 "snippet": "Statewide polyline feature class of Adopt-A-Highway (AAH) sites across all 12 Caltrans districts, merged into a single layer for display in the statewide AAH web map with district toggle/filter. Each feature is a highway segment along the State Highway Network that is available for adoption, adopted, vacant, or not adoptable. Geometry is generated by linear referencing each segment's begin and end postmiles along the SHN centerline (SHN_lines) via the Caltrans LRS measureToGeometry operation; each travel direction on a divided highway is placed on its own alignment. The published status field (Status_Pub, aliased 'Status': Adopted, Available Pending Site Review, Vacant, Not Adoptable) drives the map symbology. Location and status depend on the source Adopt-A-Highway database; users should verify critical sites against the district AAH coordinator's records.",
 "description": "The AAH_all_Highway feature class displays Adopt-A-Highway sites as highway segments for the entire California State Highway Network, merged from all 12 Caltrans districts into one statewide layer. It is produced by the AAH application-to-feature pipeline, which ingests each district's GIS join query exports (D##_qry_GIS_Join_EN1 and _WS1), drops personally identifiable applicant contact fields, and generates line geometry by linear referencing each site's begin and end postmiles along the State Highway Network centerline (SHN_lines) using the Caltrans LRS measureToGeometry REST operation.\n\nEach travel direction on a divided highway is derived from the source direction and placed as a separate feature on its own alignment; directions are never merged. The map status class (Status_Pub, aliased 'Status') is derived by the pipeline's reclassification step from the source adoption status, with 'Vacant (NSR)' promoted to 'Available Pending Site Review'. The published schema is a curated subset for public display: feature key (id_AHH_Join), district, county, route, begin/end postmile and postmile span (pm_span_mi), direction, city, begin/end postmile landmark descriptions, location type, maintenance region, and the derived public status (Status_Pub, aliased 'Status'). Source applicant, contact, and group fields are not included.\n\nSites with real postmile length (pm_span_mi greater than zero) are placed in this layer; single-postmile 'other location' sites are placed in the companion AAH_all_other_loc point layer. Approximately 99.4% of source rows are successfully placed statewide. The layer is establish-then-update: the schema is created on the first run and subsequently truncated and reloaded. Spatial reference follows the SHN_lines source; confirm before publishing.",
