From reality to digital model.
EPC provides a comprehensive service ranging from survey design to acquisition, processing, and delivery of terrestrial laser scanner, photogrammetric, and LiDAR data across various application sectors.
What we offer
EPC specializes in using modern topographic survey technologies and processing collected data. Our range of instruments allows us to autonomously conduct surveys of objects and surfaces of various sizes, from small architectural details, buildings, and structures to entire land areas, including riverbeds, quarries, landfills, and slopes.
Depending on the context and work objective (size, level of detail, required accuracy), EPC employs targeted survey strategies, effectively using one or more instruments. Over the past few years, EPC has specialized in topographic surveys using terrestrial laser scanners, LiDAR, and terrestrial and aerial photogrammetry techniques.
The ability to conduct surveys from above allows us to easily overcome physical obstacles, drastically reducing work times and addressing various environmental contexts. EPC currently owns one of the best vehicles on the market and is recognized among ENAC operators for operating in non-critical scenarios.

SURVEY STRATEGIES
Continuous Morphology Survey
Over the past ten years, the approach to discrete surveying (single points) has been supplemented and, in many cases, replaced by continuous surveying. This method reconstructs geometries and shapes not schematically but in a way that fully adheres to reality. EPC srl has specialized in these survey methods, employing the most efficient solutions and using one or more instruments in combination for each project.

One Tool for Each Project
The choice of equipment depends on the specific context of the survey. On one hand, drones offer high productivity, allowing extensive areas to be covered with centimeter-level precision in a short amount of time. On the other hand, terrestrial laser scanners provide sub-centimeter accuracy and are preferable for detailed surveys.

PHOTOGRAMMETRY AERIAL AND TERRESTRIAL
Explore the World with Millimeter Precision
Aerial photogrammetry is a technique that utilizes photographs taken from aircraft or drones to create maps, 3D models, and other spatial representations of the terrain. It is used in cartography, topography, and environmental monitoring. Terrestrial photogrammetry, on the other hand, involves photographs taken from the ground to measure and model objects or surfaces. It is commonly used in architecture, archaeology, and engineering to document and analyze structures and sites.
