Photogrammetry

Filtering Point Clouds without Erasing Real Structures

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.

Cloud processing

Downscaling Images while Preserving Required Map Detail

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.

Photogrammetry

Understanding Depth Map Quality and View Selection

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.

Photogrammetry

Separating Sparse Alignment from Dense Surface Quality

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.

Photogrammetry

Using the Camera Connection Graph to Find Weak Links

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.

Cloud processing

Reading a Processing Report as a Diagnostic Record

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.

Cloud processing

Planning Storage Retention for Reproducible Mapping

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.

Cloud processing

Resuming Failed Processing with an Auditable Run Record

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.

Cloud processing

Scheduling Concurrent Jobs without Resource Contention

Why can submitting several reconstructions at once make all of them finish later on a shared processing system? A practical guide to the acquisition choices, controlled processing test, illustrative calculation, and independent checks needed for a defensible result.

Cloud processing

Choosing Chunk Overlap from Scene Geometry

How much shared coverage is needed between processing chunks when the boundary crosses tall vegetation or structures? A practical guide to the acquisition choices, controlled processing test, illustrative calculation, and independent checks needed for a defensible result.
