A note about data scale: 

Scale is an important factor in data usage.  Certain scale datasets
are not suitable for some project, analysis, or modeling purposes.
Please be sure you are using the best available data. 

1:24000 scale datasets are recommended for projects that are at the
county level.
1:24000 data should NOT be used for high accuracy base mapping such
as property parcel boundaries.
1:100000 scale datasets are recommended for projects that are at the
multi-county or regional level.
1:125000 scale datasets are recommended for projects that are at the
regional or state level or larger.

Vector datasets with no defined scale or accuracy should be
considered suspect. Make sure you are familiar with your data
before using it for projects or analysis. Every effort has been
made to supply the user with data documentation. For additional
information, see the References section and the Data Source Contact
section of this documentation. For more information regarding

DATA LINEAGE SUMMARY:
GeoPlan received county wide parcels datasets from the
Florida Department of Revenue (FDOR) in 2007 via DVD. 

The datasets were in shapefile format, and in the following projections: 
State Plane Projection NAD 83, Feet (East, North, and West). 
The datasets were projected to FGDL Albers HPGN.

Process for dissolving parcel polygons based on decade of actual year built:

- For each county, FDOR tables containing the Parcel Actual Year Built 
data were joined to the shapefile, and a new field representing 
Actual Year Built [AYRBLT] was populated based on the table information.

- The parcel polygon boundaries were then Dissolved 
(as single part features) based on the Actual Year Built [AYRBLT] field.

- The shapefiles were then merged together based on the FDOT 
District that each County fell in, creating seven district wide shapefiles.

- A decade lookup table was created to represent decades between 
1600 - 2007. The lookup table had 2 fields: [YEAR] for individual year 
between 1600-2007, and [DECADE] for unique decade identification 
number. The decade lookup table was then joined to the Dissolved 
District shapefiles.

- Another single part Dissolve was run on the shapefiles based on 
the decade.

- The [DECADE] field was then renamed [YB_DECADE].

- The final shapefile represents polygons of parcels which 
structures/ buildings were originally built in the same decade.

- Several other fields were added to the attribute table:
   [AUTOID] - A GeoPlan Center Internal Feature number
   [DESCRIPT] - Based on [YB_DECADE]
   [FGDLAQDATE] - The date FGDL acquired the original data from the Source.
