What is a GIS?  G:Geographic  I:Information  S:Systems Czech Technical University in Prague - Faculty of Transportation Sciences Department of Transport Telematics

What is a GIS?  G: Geographic  spatial data  geo- referenced  S: Systems  users  hardware  software  I: Information  databases  representations  Czech Technical University in Prague - Faculty of Transportation Sciences Department of Transport Telematics

Data vs. Information vs. Knowledge  Data is a collection of attributes about the entities/objects/elements in the space and time.  Information is the organization of data such that it is valuable for analysis, evaluation and decision making.  Knowledge is the awareness and understanding of facts, truths or information gained in the form of experience or learning. Czech Technical University in Prague - Faculty of Transportation Sciences Department of Transport Telematics

Where did GIS come from?  GIS is built upon knowledge from geography, cartography, computer science, information systems, and mathematics  Geographic Information Science is a new interdisciplinary field built out of the use and theory of GIS Czech Technical University in Prague - Faculty of Transportation Sciences Department of Transport Telematics

Knowledge Base for GIS  Computer Science/IS  graphics  visualization  database  system administration  security  Geography and related  cartography  geodesy  photogrammetry  landforms  spatial statistics  Application Area  public admin.  planning  geology  mineral exploration  forestry  site selection  marketing  civil engineering  criminal justice  surveying Czech Technical University in Prague - Faculty of Transportation Sciences Department of Transport Telematics

GIS Definition  “A geographic information system is a computer-based information system that enables capture, modeling, storage, retrieval, sharing, manipulation, analysis, and presentation of geographically referenced data”  (Worboys and Duckham, 2004, p.2). Czech Technical University in Prague - Faculty of Transportation Sciences Department of Transport Telematics

Generalization And Models GIS main functions  Spatial Data Management  Capturing  Data Update  Data model  Conversion functions  Printing  Spatial Analyzes  Map and Result display Czech Technical University in Prague - Faculty of Transportation Sciences Department of Transport Telematics

Why does GIS Matter?  Almost everything happens somewhere  Knowing where some things happen is critically important  Position of country boundaries  Location of hospitals  Routing delivery vehicles  Management of forest stands  Allocation of funds for sea defenses  GIS is a special class of information systems that keeps track not only of events, activities, and things, but also of where these events, activities, and things happen or exist Czech Technical University in Prague - Faculty of Transportation Sciences Department of Transport Telematics

Why Study GIS?  80% of local government activities estimated to be geographically based  plats, zoning, public works (streets, water supply, sewers), garbage collection, land ownerrshiip and valuation  a significant portion of state government has a geographical component  natural resource management  highways and transportation  businesses use GIS for a very wide array of applications  retail site selection & customer analysis  logistics: vehicle tracking & routing  natural resource exploration (petroleum, etc.)  precision agriculture  civil engineering and construction  scientific research employs GIS  geography, geology, botany  anthropology, sociology, economics, political science  Epidemiology, criminology Czech Technical University in Prague - Faculty of Transportation Sciences Department of Transport Telematics

Brief History of GIS?  1960 – 70s Innovation  First GIS – Canada Land Inventory  DIME US Bureau of Census  Harvard Laboratory for Computer Graphics  Major vendors started (e.g. ESRI, Intergraph)  Landsat satellite launched  Key academic conferences (e.g. AutoCarto)  1980s Commercialization  Commercial GIS software (e.g. ArcInfo)  First GIS textbooks  First global data sets  Clinton Executive Order  2000s Exploitation  Internet becomes major deliver vehicle  More than millions of active users Czech Technical University in Prague - Faculty of Transportation Sciences Department of Transport Telematics
