USER NOTES:
This dataset is a combination of petroleum tanks oriented addresses from the Florida Department of Environmental Protection online. Tank Facility - All Locations & LatLong Information (by County) [October 6, 2003] Excel spreadsheet of the facilities registered with the Department and tracked for active storage tanks, storage tank history, or petroleum cleanup activity. Information includes facility identification number, site location information with latitude/longitude, and facility type and status. Data is taken from the Storage Tank & Contamination Monitoring database. FLORIDA DEPARTMENT OF ENVIRONMENTAL PROTECTION STORAGE TANK AND CONTAMINATION MONITORING DATABASE CODES LIST ftp://ftp.dep.state.fl.us/pub/reports/codes/fs_codes.pdf What is Geocoding? Geocoding is term used to describe the act of address matching. Geocoding is the process of finding a geographic location (x, y point) for an address (such as street number and name, city, state, and ZIP Code) on a map. Geocoding is based off the typical address scheme for the US, in which one side of the street contains even house numbers while the other side of the street contains odd house numbers. The geocoding process uses an algorithm to find the geographic location of addresses. First, a street segment is identified using the zip code and street name. Next, the geographic location of the address is matched using the building number to determine how far down the street and on which side of the street the building is located. Geocoding Accuracy The locational accuracy of geocoded addresses may vary from urban to rural areas due to the algorithm used to generate the geographic locations of addresses. The algorithm assumes that the size of parcels are equivalent along a road route. This assumption tends to be more consistent in urban areas, where the size of parcels vary less than in rural areas. Consequently, the results of geocoded addresses in urban areas are usually more reliable than those in rural areas. For example, the locational accuracy of rural addresses can be slightly off because some parcels along a rural route may be 15 acres while others may be 2.5 acres, but the geocoding algorithm assumes that the addresses are distributed evenly along the route. 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 multicounty 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.

FGDL QUALITY ASSURANCE STATUS:
Process Steps for Florida Department of Environmental Protection -Petroleum Tanks Locations: -Searched for petroleum tanks locations at http://www.dep.state.fl.us/waste/quick_topics/database_reports/pages/stcm/storagetank/stcm_allll.htm -Merged all county spreadsheets in to one excel spreadsheet file. the .xls file was then formatted so that it could be converted to a database file format. -For records containing Full Latitude and Longitude coordinates these records were mapped spatially based on there x and y location in ArcMap. All other locations where mapped through geocoding. -The addresses were geocoded against ARC Logistics Route GDT Roads Shapefile created using FGDL Albers HPGN map projection (See "Map Projection Parameters" below).

DATA LINEAGE SUMMARY:
Petroleum Tanks locations were obtained online from the Florida Department of Environmental Protection in 2003. GeoPlan downloaded this data in excel file format and converted it to a dbf. The dbf was then either mapped based on the tanks latitude and longitude coordinates or if this informatin was incomplete then the data was geocoded against ARC Logistics Route GDT Roads and converted into a shapefile with the FGDL Albers HPGN map projection. (See "Map Projection Parameters" below).
