If you are just
interested in
digital maps as a cheaper way of obtaining a map which you can store on
your computer and print out what sections you want then you need to
read no further.
But with a digital map you can do much more! With decreasing prices of GPS and portable computing equipment, the way to navigate across unfamiliar terrain is changing rapidly. With a basic GPS you can load in a series of waypoints and say 'follow that route' to the GPS unit. But a handheld PDA or Smart Phone either with an integrated GPS or linked to one can display the route on a moving map as well as recording your track. Even with a basic GPS you can load a digital map into a utility and plot your route on a PC (or Mac) to send to your GPS. Maps are currently available for some or all of each of the 'warm islands' : Lanzarote, La Palma, La Gomera, Mallorca, Madeira, Menorca as well as the Sierra Aracena and Alpujarras areas of southern Spain. Also the main walking areas of Tenerife. These maps are available from Instant Books or Walkingworld. As well as the maps themselves, we make available calibration files that 'fix' the map onto its place on the earth. All the maps and calibration files use the WGS84 datum. Maps are available as 8-bit .png files. Calibration files are available (free) as .map, .jpr. cal, .gmi and .tfw files. Before you buy your first digital map, download the test pack here, unzip it and follow the instruction in the 'readme.txt' file in the package. Calibration files are currently available for all maps as MAP, JPR, CAL, GMI and TFW files. The set of calibration files is available to download here. Please note that whilst we use our best endeavours to make the maps and calibrations as accurate as we can, you download and use them on the understanding that DWG and it's associates will not be responsible for any loss or injury resulting from their use. This is our understanding of the calibration files you need to use but please check your software supplier's site :-
We are trying to make these maps as widely usable as possible but we don't know everything and can't always keep up with changing technology. So we welcome constructive feedback and will endeavour to make the site evolve to meed your needs. Please Email us with corrections or additions! |

![]() As an example, this is a fragment (actual size) of the La Palma South map. The image has been loaded into GPSU (which created the dotted grid lines from data in the calibration file) and part of a track recorded by a GPS unit overlaid in red. |
