Digital Photogrammetry
Overlapping imagery converted to precise 3D maps, terrain, and features.
MapSphere transforms overlapping aerial and drone imagery into accurate 2D maps, 3D models, terrain surfaces, and feature datasets through advanced photogrammetric workflows.
From aerial triangulation and 3D planimetry to breakline collection and contour generation, we produce the foundation layers for engineering and infrastructure planning.

Digital Photogrammetry — common questions
01How is photogrammetry different from LiDAR?
Photogrammetry derives 3D geometry and true-color texture from overlapping imagery — excellent for orthophotos, visual models, and open terrain. LiDAR actively measures range and penetrates vegetation better. We often combine both for the most complete dataset.
02What photogrammetric products do you deliver?
Orthophotos, planimetric feature layers, DTM/DSM/DEM, contour maps, 3D mesh models, breaklines, and volume calculations.
03Can you compute earthwork or stockpile volumes?
Yes — from a photogrammetric surface we calculate cut/fill and stockpile volumes against a base surface, with reports suitable for reconciliation.
