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. 1:125000 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 scale and accuracy, see our webpage at: http://geoplan.ufl.edu/education.html.

Spatial and Attribute Information
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.

Derivation Method(s) for Data:
PRE-AUTOMATION COMPILATION :
COMPUTER HARDWARE USED : HP Workstation
OPERATING SYSTEM : UNIX
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 shapefiles. 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.
GeoPlan, during the QA/QC process included the following aspects: 1.) Removed items X and Y. 2.) Altered precision of Decimal Items to 0, since there were no fractional values. 3.) (All values contained in decimal fields were whole numbers). 4.) Dropped items w/ no values: PARAM9, PARAM10 5.) COUNTY item was dropped, and FGDLCODE and NAME items were added to correspond to old COUNTY item
Internal feature number.

FDEP
The parameter fields contain codes for pollutants and related information. Each parameter code is composed of six numerals. The first five are an EPA Pollutant Code, while the last is a Monitor Type Code. For example, in the code 424012, the 42401 signifies that the pollutant is Silicon Dioxide and the 2 signifies that the station is a state or local air monitoring station (See monitor type code descriptions below).
