Office of Superintendent of Public Instruction (OSPI)School data points derived from address data provided by schools under the purview of the Office of Superintendent of Public Instruction (OSPI) to Data Management division at OSPI. The addresses were submitted to the Washington Master Address Service (WAMAS) to standardize the address formats and provide the Latitude and Longitude coordinates from the geocoding process. The address data was combined into a single address line along with the geocoded Latitude and Longitude data to enable creation of the school points based on those coordinates for each address submitted. The points were reviewed by overlaying the data points on the National Agriculture Imagery Program (NAIP) imagery provided in the ArcGIS Pro desktop software and moved to the building centroids where possible. The data points from the geo-coding process initially established the location for the school. The combined address was then populated into the PhysicalAddress field.ArcGIS FeatureLayerhttps://hub.arcgis.com/datasets/2b1977231086490a933ee8522dc85a76_0engState of Washington Geospatial Open Data PortalPublicWashington State Public Schools [Washington (State)]Web servicesWashington (State)Last Modified: 2025-12-23
