WhiteStar LeaseBuilder™ is a web-based application that allows users to easily calculate land polygons based on the Public Land Survey System given the parcel's legal description.

Users can specify multiple tracts for the same lease, and WhiteStar LeaseBuilder will calculate and return the combined results with as few distinct polygons as possible, for optimal simplicity. Any mapping application with Internet access and proper entitlement can use the service.

Both WhiteStar LeaseBuilder and WhiteStar WellBuilder work in conjunction with WhiteStar Grid. The software and operating environment behind the WhiteStar LeaseBuilder service are regularly upgraded and enhanced by WhiteStar.

Subscribers don't need to maintain a costly and labor intensive IT infrastructure. Users have access to a programming-language independent software API that ties into Safe Software's popular FME workbench. Third party applications can easily add WhiteStar LeaseBuilder or WhiteStar WellBuilder functionality to new or existing software applications.
