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

    Date: 31-Jan-2002 (process 1 of 3)
    The following steps were performed by ESRI for Data & Maps 2002: Replaced demographic and agricultural attributes with the latest from 2000 Census SF1, ESRI BIS, and 1997 Census of Agriculture. Recreated ArcView legend file (.avl) and ArcGIS™ layer file (.lyr) file. Copied projection file (.prj).

    The following steps were performed by ESRI: Extracted and generalized the features from ArcUSA 1:25M. Added demographic attributes from Summary Tape File-1A (STF-1A) data published by the U.S. Bureau of the Census based on the 1990 Census of Population. Added farm attributes from data published by the U.S. Bureau of the Census based on the 1987 Census of Agriculture. Added Pop2000 attribute from ESRI Business Information Solutions. Converted to North American Datum of 1983 (NAD83) by splitting the United States into–if present: Alaska, Hawaii, Puerto Rico, U.S. Virgin Islands–and the 48 contiguous states (including District of Columbia); converting each to NAD83; then merging them together. Recalculated any attributes based on area. Created ArcGIS™ layer file (.lyr). Created ArcView legend file (.avl). Created projection file (.prj). Ran ArcView Avenue™ request ExportClean, and created spatial indices.

    Data sources used in this process:

    • ArcUSA 1:25M
    • Census SF1
    • ESRI BIS
    • USDA Farm

    Date: 10-Oct-2002 (process 2 of 3)
    The following steps were performed by ESRI: Copied the Molokai coastline from U.S. Counties (Generalized). Created ArcView legend file (.avl), ArcGIS™ layer file (.lyr) file, projection file (.prj), and spatial indices.

    Data sources used in this process:

    • ArcUSA 1:25M
    • Census SF1
    • ESRI BIS
    • USDA Farm
    • GDT Dynamap/Census Boundaries v4.0

    (process 3 of 3)
    Dataset copied.

    Data sources used in this process:

  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?

    The geospatial part of this data set was extracted from the ArcUSA 1:25M database, then generalized. Generalizing reduces positional accuracy and the tolerance was not recorded so the positional accuracy exceeds that of the ArcUSA data set. The positional accuracy of the ArcUSA 1:25M data set is 1792 meters which is based on generalizing–to a tolerance of 500 meters–the 1:2,000,000-scale USGS Digital Line Graph (DLG) source data.

  3. How accurate are the heights or depths?

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

    After processing, the data set is checked for drawing display and number of records and file sizes compared with source materials.

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

    No duplicate features are present.
