Contour lines

Terra Excess can generate contour lines from topographic survey data in a very simple way. All you need to do is select the points  with elevation values and create a “Main surface". Once done, you should choose the interval and draw the contours. Contour lines in Terra Excess can also be labeled. Generated contours can be used as a base map for designing and implementing various construction projects or creating topographic plans and maps. (video)


By using volumetric survey data (sets of points with elevation data), Terra Excess can accurately calculate stockpile volumes, extraction quantities as well as volumes of earthworks, quarries and more. The software creates a triangulated irregular network (TIN) for the representation of the surfaces and computes the volumes between them by using prism volume calculations. This is the most accurate method for estimating volumes, whose accuracy depends only on the quality of the data entered. (video)


Survey points entered in Terra Excess can be clearly visualized and edited. They can be scaled in size and some of their properties can be hidden – for instance Number, Elevation or Description. (video)


The possibility to export points and contour lines generated in Terra Excess in the DXF file format allows users to transfer the data between various CAD software products. (video)
