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.
Why can a high triangle count fail to improve the useful representation of a building model? A practical guide to the acquisition choices, controlled processing test, illustrative calculation, and independent checks needed for a defensible result.
How can an outlier filter remove noise while accidentally deleting useful embankment edges or narrow objects? A practical guide to the acquisition choices, controlled processing test, illustrative calculation, and independent checks needed for a defensible result.
When is reduced image resolution a justified processing choice rather than an unexamined shortcut? A practical guide to the acquisition choices, controlled processing test, illustrative calculation, and independent checks needed for a defensible result.
What tradeoff is made when dense reconstruction uses fewer neighboring views or a reduced image scale? A practical guide to the acquisition choices, controlled processing test, illustrative calculation, and independent checks needed for a defensible result.
Why can a well-aligned camera network still produce holes or noise in the dense reconstruction? A practical guide to the acquisition choices, controlled processing test, illustrative calculation, and independent checks needed for a defensible result.
How can an image network reveal that a single small group of photographs holds two large regions together? A practical guide to the acquisition choices, controlled processing test, illustrative calculation, and independent checks needed for a defensible result.
Why can thousands of tie points still leave important parts of a survey weakly constrained? A practical guide to the acquisition choices, controlled processing test, illustrative calculation, and independent checks needed for a defensible result.
How should an operator interpret a successful job report before releasing the map for measurement? A practical guide to the acquisition choices, controlled processing test, illustrative calculation, and independent checks needed for a defensible result.
Which files must be retained so a delivered orthomosaic can be investigated or reprocessed months later? A practical guide to the acquisition choices, controlled processing test, illustrative calculation, and independent checks needed for a defensible result.
When is it appropriate to resume a failed stage instead of discarding the entire project and starting again? A practical guide to the acquisition choices, controlled processing test, illustrative calculation, and independent checks needed for a defensible result.
