FEATURE ATTRIBUTE TABLES:

Datafile Name: AIRMON_JUL05.DBF

FEATURE ATTRIBUTE TABLES CODES AND VALUES:

Item	Item Description
OBJECTID	Internal feature number.
COUNTY	Three digit odd number assigned to each county; used in AQS and AIRS codes to identify location of monitoring sites. Even numbers are assigned when a county changes its name (eg Miami-Dade).
SITE_ID	AIRS number of the site; it is composed of the 3 digit county code and the site number
AGENCY	Code assigned to the agency that reports the data for the site. F = State G = County H = City J = Private N = Federal
ADDRESS	City, local area, or institution at which site is located. Often chosen for its to site operators
PARAM1	The 5-digit number assigned to pollutants and other data collected at the monitoring sites. 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 SO2 and the 2 signifies that the station is a state or local air monitoring station. Monitor Type Code: 1 NAMS National Air Monitoring Station, 2 SLAMS State and Local Air Monitoring Station, 3 Special Purpose. EPA Pollutant Codes: 11101 = Total Suspended Particles 12128 = Lead 42101 = Carbon Monoxide 42401 = Silicon Dioxide 42601 = Nitrogen Oxide 42603 = Other Oxides of Nitrogen 44201 = Ozone 61101 = Wind Speed 61102 = Wind Direction 61103 = Vector Wind Speed 61104 = Vector Wind Direction 81102 = Particulate Matter < 10 microns
PARAM2	See PARAM1
PARAM3	See PARAM1
PARAM4	See PARAM1
PARAM5	See PARAM1
PARAM6	See PARAM1
X	X coordinate of point
Y	Y coordinate of point
DESCRIPT	FGDL added field based on full description of county code in COUNTY field.
FGDLAQDATE	FGDL added field based on date downloaded from source.
SHAPE	Feature geometry.
AUTOID	Unique ID added by GeoPlan

USER NOTES:

This data is provided 'as is'. GeoPlan relied on the integrity of the original data layer's topology

This data is provided 'as is' by GeoPlan and is complete to our knowledge.

GeoPlan relied on the integrity of the attribute information within the original data.

The original file with over 500 sites contained all the sites that monitored at one time or another. This most recent file only contains the sites that monitored at the time the file was submitted. Sites are opened and closed frequently as needs, conditions, rules, or property policies change. Site locations were derived using two different methods. Most of the sites were derived by GPS units, and the rest through interpolation from 1:24,000 USGS 7.5' Quad maps. Therefore, these locations are for illustrative purposes only and should not be used for legal determinations.

Ambient air monitoring data are provided to the EPA, to meet federal requirements, and to communicate air quality to other levels of government, air monitoring professionals, researchers, medical professionals and the public to ensure that adequate information regarding the quality of the air is available to justify modifications in planning, development, and personal behavior.

THE DATA INCLUDED IN FGDL ARE 'AS IS' AND SHOULD NOT BE CONSTRUED AS LEGALLY BINDING. THE UNIVERSITY OF FLORIDA GEOPLAN CENTER SHALL NOT BE LIABLE FOR ANY DAMAGES SUFFERED AS A RESULT OF USING, MODIFYING, CONTRIBUTING OR DISTRIBUTING THE MATERIALS. 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.

DATA LINEAGE SUMMARY:

Locational data was originally obtain through interpolation from 1:24000 USGS quad sheets, but most of this data has been updated using GPS units. The data ate maintained on EXCEL spread sheets, which are converted to data base files and used in ARC GIS where the LAT/LONS are converted to ALBERS coordinates. Updates of GPS data are available every two years. Process Date: 199708 Obtained MS Excel spreadsheet with latitude, longitude information of 138 air monitoring sites from Nancy Shelton (DARM) . Imported this spreadsheet as a table into a MS Access database and used Access table in ArcMap to create a shapefile using the Table2Point tool. This shapefile was then inserted into ArcSDE. Process Date: 20050721 This dataset was downloaded by the GeoPlan Center from the FDEP website (http://www.dep.state.fl.us/gis/datadir.asp) on 08/03/2006. When received the data set was in the following projection: Albers NAD 83 HARN. - Added the field DESCRIPT based on full description of county code in COUNTY field. - Added the field FGDLAQDATE based on date downloaded from source. - Upcased all text in the attribute table. - Data set was renamed airmon_jul05 from ambient_air_monitoring_sites - Deleted fields OFFICECODE, PARAM7, PARAM8, PARAM9, PARAM10 as they contained no data. Process Date: 20070117
