Orthophotomap and photogrammetry

Develop an orthophotomap begins with the planning of the flight for the area of interest. For this step we need to know the scale of the orthophotomap desired to calculate the height of flight, as well as longitudinal and lateral overlapping images. In parallel with the operation of aerial images acquisition are determined ground control points for calibrating the final image.

Using unmanned equipment (drone, UAV) the availability and flexibility of creating a project are net superior to the flight where conventional equipment are used (aircraft, helicopters). Surfaces which may be covered with such equipment are from tens of hectares to hundreds of hectares.

Aerial photography is useful both for periodic monitoring of an area of interest (landslides, lakes, ponds, etc.) and for the support of topographic and cadastral works on large areas (general cadastre, land farming, etc.).

Aerial photography application:

  • DTM’s and three-dimensional models of the terrain
  • Situation plans – contour levels
  • Data support for territorial planning
  • 3D models of urban settlements
  • Oblique aerial images and panoramas
  • Aerial images orthorectificated
  • Coastal and border mapping
  • Mapping disaster areas
  • Mapping regions with a high degree of variability
