Topography

Unmanned Aerial Vehicles (UAVs), better known as “drones”, represent a technology that allows the multispectral digital aerial photogrammetric survey in the civil field, practically a multifunction flying camera.

The flight can be remotely controlled in real-time or follow a pre-programmed flight profile, set through special software. It can have different types of sensors, including GPS receivers, accelerometers, gyroscopes, ultrasounds, various types of cameras. Their integration allows to automatically execute a flight plan prepared on a cartographic basis or, if required, to carry out manual flights for various types of use.

The positioning system and the sensors onboard allow counteracting the action of the wind, thus improving the stability of the device and consequently the quality of the surveys. Route developments of a few kilometres and heights of several hundred meters can be reached, with speeds of the order of a few meters per second.

The integration of automated systems, together with the navigation of an expert pilot, allows obtaining extremely precise flights, to guarantee the correct overlapping of the images, essential for obtaining a good photogrammetric survey and for acquiring data suitable for texturing mapping on DSM models, together with three-dimensional models of the terrain.

The data that can be acquired from the aerial platform are:

  • video footage from digital camera for inspection / reconnaissance / monitoring purposes;
  • digital images from camera calibrated for 3D survey and modelling, altimetry, renderings of artefacts and thematic cartography;
  • multispectral images (eg infrared) for precision agriculture and energy efficiency of buildings (control of thermal dispersions);
  • commercial photographs and videos, aimed at advertising events, open spaces, tourism, real estate, culture and entertainment;

Some of our works

3D survey of land of 120 hectares for the design of a golf course and various buildings.

Using aerial photogrammetry techniques and ground support, we created a 5 cm/px model with colour textures and precision altimeters, as design support for the architect manager of the project.

Mixed techniques of aerial photogrammetry from drones and high precision GPS were used.

The survey consisted in mapping the 3D models of the buildings inserted in the vineyard of S. Giuletta (Pavia). Together with the buildings, the entire terrain was reconstructed in 3D, bringing back altitudes and surfaces, to allow for a complete renovation.

The survey of the external buildings was acquired with drones and photogrammetry on the ground, then converted into 3D models together with the internal environments and the surrounding architectural details. The work was then completed with a detailed photographic survey of each room and interior detail, to allow a feasibility study of architectural redevelopment carried out later by another technical study.

The goal was to periodically scan the floor plan and the various parts of the work in progress, to verify the construction phases, which lasted 10 months.

The precision achieved, the speed of execution and the minimally invasive modality have reduced the times to a minimum and have given the customer the possibility to accurately check the current status of the work in progress, in total safety. Each survey took about 45 minutes for each session (photos and videos).

The work consisted in carrying out a complete analysis of the southwest coast of Boavista, for the realization of a tourism development project of about 200 hectares.

Scanning of various terrains was carried out, with the use of mixed techniques, for the creation of a 3D model of the territory, from which the altitudes and textured surfaces were obtained. The major intervention lasted about a week, which was then followed by the urban and architectural project of structures and buildings for residential and tourist use.

A topographical survey of an area of about 400 hectares was carried out for the construction of 3 golf courses in 2 phases (whose construction began in 2020).

The 3D reconstruction allowed the realization of an urban planning study and the insertion of the elements necessary for the construction of the first golf course in Cape Verde.

The survey of the land was carried out to create a feasibility dossier for the realization of a new hotel investment.

Scans of the territory and the coastline were carried out, as well as hundreds of aerial photographs from different heights, to identify the areas with the best sea view. The area is characterized by very high dunes, which bind the design to a careful environmental analysis. Finally, detailed cartography with altimeters and visual cones was created.
