  5. What is the general form of this data set?

    Geospatial data presentation form: vector digital data

  6. How does the data set represent geographic features?

    1. How are geographic features stored in the data set?

      This is a Vector data set. It contains the following vector data types (SDTS terminology):
      • G-polygon (921)

    2. What coordinate system is used to represent geographic features?

      The map projection used is Transverse Mercator.

      Projection parameters:
      Scale factor at central meridian: 0.999941
      Longitude of central meridian: -81.000000
      Latitude of projection origin: 24.333333
      False easting: 656166.666667
      False northing: 0.000000

      Planar coordinates are encoded using coordinate pair.
      Abscissae (x-coordinates) are specified to the nearest 0.000256.
      Ordinates (y-coordinates) are specified to the nearest 0.000256.
      Planar coordinates are specified in survey feet.

      The horizontal datum used is D_North_American_1983_HARN.
      The ellipsoid used is Geodetic Reference System 80.
      The semi-major axis of the ellipsoid used is 6378137.000000.
      The flattening of the ellipsoid used is 1/298.257222.

      Vertical coordinate system definition:
      Altitude system definition:
      Altitude resolution: 0.000010
      Altitude encoding method: Explicit elevation coordinate included with horizontal coordinates

Why was the data set created?

Traffic Analysis Zones are required for long-range transportation modeling purposes.  Demographic, socio- economic, and other information can be summarized by TAZs.  This information can then be used in transportation forecast models (i.e., FSUTMS) for trip generation and distribution.

How was the data set created?

  1. Where did the data come from?

  2. What changes have been made?

    (change 1 of 2)
    This coverage was created based on the TAZ2000 feature class.  Some zones were merged, split, or re-aligned to reflect the development changes in February 2007.
