  GPS Information for EWP Maps.

Maps - Home

Our maps vary in their usefulness for GPS users. We provide a 0-5 numerical system to give an indication of the GPS friendliness of the map.
GPS=5 indicates a map that can easily be used with a GPS.
Such a map would have lines of latitude and longitude marked at frequent intervals or have an internationally recognised grid system.
The poorest rating is GPS=0. On such a map it would be impossible to locate yourself from a GPS reading and you would have to build a latitude / longitude or other grid for yourself.

KIKilimanjaro3Lat Long 10' intervals
MKMount Kenya4Lat 2' Long 5' intervals
RURwenzori2Non-standard 1x1km grid.
Conversion to UTM/UPS hence lat. long. possible by formula: to Easting in metres (ie 10 fig. Grid Reference) add 807500 to gain UTM/UPS reference; from Northings subtract 31200.
E.g. 8 fig. Grid Ref of Margherita on EWP map is 12257418. This becomes 12250+807500 and 74180-31200 and hence a 12 fig. UTM/UPS reference of: 819750 042980
