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
- If you already have an image-service URL or imagery item, start with
ImageryLayer.
- If you need on-the-fly visualization or band math, use raster functions.
- If you need server-side processing, saved outputs, or large data, use raster analytics.
- If you need UAV image collections, sensor models, seamlines, DSM/DTM, or orthomosaics, use orthomapping.
- 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.
