• What does “100% GPS surveyed” mean?

It means that we personally went in the field to collect our data. We have walked, biked or drove through all the trails, dirty and paved roads with GPS devices in order to collect field data (as well as Points of Interest and many more features) and all what is needed to precisely represent the territory.

    • How often are 4LAND maps updated?

The 4LAND maps are updated continuously. Unlike other maps on the market which are updated only after many years, we, at 4LAND, are committed to work every day on the data of our maps, working in close collaboration with the Alpine Rescue and some local mountain guides to provide annually updated maps.

    • Is the app Avenza Maps free?

Yes. However, there is a paid version for professionals. For more information visit: https://www.avenzamaps.com/maps/version-comparison.html

    • Do you need a data connection to use the maps on the phone?

No. Only to download the map in the phone you must be connected to the internet; after that, the map is saved into the device and can be used offline.

    • How do I download the latest version of a map in Avenza Maps?

Before purchasing a map in the app store Avenza Maps it is necessary to create an account Avenza. Periodically, we update our maps in the store; hence, simply log into your personal account and check by yourself the date of your download of the map and compare it with the upload of the map in the store. If the upload date is most recent than your download date, then there is an updates. Click here for detailed instructions.

    • Can I view maps on my desktop or laptop computer?

Regrettably, no. At this time, downloaded maps are only available through the app on your device and cannot be transferred to your desktop or laptop computer. Contact us directly if you want to acquire any maps for use on a desktop or laptop.

    • Is there a digital version of each printed map?

Yes. There is always correspondence between printed maps and digital maps. The difference is that while the map is printed double-sided, the corresponding digital version the two sides are sold individually. However, there are some digital maps that do not have the correspondent printed version.

    • What is Polyart?

The Polyart is a type of synthetic paper made for commercial printing which provides a high quality as well as good durability. Polyart is a film of high density polyethylene to which a real coating is applied. The Polyart synthetic paper can be used in the most arduous conditions. It is tear-proof, waterproof, resistant to continuous manipulation, oil and many chemicals.

    • What is LiDAR?

The LiDAR is an airborne remote sensing technique that is used to obtain an extremely precise three-dimensional model of the terrain based on the altitude and of X and Y coordinates detected for each square meter of surface. For our maps we employ this type of terrain representation after running numerous process, often with enhancements done manually, to render the morphology and altitude in mountainous areas as accurate as possible. This is why our maps appear almost in relief!

    • Why the heights on 4LAND maps are far more accurate than in other maps?

It would not make much sense to spend a lot of time to collect GPS data (trails and P.O.I.) with an accuracy of 1-2 meters if then we were to use for our maps the heights taken from old technical maps. We recalculate all the heights from LiDAR data with an accuracy of about a meter. Furthermore, we select strategically the spots where calculate the heights such as crossroads, near point of interests, etc. It is an extremely innovative method in cartography, and there are in fact the paradoxical consequences from the comparison with the other maps. One example is Cima Brenta (3151 m s.l.m.) in the eponymous group, that taken from LiDAR data reveals be higher than Cima Tosa (3136 m s.l.m.) for years mistakenly referred to as the highest peak of the Brenta Dolomites!

    • How are represented the Mountain Bike paths in 4LAND maps?

After consulting with many bicycle fans and local mountain bike guides we have created an innovative way to represent the traits available for MTB. Each road or path segment available for MTB is marked with a color that specifies the difficulty, so as to create a network from which the rider can build up the preferred route.
