    4. 4. What is a GIS?  GIS is an abbreviation for geographic information system, which is  computer software that maps and analyzes geographic data  A GIS links location (spatial or maps) and database (tabular) information and enables a person to visualize patterns, relationships and trends.
    5. 5. What is a GIS? (Continue) Spatial or Map (Raster or Vector) This is a vector map… Database (Tabular) Polygons i.e. Properties Points i.e.Trees Lines i.e. water pipelines
    6. 6. Still Defining GIS  What do you need to use GIS? A full GIS, or geographic information SYSTEM, requires:  Hardware  Software  Data  People System  Training  Processes
    7. 7. GIS Components Hardware Computers, Networks, PEOPLE Printers, Plotters, Administrators, Digitizers Managers, Technicians, Software End users, Consumers GIS software, Database G software, OS software, Network software I S Methods or processes Guidelines, Data Specifications, Vector, Raster, Images, Standards, Attribute Procedures

    16. 16. The power of a GIS: Find all the market centres in Kenya that are within a 10km distance from major roads. Problem:  Kenya has more than 1600 towns.  Which ones of them are market centres?  How do I define a major road?  I cannot go and measure, by vehicle or foot, the distance each town is from the major road – IT WILL TAKE ME AGES!! WITH A GIS IT CAN TAKE ME 5 minutes!
