PHOTOGRAMMETRY SERVICES

HIGH-RESOLUTION MAPPING FROM GEOREFERENCED IMAGES

Photogrammetry is a mapping method that involves reconstructing the shape, dimensions, and position of land or structures from aerial photographs. Using professional drones, Altivis provides high-precision topographic data, orthophotos, 3D models, and detailed surveys.

WHAT WE OFFER

• Acquisition of georeferenced imagery using drones equipped with high-resolution sensors

• Generation of 3D point clouds and Digital Terrain Models (DTMs)

• Creation of high-resolution orthophotos (2 to 5 cm/pixel)

• Production of textured 3D models and mesh reconstructions

• Extraction of contour lines, profiles, and volume measurements

• Delivery in GIS and CAD-compatible formats: GeoTIFF, OBJ, DXF, LAS, and more

APPLICATION AREAS

• Large-scale topographic mapping

• Construction site monitoring and progress tracking

• Urban, land, and cadastral studies

• Infrastructure projects, roadworks, and earthmoving

• 3D modeling of buildings, heritage sites, or industrial facilities

• Surface and volume calculations (quarries, landfills, stockpiles)

OUR METHODOLOGY

• Precise Flight Planning with GCP (Ground Control Points)
  Accurate flight planning using ground control points to ensure high-precision results.

• Capture of Nadir and Oblique Images for Enhanced Detail
  A combination of nadir (vertical) and oblique imagery for more detailed data collection.

• Photogrammetric Processing with Professional Software
  Processing of imagery using advanced software such as Pix4D, Agisoft Metashape, ContextCapture, and more.

• Quality Control, Field Verification, and Georeferenced Data Export
  Ensuring data accuracy through field verification and the export of georeferenced data in various formats.
