From flight to result in minutes, with nothing to install. Upload the photos from your drone or smartphone and get the orthophoto and the 3D model. Measure areas and volumes in the browser and share with your team.

An isolated file does not tell the whole story.
Each piece of data enters with context
Projects, sites, objects and surveys keep their connection to the data, documents and results that belong to them.
Results ready to view
Visual information opens directly in the browser, without depending on the software installed on each computer.
Preserved history
Different dates, states and versions remain organized so it is possible to track evolution without rebuilding the past.
The right access for each person
Teams, clients and management view the information they need, in the same workspace.
