Land-marks (Surveying marks) |
The land-mark is the point object of a map typologically corresponding to a rotary point of borders of a plot. Attributes of a land-mark necessarily should contain semantics NAME. Land-marks can be placed both on external, and on internal contours of a plot. Drawing of land-marks can be executed by several methods: - to put land-marks (rotary points), points from a text file in XYHN format, where N - a name (number, the name) a mark; - to give semantics NAME for point objects, plotted earlier; - to put land-marks from dialogues tasks of a direct and return task by means of the given system. At drawing land-marks from dialogues of a direct and return task of the geodetic block, it is necessary to enter in dialogues the values in columns a name of a point or a name of a surveying mark. The data specified in this position will be automatically brought into value of semantics NAME.
