The Analysis | Geocoding | Geocode
command 
allows you to assign XY coordinates
to known street addresses. To geocode in MapViewer,
you need a location file and an address file. Selecting the Geocode
command opens the Assign Latitude/Longitude
Coordinates to U.S. Address or Street Intersection dialog.
The Assign Latitude/Longitude Coordinates to U.S. Address or Street Intersection dialog contains data source options, input format options, and output options for geocoding.
Set options for geocoding in the Assign Latitude/Longitude Coordinates to U.S. Address or Street Intersection dialog.
Geocode Data
Select the geocoding location file from the Geocoding data source list. The geocoding data file contains the coordinate locations of the addresses you wish to match.
If you purchased MapViewer on CD, the Census-based Golden Software [.STR] street data files are available on the United States Street Data CD. If you purchased MapViewer with the download-only option, contact Golden Software to order the United States Street Data CD.
You can also select Dynamap/2000 in GDT format (ASCII) [.TS1] produced by Geographic Data Technology or Dynamap/2000 in ArcView format [.SHP] produced by Geographic Data Technology. These location files are available for a fee from Tele Atlas via Tele-Mart. Please note that if you use files in the GDT format, all files including the [.TS1] and [.TS2] are needed.
Geocoding Data Path
Set the geocoding data path in the Specify
the folder path containing all [geocode data source type] subfolder and
files box. Type the path or use the 
button to
browse to the path.
This box should contain the root path. For example, if you have several states listed in a folder:
C:\ Data\Street Data\CO
C:\ Data\Street Data\NM
etc.
you can enter C:\ Data\Street Data as the folder path. This would allow you to geocode addresses in Colorado and New Mexico in one session.
Input Columns
Select the column containing addresses in the Address list. If the entire address is located in one column, do not check the City, state, and ZIP code are in separate columns box. The address must appear as <street number> <street name>, <city name>, <state name> <ZIP code>.
If the address, city, state, and ZIP code information are located in separate columns, check the City, state, and ZIP code are in separate columns box and select the columns in the City, State, and ZIP code lists.
If the address has two lines, check the Address 2 box and select the appropriate column from the list.
Note that P.O. Box addresses are not supported.
Output Columns
Select the columns to place the latitude/longitude information from the Longitude and Latitude lists. Check the Result string box and then select a column to add a column containing information about the processing of each address such as Exact match, Street not found, etc.
Column Headers
Check the First row as label box if the data contain headers in the first row and if you would like the newly created columns to contain headers.
Interactive Geocoding Dialog
Check the Display Interactive Geocoding dialog when necessary to display the Interactive Geocoding dialog. This dialog is used to show "problem" addresses and resolve them.
Street Numbers
If there is not an exact match for the street number in the geocoding data source file, check the Use closest address number if exact match can't be found box to use the closest available street number.
ZIP Code Centroids
If an address cannot be matched because it is in an invalid format or the geocoding data file cannot be found and you would like to plot the address at the ZIP code's centroid, check the Assign ZIP centroid to record with wrong address format or with no geocoding data file if possible box.
Note that this option will not assign ZIP code centroids to addresses when the street name is not found. Use the Geocode Above Records And Assign ZIP Centroid If No Match button in the Interactive Geocoding dialog to assign ZIP code centroids to records with Street not found errors.
Address Abbreviations
Click the Address Abbreviation Editor button to add address variations, such as St for Street; remove punctuation from addresses; and truncate items such as suite numbers from addresses.
