Parameters of local coordinate system

Previous Top Next

Dialog "Parameters of local coordinate system" allows to change metadata of source map with the purpose of its display and the editing by using the specified values.

Parameters of local coordinate system influence only the display of coordinates and are considered at editing a map. But the map will be stored in a standard coordinate system, defined at its creation.

Parameters of local system of coordinates can be set in two ways - concerning some existing system (as a rule, offset relative to CS-63 for preset area and number of a zone), or having entered completely parameters as at creation of a map of type "Topographical local".

If change of metadata of source map is carried out by installation of offset concerning the chosen reference system it is required to choose, first of all, one of the suggested list of the reference system and then to enter all necessary changes.

If change of metadata of source map is carried out by installation of all parameters of reference system it is necessary to enter completely parameters as at creation of a map of type Topographical local.

For it you need to specify an axis meridian, number of a zone, offset by X and Y.

Additionally it is possible to set latitude of the main point, scale on an axial meridian, a turn angle of axes, parameters of an arbitrary spheroid and datum.
