The following list is not exhaustive: GPS – to get locations using longitude, latitude and altitude measurements
GIS – for creating a spatial database and mapping. Mapping software is optional. Could use regular database or even paper files to store data.
Internet – for staging maps on the Internet.
NB: For an introduction to longitude/latitude visit http://www-istp.gsfc.nasa.gov/stargaze/Slatlong.htm For detailed educational and technical information on GPS/GIS use any Internet search engine combining the words Geographical Positioning Systems or visit www.trimble.com/gps/index.shtml.To illustrate, here is a GPS reading example: "N 07 01 44.0; E 038 80 16.1; 1,720 m".The numbers refer to:(1) the latitude North of Equator. 07 are degrees (from 0 to 90), 01 refers to minutes (from 0 to 59) and 44.0 are seconds (from 0 to 59),(2) the longitude East of the Greenwich line (which goes North-South through Greenwich in London, United Kingdom), also in degrees (from 0 to 180), minutes and seconds, and(3) the altitude above sea level.The coordinates shown here as an example are from a coffee growing area in the Southern part of Ethiopia.
