OpenStreetMap (abbreviated OSM) is a free, open map database updated and maintained by a community of volunteers via open collaboration. [4] Contributors collect data from surveys, trace from aerial photo imagery or satellite imagery, and import from other freely licensed geodata sources.
Inset maps are smaller maps that are included on the same page as the main map. They can show additional information related to the main map. Four types of inset maps are common: [6] A Locator map is of a significantly smaller scale than the main map, and is used to show the location of the main map within a larger context. They are especially ...
This page provide conventions to produce topographic maps. Topographic maps, displaying an area's relief, de facto explain many other things such as human occupation, cultivated areas, kingdoms borders, exchanges ways, etc. If you create a topographic map, note that these colorimetric values are indicatives.
In most European countries, the largest scale topographic map series is a 1:25.000 scale series. Notable exceptions are Austria (1:50,000) and Finland (1:20,000). Many non-European states limit the largest scale of their map series, usually to 1:50,000 scale, frequently due to the large size of the country covered (and hence for financial reasons).
A graphical or bar scale. A map would also usually give its scale numerically ("1:50,000", for instance, means that one cm on the map represents 50,000cm of real space, which is 500 meters) A bar scale with the nominal scale expressed as "1:600 000", meaning 1 cm on the map corresponds to 600,000 cm=6 km on the ground.
Polaris Intelligence consists of multiple modules including mapping (thematic maps, heat maps, POI maps, trade area maps), customer profiling, gravity models, customer allocation models, feature selection, data mining, and targeting. A key strength is the vast quantities of consumer geo-demographic and behaviour data native to the platform ...

These 1:25,000 scale maps were produced from the 1960s to about 1975, then abandoned, and liquidated in the 1980s (along with the scattered coverage of the 1:500,000 and 1:125,000 scale). Most were quadrangles of 7.5' by 7.5', but two unusually-shaped coverages were provided to cover Whitehorse, one being primarily 105 D/11 h but with portions ...
