planimetriemeting

Planimetrie meting, also written as planimetric measurement, refers to the measurement of planimetric features on a two‑dimensional plane. It focuses on the horizontal positions of objects or boundaries (the x and y coordinates) on maps or plan views, while elevations or z-coordinates are not included. Planimetric data are essential for creating accurate representations of land parcels, roads, buildings, and other features on a map.

The primary purpose of planimetric meting is to determine distances, directions, and areas within a plane. It is widely used in surveying, cartography, and geographic information systems (GIS) to produce planimetric maps and to populate map layers with precise geometric information. Planimetric measurements are often a foundation for cadastral surveys, urban planning, and land-use documentation, where the exact planar shape and size of features matter.

Methods for planimetric meting vary from traditional to modern. Field methods include using measuring tapes, electronic distance measurement (EDM) devices, total stations, and GNSS/GPS systems operated in a projected coordinate system to obtain horizontal positions. In digital workflows, planimetric data can be generated by digitizing boundaries from maps or aerial imagery and by applying planimetric calculations to derive lengths and areas. Planimetric metering can also be performed with planimeters or digital algorithms that trace a boundary to compute the enclosed area.

Outputs of planimetric meting are planar coordinates, lengths, and areas often stored in GIS formats or CAD drawings in a specified projection. While planimetric data omit elevation, they are frequently combined with altimetric data in 3D analyses when needed.
