As part of this process the Survey Section maintains a Survey-Monuments database. The gis file is updated nightly and sourced from a sql database. Updates to the sql database are irregular but the gis data will be as recent as the most current version of the sql database. This data is provided for mapping purposes only.

The values indicate ‘how’ the data was collected to derive the vertical elevation. Possible values are 2=GPS; 3=Scaled from 1:24,000 USGS topographic maps; 4=Classical Differential Leveling. Note – this is different from the ORDER of the Z value, where Order refers to the accuracy of the measurement. MONUMENT Unique identification number for (Geodetic) survey control station used by the Department of Transportation in its ongoing property management, construction and road maintenance programs. WSDOT Survey Information System SQL Database MONUMENT Double 8 20 5 OBJECTID Internal feature number. Esri Sequential unique whole numbers that are automatically generated. OBJECTID OID 4 10 0 SHEET SHEET String 80 0 0 The Universal Resource Locater that takes you to the Data Sheet for the Station. Survey work done at the submeter level to centimeter level must use the coordinates shown on this sheet instead of the LAT_DD, LONG_DD values. H_METHOD H_METHOD Double 8 20 5 Method to collect the horizontal (X,Y or Northing and Easting values) for the Station. The values indicate ‘how’ the data was collected to derive the horizontal values. Possible values are 1= Classic horizontal survey; 2=GPS; 3=Scaled from 1:24,000 USGS topographic maps. Note – this is different from the ORDER of the X,Y value, where Order refers to the accuracy of the measurement. LAT_DD LAT_DD Double 8 20 9 Latitude Coordinates of the Station in decimal degrees, NAD 1983 (2011), these Coordinates are for mapping purposes only. NAME NAME String 30 0 0 Name of the Station, usually physically stamped on the station itself or the case that it is contained within. LONG_DD LONG_DD Double 8 20 9 Longitude Coordinates of the Station in decimal degrees, NAD 1983 (2011), these Coordinates are for mapping purposes only. Shape Feature geometry. Esri Coordinates defining the features. Shape Geometry 4 0 0 Points depict the locations of survey control monuments used by the Washington State Department of Transportation. Each point is attributed with locational and identification information.
