Services and Applications
Digital Elevation Model
The digital elevation model allows the extraction of data concerning terrain heights and various analyzes in CAD or GIS software.
Land Use Map
For a detailed analysis of the terrain surface, divisions of areas and resources being used.
Required for environmental and geological studies. Can be provided in Degrees and Percentages.
Online and interactive resource where flood quotas can be easily viewed and manipulated derived from the digital elevation model.
We use post-processed Geodetic GPS to provide the highest accuracy in topographic surveys.
The point cloud is the basis of photogrammetry. After processing can easily extract three-dimensional coordinates and generate various files for analysis and ground measurements. The following image is from a topographic survey at Pedra do Bico do Papagaio in Itajaí – SC – Brazil
Millions of Points
It is an image that was orthorectified or whether it has been geometrically corrected to eliminate distortions and coincide with a parallel projection plane, thus allowing use in bidimencionais measurements in various CAD and GIS software.
The advantage of including a geo-referenced orthophotograph in a project is the richness of detail that can be obtained in addition to the normal topographic survey.

For Google Earth
The orthophoto can be exported to the KMZ format. Used with google earth mainly for quick queries to clients. The images are a comparative between the original Google earth image and the orthophoto image.
Digital Elevation Model (DEM)
Through a DEM file it is possible to work with elevations for contours generation, slope map, volume and surface calculation.
The image below represents the contours generation extracted from a DEM (grayscale image).
