Digital Maps
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. The combination of digital map and calibration files allows these maps to be loaded into any of the software listed below except those shown as 'import not supported'. 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, MCD 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 :-
| GPS Software | GPS units supported | Software for own hand-held device | Calibration file format |
| Memory-map | Most | Pocket-PC and Smart phone | JPR |
| GPSU | Nearly all | no | JPR or TFW(1) |
| Ozi-Explorer | Most | Pocket-PC with Windows Mobile/CE | MAP |
| MacGPSPro | Most | no | MAP or JPR |
| TrekBuddy | no | Symbian, Palm, Blackberry, Windows Mobile with JAVA |
MAP |
| Fugawi | Most | Widows Mobile and Palm(4) | JPR(2) |
| Anquet | Most | Pocket-PC and Windows Mobile | Import not supported |
| Mapyx/Quo | Most | Pocket-PC | TFW |
| Pathaway | Most | Windows Mobile and Palm(3) | JPR,MAP,TFW or CAL |
| TouratechQV | Most | interface to Pathaway | CAL |
| Cartopro | Most | no | MAP, CAL or TFW |
| GPSTuner | no | PocketPC | GMI(5) |
| Garmin | Garmin | Garmin's own | KMZ(6) |
| Satmap | Satmap | Satmap's own | Import not supported |
| Tracklogs | Some Garmin & Magellan | no | Import not supported |
| GPSGO | no | Windows Mobile | MCD |
| Viewranger | no | Symbian 60 Smartphones | Import not supported |
| Mobile Atlas |
no |
Many Phones and PDAs
including Palm, iPhone and Android |
Mobile atlas tiles(7) |
| (1) TFW files
supported in GPSU version 4.93 and later (2) New JPR files created 23May2008 to resolve an incompatibility with Fugawi (3) Pathaway can be 'fed' from Touratech, Fugawi and Softmap PC software (4) Fugawi are withdrawing their own handheld software in favour of Pathaway (5) GPSTuner only accepts JPG images. Download the PNG and use the MapCalibrator downloadable from their website to convert from PNG to JPG (6) From November 2009 Garmin have a 'Custom Map' facility on Oregon, Colorado and Dakota devices. To use these maps on these devices, instead of the standard maps and calibrations, you must download the KMZ files which contain both the maps and the calibration for Garmin in one file. To save space on the Garmin devices, the individual walks are in separate files. There is a sample to test here. These KMZ files can also be viewed in Google Earth.. There are more details of the maps available here. (7) See here for a description of Mobile Atlas tiles. |

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.

If you have reached this page searching for map calibrations then this link may be of interest.
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.
