USER NOTES:

LIMITATIONS OF THE DATA / WARNINGS TO THE USER :

Site locations were derived using two different methods and most of the sites
were derived through interpolation from 1 : 24,000 USGS 7.5' Quad Sheets. See
"Data Lineage Summary" description below.
A note concerning data scale:
Scale is an important factor in data usage. Certain scale datasets are not
suitable for some project, analysis, or modelling 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.

1:250000 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 analyses. 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 scale and accuracy, see our web pages at:

http://www.geoplan.ufl.edu/education.html
 

FGDL QUALITY ASSURANCE STATUS:

-Removed items X and Y.
-Altered precision of Decimal Items to 0, since there were no fractional values.
(All values contained in decimal fields were whole numbers).
-Dropped items w/ no values: PARAM9, PARAM10
-COUNTY item was dropped, and FGDLCODE and NAME items were added to correspond to
 old COUNTY item

DATA LINEAGE SUMMARY:

Dataset was downloaded by GeoPlan in shapefile format from FDEP
(http://www.dep.state.fl.us/gis/datadir.asp) Converted the
field COUNTY to FGDLCODE equivilent attribute labels, then deleated COUNTY field.
Added the field NAME to define the attributes of the FGDLCODE field.

The dataset's prior history is below.

    GIS/MAPPING SOFTWARE AND VERSION USED : ArcView 3.0a + ARC/INFO 7.1.1

Explanation of Procedures Used to Transform the Data:

    Locational data was obtained by two methods.  Sites in Broward and
Hillsborough Counties were obtained using a Trimble PRO/XL GPS unit with
differential correction.  The rest of the sites were derived through
interpolation from 1 : 24,000 USGS 7.5' Quad Sheets.
    Original spreadsheet of Ambient Air Monitoring Sites contained sites in
both UTM Zone 16 and UTM Zone 17, so records were separated into two tables.  In
ArcView 3.0a, the tables were used to create event themes which were converted
to shape files.  In ARC/INFO 7.1.1, the shape files were converted to coverages
using the SHAPEARC command, each were projected from their respective UTM Zones
into DEP's Albers projection.  Now in a common projection, the two coverages
were merged using the APPEND command.
