Appendix 9: Geocoding dBase (*.dbf) files

GeoPinpoint Suite supports the following versions of dBase:

 dBase III

 dBase IV



dBase V

Note: For optimal geocoding performance, add an index to the dBase database. Consult the Help

Files of the application used to create the dbf file to find steps on how to add an index. If the

file is being created from Microsoft Access, an index will be added automatically.

Output Columns

For dBase geocoding, add the necessary 4 output columns in the application used to create the dBase file before using. See below for the data types.

If the user attempts to geocode a table without these output columns (x, y, rcode, prescode), they will see the following message even if they have similar column names (e.g.: longitude, latitude, rcode, prescode): “GeoPinpoint requires columns x, y, rcode, prescode or similar columns, but failed to add them into the database. Please add these columns or ensure their existence. Please refer to the user manual for data types of columns."
