers, developers §General Users: planners, scientists, administrators (us) §Viewers: everyone (our “clients”)
