Process Description:
Data is collected as part of an on-going field verification process of all sites and buildings used by WSDOT. One set of x, y coordinates are collected for each location using a handheld GPS device. For sites with a definitive boundary and entrance, coordinates are acquired at the main entrance. For sites without a definitive boundary or other facilities, coordinates are collected at the approximate centroid of the property. Data is retained in the WSDOT Computer Aided Facility Management (CAFM) System. All site data including coordinates are retained in the Sites table. Building and room area data are retained in separate tables, which are related to the site table. Queries and views are used to capture and collate pertinent data from these tables for the GIS Workbench. Areas by type for each building are a total calculation based on the cataloguing of individual rooms within each building.
