Sewnode.shp is a point shape file which contains the City of Bellingham's Sewer Node data for sewer tees and caps.
The Point Attribute Table stores the node type, number, coordinates, source, etc. Note: Only item fields of interest are shown in table below. All internal fields have not been described.
| Item | Type | Length | Description |
|---|---|---|---|
| fitt-type | Letter designation for node type: T = Tee; C = Cap |
||
| unitid | User assigned unique number for each node. | ||
| easting | GPS collected easting coordinate of node. | ||
| northing | GPS collected northing coordinate of node. | ||
| elev | GPS collected elevation of node. | ||
| map# | Quarter section number. | ||
| accuracy code | Code corresponding to a range of measurements of accuracy of actual location of asset versus shown placement of node on map. | ||
| source code | Code representing the source of the information used to place the node on the map. | ||
| project# | City construction project number from which the node was installed. |
The coverage was originally (1991) digitized in AutoCAD from 1:1200 Sewer map pages. The digitized quarter section drawings were adjusted to known section and quarter section coordinates. In 1995, the AutoCAD maps were again adjusted to best fit with surveyed centerline data. In 1996, the AutoCAD information was converted to ArcInfo by city staff. Since 1998, all sewer assets have been located using survey grade GPS. The shape file is continually updated and enhanced as we receive new source data and correction information.
