THE DRONE COLLAB JOURNAL
Explore practical photogrammetry, GNSS, IMU, GIS and remote sensing methods. Technical explanations, worked examples and field checks for the people turning aerial photographs into usable maps.
When can dividing a large survey make processing manageable without creating inconsistent neighboring products? A practical guide to the acquisition choices, controlled processing test, illustrative calculation, and independent checks needed for a defensible result.
What should be investigated when a job approaches its memory limit before producing a dense surface? A practical guide to the acquisition choices, controlled processing test, illustrative calculation, and independent checks needed for a defensible result.
Why is photograph count alone a weak predictor of processing demand for two different mapping missions? A practical guide to the acquisition choices, controlled processing test, illustrative calculation, and independent checks needed for a defensible result.
