Purpose

The Orthophoto workflow reviews geospatial raster products for a mission. It supports a primary orthophoto source, DSM and DTM elevation sources, derived COG outputs, hillshade, ground bands, raised features, metadata inspection, activity, recovery, and a georeferenced viewer.

Source Slots

Primary orthophoto

The main georeferenced raster source. Accepted formats include GeoTIFF and ZIP packages depending on upload policy.

DSM source

Digital surface model source used for surface elevation, raised features, and surface analysis.

DTM source

Digital terrain model source used for ground reference and terrain comparison.

Outputs

Orthophoto COG for efficient map viewing.
DSM COG and DTM COG for elevation-backed products.
Hillshade for visual terrain relief.
Ground Bands for terrain classification and ground-level interpretation.
Raised Features for height-above-ground and surface-object interpretation.
Metadata and QA checks for projection, pixel size, state, and processing reliability.

Workspace Sections

The workspace combines source cards, output cards, pipeline stages, storage inventory, activity and recovery, and viewer launch actions. It is both an operator console and a reviewer entry point.

QA Checks

Orthophoto QA should verify that the raster has a usable projection, reasonable pixel size, valid extent, readable metadata, and complete derived products. Elevation outputs should be checked against whether the DSM and DTM sources are available and compatible.
