Aerial Photogrammetry and LiDAR Survey with Drone
With Geomap, you can acquire high-resolution geospatial data from drones and transform it into reliable digital models. Ideal for urban, industrial, infrastructural, environmental, or agricultural surveys.
For over 25 years, we have supported .
From flight planning to digital model in 3 clear steps
Planning and surveying with drone
Each project begins with technical flight planning, tailored to the area, morphology, and objectives of the survey.
We define the sensor type (photogrammetric or LiDAR), the operating altitude, and the overlap between images or laser beams to achieve maximum accuracy.
The survey is performed by certified operators, using professional drones equipped with high-precision GNSS with RTK correction, even in areas inaccessible from the ground.
We thus acquire georeferenced images or LiDAR data ready for processing, in full compliance with regulations.
Photogrammetric processing and LiDAR data
The acquired data is processed with professional software to generate high-precision geospatial products.
From photogrammetric images, we obtain orthophotos, DSMs (digital surface models), and DTMs (terrain models); from LiDAR data, we obtain extremely high-density point clouds.
Each output is optimized to ensure:
Metric accuracy, even over large or complex areas
Terrain readability even under trees (thanks to LiDAR)
Compatibility with GIS, BIM, or CAD systems
The result is a solid technical foundation for reliable 3D analysis, design, and modeling.

Model production and delivery
Starting from the processed data, we produce the final digital models: high-resolution orthophotos, point clouds, DTM/DSM, contour lines, meshes, and 3D surfaces.
The files are provided in the most popular industry formats (GeoTIFF, GeoJPEG, SHP, LAS, E57, XYZ, LAY, etc.), ready for integration into your work environments.
Upon request, the models can be uploaded directly into Geomap software, for easier use for facility, asset, or city management purposes.
Each delivery is accompanied by technical reports, metadata, and dedicated support for data use.
Geomap is certified according to the UNI EN ISO 9001:2015 standard for the provision of:

Frequently Asked Questions about the Aerial Photogrammetry and LiDAR Survey Service with Drone
What is the difference between aerial photogrammetry and LiDAR?
Aerial photogrammetry and LiDAR are two very different aerial survey techniques that serve complementary purposes.
Aerial photogrammetry is based on photographic images taken by a drone. The images are georeferenced and overlaid to generate 3D models, orthophotos, and surfaces. It is ideal for detailed visual representations and architectural surveys.
LiDAR (Light Detection and Ranging) uses laser beams to measure the distances from the drone to the ground or objects with extreme precision. It produces a high-density point cloud, capable of reading even under vegetation or in poor lighting conditions. It is perfect for topographic, environmental, and geological surveys.
👉 In summary:
Aerial photogrammetry → visual survey from images
LiDAR → metric survey from laser pulses
Geomap can offer you both, integrated into a single solution.
Is it necessary to have flight authorizations?
Yes. All drone surveys must be conducted in compliance with current ENAC regulations.
Geomap works with certified pilots and registered drones, and handles obtaining permits and flight plan management directly.
For critical areas (urban centers, infrastructure, airports), we request the necessary permits in advance.
Can I use the data for my GIS or CAD software?
Yes. The data is delivered in standard and interoperable formats such as GeoTIFF, LAS, SHP, DXF, and XYZ, compatible with major GIS (QGIS, ArcGIS) and CAD (AutoCAD, Civil 3D) software.
Upon request, we can also prepare the data for integration into BIM environments or Geomap platforms.
Is the service also suitable for non-urbanized areas?
Absolutely. Aerial photogrammetry and drone LiDAR are perfect for surveying forests, agricultural areas, mountains, quarries, waterways, and rural or difficult-to-access areas.
LiDAR, in particular, allows you to read the terrain morphology even under vegetation, making it ideal for environmental and geological surveys.
What exactly will I receive at the end of the survey?
Upon completion of the project, we will deliver a complete package of processed data, including:
High-resolution orthophotos
Digital terrain models (DTM) and surface models (DSM)
Point clouds (LiDAR)
Contour lines, meshes, or sections, if requested
Technical report, metadata, geographic coordinates, and flight documentation
All files will be provided in the most commonly used formats (GeoTIFF, LAS, DXF, SHP, PDF) and ready for use.
Is it possible to combine photogrammetric surveying and LiDAR in the same project?
Yes. In many cases, we recommend an integrated approach.
We use photogrammetric sensors for visual and planimetric aspects and LiDAR sensors for altimetric and structural aspects (e.g., mapping under vegetation or uneven surfaces).
This combination ensures complete and complementary data, ideal for complex GIS, BIM, or landscaping projects.
