Why was the data set created?

Provides generalized terrain and elevation information. More accurate and detailed isolines are available in the CONTOUR### layers, but the CONT layers, though less accurate, draw more quickly and their generalized quality may be more useful in some cartographic applications. The CONT series also cover a slightly larger extent beyond the King County boundary than do the CONTOUR series layers.


How was the data set created?

  1. From what previous works were the data drawn?

  2. How were the data generated, processed, and modified?

    (process 1 of 2)

    (process 2 of 2)
    Metadata imported.

    Data sources used in this process:

    • C:\DOCUME~1\LEATHE~1\LOCALS~1\Temp\xml277.tmp

  3. What similar or related data should the user be aware of?


How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

  2. How accurate are the geographic locations?

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

  5. How consistent are the relationships among the observations, including topology?


How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
