imagery-raster-analysis

Use this sub-skill for imagery and raster workflows that center on:

• ImageryLayer and image-service access
• raster functions and function chains
• raster analytics tools and persisted raster outputs
• multidimensional rasters
• orthomapping project, image collection, GCP, DSM, and orthomosaic workflows

Do not use this sub-skill for:

• learned model training or inference (deep-learning)
• map display basics or widget setup (mapping-location-services)
• feature layer / SEDF / spatial analysis (features-dataframes-analysis)

Quick routing

1. If you already have an image-service URL or imagery item, start with ImageryLayer.
2. If you need on-the-fly visualization or band math, use raster functions.
3. If you need server-side processing, saved outputs, or large data, use raster analytics.
4. If you need UAV image collections, sensor models, seamlines, DSM/DTM, or orthomosaics, use orthomapping.
5. If the target GIS lacks raster analytics or orthomapping support, stop and explain the missing service.

Preflight

• Confirm the target GIS or portal connection is authenticated.
• Check arcgis.raster.analytics.is_supported(gis) and arcgis.raster.orthomapping.is_supported(gis) before server-side work.
• Inspect ImageryLayer.properties.rasterFunctionInfos before applying a named function.
• Use unique output_name values for persisted raster jobs.
• Treat future=True and other async outputs as jobs or result objects, not immediate rasters.
• In credential-free environments, keep to imports, signatures, and static reasoning only.
