Orthophoto Generation

Orthophotos are used as one important reference in GIS for mapping, feature identification and extraction. Orthophotos are prepared from aerial images by removing the tilt and relief displacement.

We at Next Geospatial do orthorectification of images by use of traditional photogrammetric method as well as from TerraPhoto specific inputs. We also have experience of doing orthomosaics from drone acquired images.

The processes that we typically follow in orthorection at Next Geospatial are:

Aerial Triangulation (TerraPhotospecific)
Prepare the DEM from LiDAR or other inputs
Add break lines for bridges and wherever required
Project triangulated aerial images to DTM.
Seam editing and color balancing
Identify hotspots and see alternate images
See for cloud or smoke in images and ensure to take images with least effect
Ensure that adjacent images are matched well to each other especially at seam lines
Import control points to ensure that images are within acceptable tolerance range.
Orthomosaic generation
Quality control and necessary corrections
Tiling and control report generation
