About this course
An aerial mosaic should read as one coherent image, even when its source photographs differ. Kevin JONES demonstrates a Geomatica workflow that moves from project preparation and block adjustment to mosaic editing, color balancing and final export.
The 36-minute listing contains six lectures across four sections. It includes a multi-user editing setup and post-export touch-ups, making it a focused workflow demonstration for learners already familiar with aerial imagery.

Skills you’ll gain
- Describing the preparation of an aerial-image mosaic
- Understanding the role of block adjustment and registration
- Following a staged color-balancing and editing process
- Recognizing collaborative editing and export checkpoints
Prior knowledge of ground control, tie points, cutlines and other photogrammetric concepts is expected. This is not a first introduction to maps or an assurance that a learner’s output will meet survey accuracy requirements.
The demonstration uses licensed Geomatica desktop software. Watching the course is free, but reproducing its exact interface and processing steps requires separate access to that software; no permanent free license is included. The referenced sample imagery is described as available for non-commercial instructional use, and its terms and download availability should be checked before use.
For a free route into general raster and geospatial practice, QGIS is an open-source option. It is not a drop-in replacement for this proprietary workflow or its collaborative mosaic editor. The instructor estimates two to three hours with practice, while the published recorded duration is 36 minutes; individual completion time will vary.
QGIS downloads: a free geospatial tool for related practice, with a different workflow.
