  • 1 What is GIS

  • Why difference GIS from other types of information ?

    Because it always refers to certain locaties on the earth's surface.
  • why is geographical information or information about location important?

    reasons are:
    * curiosity
    * the need to survive
    * the need to sloven problems in which location or information about location plays a role
  • location is apparently so important that society has to solve many problems in which location is a crucial issue. Where can you think off ?

    *questions on environment
    *water management
    *regional economisch
  • knowing what is where, or what happens where and when, is not only a matter of curiosity, but can also be of critical importance to survive. give an example

    -seasonal high water levels in rivers
    -earthquake risk areas
    -or crop damage by extreme drought
  • give an example of a location where the activity is happening ?

    think of a highway needs a lot of space for itself, but it also has a huge influence on the location of industrial areas, housing sites and on the environment
  • Why is GIS not just a sophisticated software package?

    GIS is not only software, but it also involves specific hardware (computer, digitizing table, plotters, etc.) and procedures (techniques and orders for task implementation). According to some people (e.g. Burrough) it also includes the organisational context in which a GIS project is being performed.
  • What are the strong points of GIS

    Providing a framework for the efficient collection, storage, analysis and presentation of spatial data
    It can be used to analyse and solve all kinds of societal problems that have a spatial dimension.
  • 1.1 Knowing GIS (SS)

  • the definitions of GIS cover three main components, which one

    1. they reveal that GiS is a computer system which includes, hardware, software and appropriate procedures (task implementation)
  • what should a well-designed GIS be able to provide ?

    1.quick and easy access to large volumes of data
    2.the ability to:
    select detail by area or theme
    link or merge one data set with another
    analyse spatial characteristics of data
    search for particular characteristics or features in an area
    update data quickly and cheaply and 
    model data and assess alternatieven
    3.output capabilities (maps, graphs, address list and summary statistics
  • GIS draws on concepts and ideas from many different disciplines, give some examples.

    science draws on disciplines as diverse as cartography, cognitive science, computer science, engineering, environmental sciences, geodesy and so on.
