Why was the data set created?
The data in this set are intended to provide an approximate value of the UBC site class for planning purposes. Because they were derived from regional scale mapping, they are not appropriate for site-specific use.

How was the data set created?
  1. From what previous works were the data drawn?

    Data sources used in this process:
    • Rosenberg (2001)
    • Wills and others (2000)

How reliable are the data; what problems remain in the data set?
  1. How well have the observations been checked?

    All attributes created during the creation process were verified by displaying the lines in both the database and the spatial coverage, but no formal tests were performed.

  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?

    The data set is derived from the geology database compiled in this study. The original data used in this map were mapped at scales ranging from 1:2,400 to 1:125,000, with the majority at 1:62,500 scale and thus limit the resolution of this data set to 1:62,500 scale.

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

    These data are believed to be logically consistent, though no tests were performed.

How can someone get a copy of the data set?
Are there legal restrictions on access or use of the data?

Access_Constraints:
Contact the Monterey County Environmental Resource Policy Department.
Use_Constraints:
These data may not be distributed without the written permission of the County of Monterey.

  2. What's the catalog number I need to order this data set?

  3. What legal disclaimers am I supposed to read?

    This database is intended for regional planning purposes and not for site-specific evaluation. Information in this data set is preliminary in nature. This information is provided with understanding that it is not guaranteed to be correct or and conclusions drawn from such information, whether from individual use or aggregate use with other data, are the responsibility of the user.

  4. How can I download or order the data?

  5. Is there some other way to get the data?

    Contact the Monterey County Environmental Resource Policy Department for a printed copy of the erosion hazards map or for an ESRI shapefile of the erosion database.

  6. What hardware or software do I need in order to use the data set?

    For those users that do not have ArcView or ARC/INFO, ESRI provides a free GIS data viewer, ArcExplorer, that can be downloaded from their website at: <http://www.esri.com/software/arcexplorer/index.html> ArcExplorer is currently only supported on the Windows 95/98 or Windows NT platforms.
