Abstract
Updating GIS Geometry With Survey Data
Track: Surveying
Author(s): Holger Schade
ArcSurvey is a unique innovation to provide survey tools that extend the functionality of ArcInfo. The extended functionality includes:
An interface between survey data formats and the GIS database;
Data storage models and processing methods for survey measurements;
Survey measurement visualisation;
Advanced survey measurement editing and management;
Storage of survey computations within the database; and
The ability to associate the original data (e.g. survey measurements) with features in the GIS.
Additionally ArcSurvey provides significant quality management benefits by linking meas-urements with GIS features. Such functionality enables a detailed report to be created at any time that includes:
The source and quality of all measurements associated with the feature;
The computations performed on the measurements to create the survey point; and
Full statistical information describing the quality of the survey point and hence the quality of the feature vertex associated through the link.
The presentation will highlight the current problems of integrating GIS features and survey data in a GIS system, and it will describe the concepts and methodologies used in ArcSurvey to address these problems.
