GEOTRILHO - cartography & photogrammetry

Cartography consists of the set of studies, scientific and technical operations involved in mapping from the results of direct observations or documentation study, as well as of its use. The production of cartography comprises the most varied purposes, such as: Engineering Projects, Architecture Projects, Environmental Studies, data for GIS production, Land Use and Planning, etc.
We put make available to our customers the Digital photogrammetry, using the UAV technology (English acronym for Unmanned Aerial Vehicle). We are thus qualified to perform fully automated flights for acquisition of aerial photography, which once processed, allow us to produce 5 cm spatial resolution orthoimages. It is also possible to extract the shape, dimensions and position of objects present in the photographed scenario . We have therefore gathered the metric and semantic information that allows us to produce, among others, the following products:
- Photogrammetric points
- Fieldwork
- Vectorization
- Cartographic production
- DEM - Digital and Elevation Models
- DSM - Digital Surface Models
- DTM - Digital Terrain Models
- High Resolution orthophotomaps and orthoimages
- Visual Inspection support documentation
