Why was the data set created?

For creating a variety of GIS based mapping products requiring hydrology, such as site plans, stormwater analysis, etc.


How was the data set created?

  1. From what previous works were the data drawn?

    To be determined (source 1 of 1)
    L. Robert Kimball & Associates, 2002.

    Online Links:

    • www.lrkimball.com

    Type_of_Source_Media: Color aerial photograph film transparency
    Source_Scale_Denominator: Unknown
    Source_Contribution: L. R. Kimball created the entire dataset

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

    Date: 2002 (process 1 of 1)
    Derived from orthophotos

    Data sources used in this process:

    • \\maps\d$\Program Files\gis_online_default\gisonline\metadata\water bodies.xml

  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?

    Accuracy was determined by the contractor and is the same as when the data was received.

  2. How accurate are the geographic locations?

    The accuracy of the digital data is tested by manual visual comparison with the source images in the initial quality control process upon acceptance.

  3. How accurate are the heights or depths?

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

    All photo-interpretable features are mapped.

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

    Insofar as these features were derived directly from aerial imagery, it is assumed that each feature is a faithful positional representation of its parent feature in the imagery.


How can someone get a copy of the data set?

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