Summary

5 foot interval elevation contour lines for King County, derived primarily from 2021 lidar.

Description

Five (5) foot interval elevation contours for King County, derived primarily on 2021 lidar.

Above 1000 feet of elevation, the contour interval changes to ten (10) feet for legibility and drawing performance.The contour interval represents a best compromise between the vertical and horizontal accuracy of the source data and the need for a general use cartographic and analysis product.

The data provide a reasonable depiction of the general shape of the land, useful for determining general landform, slope, and elevation.

These contours are provided only as an interpretation of the earth's surface for reference use and do not replace the need for a professional land survey.

Attribute information

OBJECTID From ESRI	Description Internal feature number. Domain 2659999
TILE_ID From KCGISC	Description Tile identifier Domain Integer value defining township and range of tile; i.e., T22R04 would be 2204
ELEVATION From KCGISC	Description Elevation of contour isoline in feet Domain Not Found
IDX_MINOR From KCGISC	Description Indexes each elevation value as to either a 5-foot multiple only,or a 5 and 10-foot multiple. For example, the 105 foot isoline would be indexed as a 5, while a 110 foot isoline would be indexed as a 10. Domain 10
IDX_20FT From KCGISC	Description Indexes each elevation value as to whether it is a multiple of 20, cumulative multiple of 100, 500 or 100, or none of these. Useful for showing 100 foot index contours with aggregate 20's. Domain 1
IDX_40FT From KCGISC	Description Indexes each elevation value as to whether it is a multiple of 40, cumulative multiple of 200 or 1000, or not either. Useful for showing every 200 foot index contours with aggregate 40's, comparable to many USGS topographic maps. Domain 1
IDX_50FT From KCGISC	Description Indexes each elevation value as to whether it is a multiple of 50, cumulative multiples of 100, 500 or 1000 (feet), or none of these. Useful for showing generalized contours at 50 foot intervals. Domain 1
IDX_100FT From KCGISC	Description Indexes each elevation value as to whether it is a multiple of 100, a cumulative multiple of 500 or 1000 (feet), or none of these. Useful for showing generalized contours at 100 foot intervals. Domain 1
SHAPE From ESRI	Description Feature geometry. Domain Coordinates defining the features.
