GOVERNMENT BUILDINGS 2005

This dataset is a combination of government addresses from the
Yellow and Super Pages online.

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.

Spatial and Attribute Information

Government building locations were obtained from the online Yellow and 
Super Pages in 2005. GeoPlan downloaded this data in text file format and
converted it to a dbf.  The dbf was then geocoded against ARC
Logistics Route GDT Roads and converted into a shapefile with the
FGDL Albers HPGN map projection.

 Process Steps for Yellow Pages data:
-The addresses were geocoded against ARC Logistics Route GDT Roads
 Shapefile created using FGDL Albers HPGN map projection (See "Map
 Projection Parameters" below).
-The two datasets were combined and duplicate records were removed.

(A5) Some Information from the 2004 geocoded data set was 
retained; this data was retained for three reasons: 

 1. The Yellow Pages and Super Pages Online are paid 
advertising sites, some facilities may wish to discontinue 
their advertising with those companies but they may still 
exist at that address/location (i.e. Churches etc). 
 2. The address might have changed slightly (i.e. suite 
number, building number, or zip code) which may have 
affected the addresses ability to be geocoded with the 
2005 GDT roads dataset. 
 3. The facility no longer exists. 

Because facilities in reasons one and two may still exist 
in the real world all the 2004 geocoded features that were 
not reproduced in the 2005 geocode update were re-geocoded 
against the 2005 GDT roads dataset.  These facilities were 
then added to the 2005 geocoded dataset. Facilities that 
are part of this scenario are represented with a value of 'NIN' 
(Not In New) in the field called FLAG.

-Added DESCRIPT field based on NAME
-Socio-Cultural Effect data fields and definitions were added. 
 FLAG, UPDATE_DAY, AUTOID, NAME, ADDRESS, CITY,
 OPERATING, OP_CLASS, HOURS, SPECIAL, YR_BUILT,
 COMMON_USE, USE, FGDLAQDATE.
-For facilities that previously existed the permanent auto 
 identification number [auto id] was carried over from the
 2004 SCE base data to the 2005 SCE updates. For new 
 facilities autoids were created.
-Total Records = 10522
