How accurate are the GPS files?
Some websites offer thousands of GPS files, also known as GPS track consolidators. Often, the GPS files have not been reviewed, appear to be inaccurate or are just drawn on a map.
We have spent considerable time recording and editing the over 140 GPS files in our collection.
We have recorded the trails several times to improve the accuracy of the data using a GPS device (the Garmin GPSMAP 60Cx) with a 12 channel SiRFstar III™ high-sensitivity GPS receiver that continuously tracks and uses up to 12 satellites to compute and update the position in the field.
Especially in extremely narrow canyons (kloofs), GPS readings can be limited. In rare situations when the SiRFstar III™ could not pick up the satellite signal, we have corrected the data manually.
When you download our GPS files, you are guaranteed to have high quality and accurate GPS files you can rely on in the field. As owner of the guidebook, you have free access to the GPS files. To ensure others do not mess with our GPS files, we really ask you not to post these on the Internet as we can no longer control the quality of the files. Safety is our priority.
