🗺️ Understanding Key Elements in our maps 🗺️
↪️Cartographic projections – maps have different projections, depending on the scale. For large scales of up to 1:250,000, this is a Mercator transverse cylindrical projection, and the system is compatible with UTM zones, except for polar areas. Medium-scale maps, i.e. in the range of 1:270,000 – 1:4 500,000, are in a Lambert true-angle projection with the north direction adjusted to the nearest meridian at an interval of 1°. Maps of continents at small scales, i.e. in the range of 1:5,000,000 – 1:120,000,000, are in the Lambert equal-area projection or Times projection. Large maps of the world are in the Times projection, and small maps, from a scale of 1:65,000,000 – in the Mollweide equal-area projection.
↪️Asymmetrical lines – these are glaciers, sea boundaries, monumental buildings, walls and fences, aqueducts, and city walls. Also, a number of point symbols are constructed with the use of asymmetrical lines, e.g. localities, power plants, solar farms, gradients, raft piers, shelters, sheds, amphitheatres, hot springs, and rapids.
↪️Special quality mode – in the special quality mode, the lines and surfaces are much more legible under overlapping names and symbols. The background under names and symbols is hold-out selectively and in 75% only, so it is possible to see the streets, roads, or railways even in locations with a high density of names and symbols. Our solution is unique on a global scale. In this mode, all overprints are preserved, not only in black, but also in other colours, necessary to make the other elements of the map easier to read.
