ZCTAs are a new statistical entity developed by the U.S. Census Bureau for tabulating summary statistics from Census 2000. ZCTAs are generalized area representations of U.S. Postal Service (USPS) ZIP Code® service areas. They represent either USPS five- or three-digit ZIP Code areas. The term ZCTA was originated to differentiate between true USPS ZIP Codes and these approximations.
How to Use the Address Finder
This feature is designed to quickly map a specified street within a county containing a ZIP Code Tabulation Area (ZCTA).
After entering the street name and ZIP Code, the Address Finder creates a list of matching street names for the county or counties containing the ZCTA and presents them in the MARPLOT® Search Collection window. Select
the street and click on either the Addresses or Intersection button to identify the appropriate street segment to be mapped. Then click either the Show on Map or Show on Map & Zoom to position your map focus point. For more details on using the Search Collection window features click the Help button.
Note that the Search Collection window will be blank if no streets within the county are found. Also, you need to close the Search Collection window before returning to LandView to look for another street.
If you need to identify the state, county, and census tract associated with the map focus point, select Segment Settings from the MARPLOT Objects menu to determine which side of the street contains your address.
Then position the map focus point on that side and select Identify census areas at current map pointer under LandView in the MARPLOT Sharing menu.
