Production & Use of 3D Deliverables
The high density of Geokali’s 3D models allows the extraction of highly accurate orthophotos, offering exceptional visual clarity and detail.
From the 3D models, we generate plans, elevations or sections at the desired location. A vectorised section line is then produced and overlaid on the orthophoto. The whole set is compiled into a DWG file, providing a basis for architectural drawing or condition assessment.
To standardise this production, a major internal automation effort has been carried out. File structures, naming conventions and formats have been made reliable and consistent, while remaining easily adaptable to the needs of each team.
The 3D model itself is made available through a web platform, accessible from a smartphone or standard workstation, with no loss of quality.

Geokali also produces architectural drawings for historic monuments based on its 3D extractions.
