Introduction to geographic information systems and the Nile Goblet tool

  1. 1. Catherine Pfeifer ILRI/IWMI and Yenenesh Abebe IWMILearning Event on ‘A Decision Support Tool for Mapping Suitability of REM-Strategies in the Nile Basin’ Addis Ababa, Ethiopia, 6-7 December 2012
  2. 2. Plan Crash introduction into what is GIS Importance of GIS in agriculture The concept of suitability The Nile-Goblet open source tool Test yourself the Nile Goblet tool
  3. 3. What is GIS Geographic, so we know that GIS has something to do with geography. Information, so we know that GIS has something to do with information, namely geographic information. System, so we know that GIS is an integrated system of geography and information tied together.
  4. 4. What is GIS? Computer system  Hardware  Computer, plotter, printer, digitizer• Software and appropriate procedures Spatially referenced or geographic data People to carry out various management and analysis tasks
  5. 5. What is GIS ? Geographic layer = geographic data  Vector data  Point  Lines  polygons  Raster data  grid
  6. 6. GIS for agriculture Technology/practices/crops depend on the bio physical environment Best practices are location specific GIS can inform what works where  Suitability analysis
  7. 7. Suitability analysisSelect a location where given conditions for a best practice are metExample : terraces Slope : 12-50% Rainfall 800-2000 mm annual rainfall Not on vertisol
  8. 8. Nile Goblet tool Open source GIS software for suitability analysis No need for prior GIS knowledge Dataset has been prepared for RMS in the Ethiopian Blue Nile Flexible tool, can be adjusted for different location and different practices technologies. http://nilebdc.wikispaces.com/Nile+Goblet+tool+and +training
