Advanced Zone Locator

Advanced Zone Locator icon Use the Advanced Zone Locator to extract data that is located in a consistent position across all documents in a class. For example, to extract data from structured documents such as forms.

To set up the locator you configure different kind of zones on a reference document so that during processing the content of each zone is read character by character. This locator is the only locator in Tungsten TotalAgility that performs its own recognition rather than reusing the full-page recognition results.

The Advanced Zone Locator can use a different recognition zone profile for each zone. This provides specific optimizations for hand- and machine-printed characters, alphanumeric characters, and character subsets per zone. In addition, you can apply image preprocessing profiles for each zone to remove static background or noise, leaving clean image snippet.

Reading forms with zones requires that the zones are positioned at precisely the correct location. This is called zone registration. Tungsten TotalAgility provides automatic registration that works well for documents with a significant background structure. Automatic registration requires little effort for set up and testing, and the best practice is that you use it whenever possible. For documents printed and scanned with drop-out colors or with an improper background structure, you can define manual anchors to register zones. Doing so requires more set up and testing but provides more control over how zones are registered.

Although you can click tabs in any order, configure the necessary settings on the General tab before proceeding to the other tabs.

A project created in a previous version of the Transformation Designer that uses the outdated Zone Locator, is automatically updated to use the Advanced Zone Locator as soon as it is opened.

It is not possible to provide a default value for a zone in an Advanced Zone Locator. This means that if no value is found for a zone during testing or extraction, the corresponding field value is empty.

The extraction type of an Advanced Zone Locator is "group" which means this locator has multiple subfields. It is necessary to configure this locator by creating one or more zones and each zone corresponds to a subfield. Use the individual links to create a simple field that is mapped to that subfield or use the Create and Assign Fields button to create all fields at once.

The confidence levels on the Field Settings for a field populated by an Advanced Zone Locator subfield are ignored, and that field is populated with a value from the Advanced Zone Locator regardless of the specified thresholds.
