Managing Cadastre: The GIS Way

Cadastral Editor is an extension to ArcGIS and has largely simplified the complex survey data management process. The primary objective of cadastre data conversion is to develop and maintain basemap layers with high degree of spatial accuracy. Controls such as ground survey points, GPS or RTK points and aerial photography are used to enhance accuracy of cadastre fabrics with time. It stores all legacy records and maps as historical layers including metadata information. Least Square Adjustment (LSA) method is used to adjust the fabrics to enhance spatial accuracy. As new data comes in, the cadastre fabric can adjust and update thus increasing the accuracy with time. Weston has successfully deployed this tool at the City of Encinitas, CA and was awarded the “Special Achievement in GIS Award” by ESRI in 2008 for the implementation. The City is managing their cadastre using these tools now with higher efficiency and effectiveness.
