APRS (Automatic Packet Reporting System) is a well used system among the amateur radio community. In two words, the idea is to connect a GPS to a radio transmitter, and send the actual position over the air. A very appreciated programm to run this service is UI-View. To display the position of the radio stations on a map, UI-View requires a graphic file containing the map, as well as a calibration file describing the reference coordinates of the map. TAHO.EXE (since version 2.07) is able to generate both files out of OSM datas.

  13. Set the calibration file tickboxes to UI-View only (XI)
  14. Click "make maps" (XII)
  15. The map file (*.png) and associated calibration file (*.inf) have been generated in a subfolder of taho: ..\Mapnik\map. Copy or move them to your UI-VIEW map folder. (Typically C:\Program Files\UI-View32\MAPS by default)
  16. Start UI-View, or restart it if it was already running
  17. You can load the new map in UI-View by pressing "F2", or via the MAP / Load a Map menu
