FEATURE ATTRIBUTE TABLES CODES AND VALUES:

Item
Item Description
OBJECTID Internal feature number.

Shape Feature geometry.

STATUS Data attribute inherent to the ESRI shapefile format, (whether it was matched or not).ESRI

SCORE ESRI item which denotes the score with which the address was matched to a feature in the reference data. Records markerd with an "0" have not been GeoCoded, these records have another type of spatial reference source, see source field for more information.

SIDE ESRI item which denotes the side of the street to which the address was matched (for geocoding service styles that can match an address to a particular side of a street). Records markerd with an "*" have not been GeoCoded, these records have another type of spatial reference source, see source field for more information.

MATCH_ADDR ESRI item which denotes the full street layer address to which the address was matched (May be different from address listed in original database).

FILE_ No description

PRJ_NUMBER Project number of MHP.

RANK The project description.

NAME Name of MHP.

COUNTY Name of county where MHP is located.

STREET Street of MHP.

CITY City of MHP.

STATE State of MHP.

ZIPCODE Zipcode of MHP.

LOTS The number of lots within the MHP.

USNG_FL_1K Facility's 1-kilometer United States National Grid (USNG) address. The USNG is an alpha-numeric reference system based on the UTM coordinate system and is similar to the Military Grid Reference System. Use of the USNG ensures a uniform grid mapping and positional reporting system for search and rescue, emergency planning, response, and recovery.

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.
-------------------------------------------------------------------
Under Chapter 119, Florida Statutes, the Department of Business and 
Professional Regulation (DBPR) is required to make available for 
inspection and copying any public record regardless of physical format, 
which is not otherwise exempted from public access by general law. 
To fulfill this obligation, the DBPR provides copies of electronic 
records to the public through free download.

DBPR is only required to provide data in the format in which it is 
maintained and, as a result, does not provide paper copies of this 
information. In addition, the DBPR is not required to reformat its 
records to meet a requestor's particular needs.

Section 119.01(2)(b), F.S., requires only that the agency provide
electronic data in some common format such as, but not limited to, 
the American Standard Code for Information Interchange (ASCII) text 
format. As, the download files provided by DBPR are formatted as 
ASCII text, quote/comma delimited.

The data was created to serve as base information for use in GIS systems 
for a variety of planning and analytical purposes

The Florida Geographic Data Library is a collection of Geospatial Data
compiled by the University of Florida GeoPlan Center with support from
the Florida Department of Transportation. GIS data available in FGDL is
collected from various state, federal, and other agencies (data sources)
who are data stewards, producers, or publishers. The data available in
FGDL may not be the most current version of the data offered by the
data source. University of Florida GeoPlan Center makes no guarantees
about the currentness of the data and suggests that data users check
with the data source to see if more recent versions of the data exist.

Furthermore, the GIS data available in the FGDL are provided 'as is'.
The University of Florida GeoPlan Center makes no warranties, guaranties
or representations as to the truth, accuracy or completeness of the data
provided by the data sources. The University of Florida GeoPlan Center
makes no representations or warranties about the quality or suitability
of the materials, either expressly or implied, including but not limited
to any implied warranties of merchantability, fitness for a particular

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
scale and accuracy, see our webpage at:

DATA LINEAGE SUMMARY:
Mobile home locations and information were obtained from the 
online MyFlorida site in February 2010 from
http://www.myfloridalicense.com/dbpr/sto/file_download/layout/ctmh.html.
GeoPlan downloaded this data in .CSV format and converted it to a 
dbf. Upon conversion to a DBF table the field names were truncated to 
adhere to the DBF syntax. The dbf was then geocoded against a statewide 
2009 Tele Atlas Streets dataset and converted into a shapefile with the 
FGDL Albers HPGN map projection. (See "Map Projection Parameters" below). 
After geocoding the following steps were applied.

- Locations receiving a matched score below 80 (approx 750) were reevaluated using 
  Google Earth. Locations' addresses that were successfully located were modified  to 
  reflect the correct address using the geocode rematch tool in ArcGis. 
- 118 records were unable to be matched and removed from the database.
- Matched points were then moved to the corresponding parcels by matching the 
  owner or  address in the parcel database. Points not able to be matched to a parcel 
  remained at their original geocoded location.
- Four points were removed due to evident changes in the land use via Google Earth. 
  These locations were:
 1) College Park Leisure Homes, 850 Maury Rd, Orlando, FL 32801
 2) Page Mobile Village, 4944 Cleveland Ave, Ft. Myers, FL 33907
 3) Mockingbird Village Mobile Home Park, 335 Mockingbird Lane, Lantana, FL 33462
 4) Pine Grove Trailer Park, 810 N 4th St, Lantana, FL 33462
- Added and calculated LAT_DD, LONG_DD, and USNG_FL_1K fields.
- Added DESCRIPT field based on NAME.
- Added FLAG and UPDATE_DAY fields.
- Updated Flag field for points that were moved to the parcel
- Added FGDLAQDATE based on the date FGDL acquired the 
  data from the Source.
