Topographic and Cadastral Mapping Services

At AABSyS, we offer services in TopographicMapping and Cadastral Mapping. 3D Topographic Mapping is used to create comprehensive topographic maps and 3D topographic maps to the specified projection parameters, contours with ‘Z’ values, relief & plannimetric details. The Cadastral maps is a comprehensive register of the detailed real property of an area. This includes the precise location, dimensions, and other geographical classifications of properties, and individual parcels of land.

3D Topographic Maps Objective:

Preparation of the digital 3D topographic maps.

Raster to Vector conversion of topographic maps is conducted in CAD based softwares such as AutoCAD, Microstation etc. Different features of the topographic maps such as contour lines, boundary lines, water areas, vegetation, forest areas etc, are captured or digitized in different layers to generate the topographic map in vector format. 3 D topographic mapping is done by assigning the Z-values to the contours to generate the 3D terrain model of the topography.

Cadastral mapping is done from hard copies of the administrative maps, which specifies the details of each plot, roads, railway lines, water bodies, vegetation, etc. Cadastral mapping leads to effective management of public land records. The cadastral maps are linked with a backend database which has details of each plot, and their attributes.

Description:

AABSyS executed alarge-scale Topographic mapping and 3D topographic mapping project for the entire south of Belgium covering approximately 5000 square kilometers of area.

• AABSyS received about 80 hard copies of scale 1:10000 each.
• The work process involved scanning of the maps in tiff format, digitizing the topography of individual maps.
• Different features of the topography such as contour lines, boundary lines, rivers, lakes, forest areas, vegetatin areas, dwelling areas, houses, fields, roads, streets, etc, were digitized in specific layers.
• All the maps were individually digitized and georeferenced.
• Adjacent maps were then edge matched and seamlessly merged to generate a single map for the entire area.
• Z-Value was assigned to the contours to generate the 3D topographic map in vector format.

AABSyS has similarly executed several topographic mapping and 3D topographic mapping projects for its customers in Germany, Switzerland, Italy and The Netherlands.

AABSyS also undertakes large scale cadastral mapping projects which includes scanning of hard copy maps, digitisation of the maps using proper layer structure, geo-referencing the individual maps, and merging the individual cadastral maps to a single map pertaining to a specific area. Cadastral maps also show additional details, such as survey district names, unique identifying numbers for parcels, certificate of title numbers, positions of existing structures, section or lot numbers and their respective areas, adjoining and adjacent street names, selected boundary dimensions and references to prior maps.
