The document describes a new Cadastral Extension being developed for ESRI's Survey Analyst software. The extension will allow users to build and maintain an accurate cadastral fabric by incorporating geodetic control, survey measurements, and weighted least squares adjustments. This will incrementally improve the positional accuracy of cadastral boundaries and associated GIS layers over time. The key components include a dimensioned cadastral fabric, geodetic control coordinates, a weighted least squares adjustment process, and accumulated displacement vectors to adjust other feature layers.
34. Example of Feature Adjustment Utility line features incorrectly located with respect to the fabric… Using LSA vector field, utility line features are adjusted to the fabric.
38. GIS in support of CORS? Mission: The mission of Stark GIS is to develop the most accurate mapping system possible , enabling all current and future mapping to be referenced to a common framework . Stark GIS also is charged with disseminating the data created and encouraging Stark County's townships, cities, and villages to develop and utilize their own GIS.

Accurate fabric aids height modernization goals Pennsylvania Height Modernization Forum Report July 16, 2004 Sponsored by the National Geodetic Survey and the Pennsylvania Department of Transportation Co-sponsored by the United States Geological Survey and Herbert, Rowland & Grubic, Inc. A positionally accurate cadastral fabric can truly modernize FEMA FIRM maps by adjusting the flood plain boundary to the fabric, bringing about significant improvements in the insurance assessment process.
