Topo Mapping – ArenaCAD

What is topography feature extraction and what is it used for?

Topography feature extraction is the process of using specialized software tools to extract specific features from point cloud data collected by laser scanners or other surveying methods.

ArenaCAD is a proud TopoDOT user, which we use to automate the extraction of features such as topography break lines, road surfaces, bare earth, buildings, bridges, and other structural 3D models. TopoDOT provides a highly productive process for managing data, assessing quality, and extracting CAD and GIS products that exceed our clients` requirements and expectations.

What are topographic plans and why are they important?

Topographic plans are drawings that represent the main physical characteristics of a terrain (buildings, fences, roads, rivers, lakes, forests, and green spaces, etc.), as well as variations in elevation between verticals or forms of relief. Topographic plans are useful for architects and civil engineers to make the best decisions regarding project design and coordination. Additionally, topo plans are documents that can establish the boundaries of a property.

In this sense, topographic feature extraction is essential for planning and making decisions regarding the development of a site, planning new buildings, repositioning existing boundaries, or designing drainage systems. Additionally, topographic plans help you save considerable time and, because they provide accurate data, reduce the risk of costly errors.

Topographic feature extraction can be used for asset management and road rehabilitation by providing accurate and detailed information about the condition of roadways and their surrounding features. This information can be used to assess the condition of the road and identify areas that require maintenance or repair. For example, topographic feature extraction can be used to identify road condition, or other defects in the road surface, as well as to measure the depth and width of these defects. This information can then be used to prioritize repairs and allocate resources more effectively. Additionally, topographic feature extraction can be used to identify and map the location of roadside assets, such as signs, signals, and barriers, making it easier to manage these assets and plan for their maintenance and replacement.
