Survey Monument Database

The database is a set of entities and attributes as referenced to individual geographic locations, hereafter referred to as "Point". Each individual Point has a location relative to all other points in the database as referenced to a coordinate grid. The relative location of the points as represented in this database correspond to the physical or determined locations of Survey Control Monumentation.

Attribute values of each point may contain accuracy data, physical descriptions on the monuments, descriptions for retracement and recovery, horizontal and vertical reference datum's, dates of recovery, determination, origin of data values, and methods used for value determination.

Feedback and data questions should be sent to: monument@wsdot.wa.gov
