You have very large LIDAR surveys, topographic or bathymetric vector data, or meshing data: by integrating all these disparate data sources into projected or geographic coordinates, you want to build a unique and scalable digital meshin model that you can manage – correct, complete, update – and that you can use by delimiting a study area.
TeraSurf accepts many data formats (vector, raster, meshing data) as input and output, and thus increases the potential of your GIS.
Why choose TeraSurf
From the simplest to the most complex
If your input data is from various sources and precisions, TeraSurf allows you to build and manage a digital meshing model for each data source, each range of scale for example, with a resolution adapted to the accuracy and density of the data.
Thus, the set of models can be used as if it were a single numerical model: in the study area, TeraSurf rebuilds on the fly a model at the wanted resolution by drawing in the different selected models according to the priority assigned to each of them.
TeraSurf is an autonomous, generic and complete tool for the management and exploitation of your digital models.
- Modeling from point, line and polygon geometries or meshing data.
- Combination of models using arithmetic and boolean operators.
- Exploitation of the models: contours, break lines, characteristic lines (peaks, thalwegs), draping of vector data, path of drop of water, calculation of volumes, etc.
Features that make it an indispensable tool
TeraSurf has been designed to best meet your needs. Among all its features, it stands out in particular by:
- Unlimited volume of input data.
- A spatial coverage of complex and discontinuous form: watercourse, reach, coastal strip, archipelago.
- Management / scalability: local modifications, updates, extensions or completions.
- The interpolation of slopes when creating a model from isobaths or contour lines.
- The creation of models of water bodies in plane intersections from dimensions measured on water scales or simulated.
- The exploitation of models possibly reduced to a study area (rectangle, polygon, multi-polygon).
- Geographic coordinates: analysis algorithms applied to the sphere to avoid any distortion.
Application fields
Designed to integrate unlimited data volumes, to manage digital models of complex spatial coverage, TeraSurf is particularly suitable for projects such as:
- Exploitation of LIDAR surveys in urban or rural areas.
- Coastal management: continuous land/sea modeling by integrating bathymetry, topography, lidar surveys, etc.
- River studies: modeling of the minor bed/litter, calculation of flood fields.
- Marine or fluvial bathymetry: anchorage charts, maintenance of the navigation channel.
