  1. Geographical Information Systems Dr Nigel Trodd

  2. Your aim is • to understand the main features of GIS You will be able to • identify technologies for handling geospatial data • recognise GIS functions • assess the relationship between GIS & other geospatial technologies

  3. What is GIS?

  4. a GIS is... a system to capture, store, check, integrate, manipulate, analyse and display data which are spatially referenced to the Earth. DoE 1987

  5. a GIS is NOT a GIS if it lacks tools to.... • capture • store • check • integrate • manipulate • analyse • display …spatially referenced data

  6. GI technologies... analogue cartography

  7. …and GIS?

  8. times are changing... ArcGIS Desktop ArcGIS Explorer ArcGIS Online ArcPad ArcGIS for: Windows Mobile Blackberry (Freeance) iOS ArcGIS Server ESRI products ESRI products 1982-2004

  9.  time

  10. …some things never change • ALL GIS store, check & integrate geospatial data • spatial referencing system • Topology • ALL GIS manipulate & analyse geospatial data • Query • spatial operations • ALL GIS display geospatial data • select layers • pan, zoom
