Latest Patents

Okuda’s listed patents address interactive database retrieval and the maintenance of geographic information links.

“Methods for Retrieving Database with Image Information” describes a two-stage process for finding text-based attributes through corresponding image information, such as a map. The quantitative stage supports rough or partial-overlay searches and stores results in a work file. The qualitative stage applies retrieval conditions through a function sheet overlaid on the original image, then displays the results.

“Link Information Maintenance and Management Method” aims to reduce the work required to maintain links between geographic information and attribute data. The method compares geographic information using corresponding points identified by an operator, evaluates update dates for link and attribute information, and generates current links. Those links are then used to display attribute information and associated closed areas on updated geographic information.
