Abstract
Getting Adjusted: How to Get the Most from Your LINK-Based Adjustment
Track: Database Design, Automation, and Management
Author(s): Bart Guetti
As higher accuracy data becomes more readily available, the accuracy shortcomings of an organization's data holdings sometimes become all too obvious. What was once thought to be "the locational truth" becomes science fiction. By combining new, higher positional accuracy data with existing data, limitations become exposed, placing the validity of the existing data in serious jeopardy.
Many times the existing data has a large amount of capital invested in attribution, which the organization would like to retain without investing an equal amount in upgrading its locational accuracy. This paper will describe GDT's Control Vectors product and its implementation of ArcGIS's ADJUST process for cartographic realignment of transportation related data at a minimal cost. Application of control vector based adjustment to various GDT projects will be presented.
