Fortunately for us in King County, we are well-served by a diverse network of stormwater facilities. King County’s Water and Land Resources Division (WLRD) is responsible for the stormwater system in unincorporated King County. Recently, Alison Sienkiewicz, WLRD stormwater pollution prevention inspector, wrote an article about a team that used GIS tools in the field to map and inventory the King County stormwater system to comply with requirements of the County’s Phase 1 Municipal Stormwater Permit.
Frequent users of King County iMap, the online app that provides scores of the most popular King County GIS data layers in a flexible, multi-feature, interactive map viewer, now have access to 2017 aerial orthophoto imagery as a basemap.
OpenStreetMap (OSM) is a digital map of the world to which individuals, corporations, and government agencies contribute geographic data which can then be freely used by anyone under two conditions.
Data quality at King County GIS includes processes and tools for validation of the contents of the Spatial Data Warehouse. Multiple linked automated and manual steps help ensure good internal consistency and an anomaly-free environment, both for file-system and database objects.
At King County GIS, we connect with data quality at different levels. This post is one of three introductory posts about how King County GIS is working to improve the quality of the County’s GIS data.
