MapsBank project map.
This project consists in free topographical maps creating and distributing for GPS navigators Garmin.
The reason for the project creation was insufficient informativity and clearness of Garmin Topo maps, that did them of little use for travelling along the rugged terrain.
At the project creation the special attention was given to 2 points:
To make a map of the most clear and easy for perception by using simple and clear symbols and considered map specification distributing on zoom levels.
To make a map more informative by data adding, which were received with the help of satellite images decoding.First of all these data are about the vegetative cover.
Vegetation is divided into 2 types: woods (dense vegetation) and vegetation (thinned vegetation). Unfortunately, clouds, smog and some other factors complicate image decoding a lot. Therefore the boarder between woods and vegetation isn’t absolutely exact.
The USA, Canada, Australia maps creation is planned.
