Geographic Information System (GIS)

A Geographic Information System (GIS) enables the retrieval of data in space, allowing for its synthesis, which is useful for informed decision-making. This is done using vector data (points, lines, polygons) or Raster Data (images: TIF, JPG, PNG, …). It makes it possible to represent, analyze, collect, process, model, store data and create new databases for the production of new maps.

3D Imaging and Scanning

The result of a 3D laser scanner scan is a set of millions of 3D points (XYZ) representing the surface of the object being surveyed: “Point Cloud”. From this, we proceed to the 3D reconstruction of the object in a very precise way with a real or colored texture. An important decision-making tool, its speed and accuracy are well established. Equipped with an innovative and high-performance hardware package, our services in this field are as follows:  Precise surveys of assets, buildings, villas, cranes, etc.

BIM

We use an intelligent 3D digital model for a construction project. This is supported by using tools like the CHCNAV RS10 Handheld SLAM 3D Laser Scanner with GNSS RTK to capture precise 3D data of existing infrastructures or environments. This data is then imported into a modeling environment to generate highly accurate, reality-based 3D models. The RS10 is widely applied in surveying, construction, BIM, industrial inspection, and other fields requiring accurate 3D spatial data.
