Ungeocoding is the process of removing objects that have been attached to data records. There are times when it will be necessary to ungeocode an entire table or selected records in a table. For example, you have geocoded a database of customers using US_ZIPS.TAB. Later, you want to geocode the database again, using street addresses instead of postal code centroids since the geocoding will be more precise. MapInfo Pro allows you to delete all graphic objects associated with this table. You can then geocode your database again, using more specific coordinates. Ungeocoding only selected records from your table is useful when the location information changes for a relatively small number of records, such as address changes in a geocoded list of customers.

To ungeocode and remove one or more of the objects in a table:

  1. Make the table you are working with the editable layer of the active Map window.
  2. Select the object or objects.
  3. Click the Map window to make it active.
  4. On the SPATIAL tab, in the Clipboard group, click Cut.

To ungeocode an entire table:

  1. On the TABLE tab, in the Maintenance group, click Table, and Modify Structure to open the Modify Table Structure dialog box.
  2. Clear the Table Is Mappable check box. Click OK.
    CAUTION:
    This action will remove all graphic objects from your table. This action cannot be undone. If you are unsure of losing your points, save a copy of the table first.
  3. A warning dialog box appears. If you are sure about removing all the objects, click OK.

    All graphic objects have been removed from your table.

Make sure that you do not ungeocode your source tables. Unless you have created a backup of that table, you will no longer be able to display that table as a map or use it for geocoding.
