Planimetric 3D feature extraction is important for land administration and management. Planimetric maps provide better insights as to where certain features are located on land. These details enable land administrators to take better decisions. Planimetric mapping is also indispensable for carrying out change detection in order to understand how the built environment has changed over time, update existing maps and monitor economic growth. Magnasoft has a rich experience in providing planimetric mapping for counties, municipalities, real estate, forestry, transportation and hydrography.
A planimetric map consists of manmade and natural features represented as lines, closed polygons and points using aerial and satellite images. Planimetric mapping involves the extraction of earth’s features such as roads, building footprints, river outlines and closed water bodies.
The methods used to obtain the information depicted on a planimetric map can be collected from orthorectified aerial digital photography that has been orthorectified, or using data captured through aerial lidar mapping and conventional land surveying techniques. Planimetric mapping follows image processing workflows after aerial imagery has been triangulated and orthorectified, providing vector basemaps to be used for topography mapping and geospatial analysis workflows.
Magnasoft offers both 2D and 3D digital planimetric mapping services. We have a consistent track record of providing the most accurate planimetric information with a precision of 10 cm for aerial and 50 cm for satellite imagery. We not only deliver traditional classification services but also provide value-added products such as surface models, contour models, raster models etc.

Digital Planimetric mapping involves the extraction of the earth’s features such as roads, building footprints, river outlines and closed water bodies. These features are provided as vector basemaps for further use in GIS and topographic mapping workflows, as well as specific applications including urban mapping. Planimetric data enables governments and businesses to take better decisions and provide better insights as to where certain features are located on earth.
Planimetric mapping is used for land administration and management, as it allows for change detection, updating existing topographical maps, improving spatial planning decisions and control for illegal settlements. Planimetric mapping is also used for urban mapping, providing the basis for 3D city models. Such models are a prerequisite for digital twins, which are virtual replicas of cities that are used by city governments to plan, test and monitor their physical, economic and community structures.
Magnasoft has a rich experience in providing planimetric mapping for counties, municipalities, real estate, forestry, transportation and hydrology. We offer both 2D and 3D planimetric mapping services, where 2D planimetric mapping is independent of elevation and captures feature outlines in a two-dimensional format using orthorectified aerial images, whereas 3D planimetric mapping involves the identification and extraction of horizontal and relief features in a 3D format.
