Photogram-metry, which means “metric representation using light”.
Photogrammetry is a tecnique that can automatically generate spatial and descriptive information using multisensorial systems.
Our instruments are: RGB cameras, thermal cameras, multispectral cameras and LiDAR
What do we get are high-resolution orthorectified aerial images, 3D models (made using structure for motion), digital terrain models (DTM), vigour maps and vegetation indices.
Why should you integrate drone-captured photogrammetry in your projects?
- It allows you to determinate objects and their characteristics without physical contact;
- it’s a simultaneous survey of many points, resulting in a great quantity of information;
- measures are made off-line (in retrospect, after the survey) and they can be repeated, changed or controlled; surveys and post-elaboration are quick and fast;
- it is a cost-effectiveness operation: lower unitary cost of a map produced with the photogrammetric method compared to those made from topographical surveys;
- accuracy uniformity.
The fields of application are:
- Topographical surveys: making or updating topographical, thematic or numeric (GIS) maps;
- Territory monitoring: making of large scale maps for urban and territorial planning or for engineering works;
- Agricultural or forestry census;
- Archaeological surveys of cultural heritage;
Cadastral and environmental surveys;
- Infrastractutral control;
- DTM and orthophotos.
