Digital Cadastral DataBase (DCDB) is a computerised map or 'spatial' location showing property boundaries normally in relation to adjoining and other close properties or parcels of land. Commonly used as a basic layer of data used in map based computer programs that gives an outline of the legal boundaries of a property.
The boundaries of the latitude bands are parallel circles (dashed black lines in figure 1), which do not coincide with the boundaries of the 100,000-meter squares (blue lines in figure 1). For example, at the boundary between grid zones 1P and 1Q, we find a 100,000-meter square BT, of which about two thirds is south of latitude 16° and ...
Allows 'OSM ExternalData elements' to be added to the map. This can be an administrative boundary, highway or other linear map element that has been assigned a wikidata Q value. (e.g.: map-data=Q83065 will add the city boundary of Leicester.) The map item needs to be on the same place as the map itself.
However, it differs from global latitude/longitude in that it divides earth into 60 zones and projects each to the plane as a basis for its coordinates. Specifying a location means specifying the zone and the x, y coordinate in that plane. The projection from spheroid to a UTM zone is some parameterization of the transverse Mercator projection ...
The default map image, without "Image:" or "File:" image1 = USA Tennessee relief location map.svg An alternative map image, usually a relief map, which can be displayed via the relief or AlternativeMap parameters; top = 38.1 Latitude at top edge of map, in decimal degrees; bottom = 33.6 Latitude at bottom edge of map, in decimal degrees; left ...
The default map image, without "Image:" or "File:" image1 = USA Wyoming relief location map.svg An alternative map image, usually a relief map, which can be displayed via the relief or AlternativeMap parameters; top = 45.2 Latitude at top edge of map, in decimal degrees; bottom = 40.8 Latitude at bottom edge of map, in decimal degrees; left ...
The Mercator projection in normal aspect maps trajectories of constant bearing (called rhumb lines or loxodromes) on a sphere to straight lines on the map, and is thus uniquely suited to marine navigation: courses and bearings are measured using a compass rose or protractor, and the corresponding directions are easily transferred from point to ...
So, the most general case is a table of standard names and the corresponding standard codes (and its official geometries). Germany (DE) with each first-level administrative subdivision labelled with the second part of its ISO 3166-2 code. The 21 top-level 2-digit "region" of hydrologic unit boundaries, using the HUC geocode conventions.
