Frequently asked questions

A Digital Terrain Model (DTM) is a 3D representation of the terrain obtained from topographic data. It is useful for planning studies, infrastructure design and watershed analysis, among others.

A point cloud is a massive collection of points in 3D space obtained by laser scanning (LiDAR) or photogrammetry. It is used to create 3D models of terrain or structures and is fundamental in surveying, construction and conservation projects.

Contour lines represent changes in terrain height and spot heights give elevations at specific points. They are calculated from topographic surveys and are used in planning, road works and urban planning.

Topographic plans with information on elevation, the location of structures and terrain features. These reports are essential for civil engineering, construction and land planning projects.

Material volumes are measured and calculated from 3D models and LiDAR or photogrammetry data, comparing the current surface with a reference one. This makes it possible to estimate the amount of material available and extracted.

Stakeout consists of transferring the coordinates of a project from a plan or digital model to the real terrain. It is essential when building houses, roads and other infrastructure so they are built where the project says.

They make it possible to capture aerial images and panoramic views of properties, and to show the surroundings and location more clearly.

It provides high-resolution images and videos from angles that are hard to achieve by other means, improving the presentation and analysis of the project.

A timelapse captures photos at regular intervals to show change in fast motion. With a drone you can document a project’s evolution by repeating the flight from the same positions.

They provide images from heights and angles that other means cannot reach. They are useful for site inspections, construction projects or any situation where an aerial perspective adds value.

They provide data quickly, reduce exposure to risk in hard-to-reach areas and deliver images and 3D models to support decision-making.

They collect data quickly on difficult or large sites, which reduces time and resources compared with traditional methods, depending on the type of project.

They work in a range of conditions, but strong wind, rain or extreme conditions may force a flight to be rescheduled.
