Understanding Coordinate Management in the Geodatabase
Date Published: 06-07-2007
Summary:
This white paper is for users who want a more comprehensive understanding of how feature coordinates are managed within the geodatabase. It discusses the properties of a spatial reference, feature coordinate storage in the geodatabase, high precision vs. low precision spatial references, and data migration strategies between the two types of spatial references.
Description:
This white paper examines how feature coordinates are managed within the geodatabase. It has three main objectives:
- To provide background information on the spatial reference property of geographic features in ArcGIS.
- To explain how feature coordinates for vector based geographic data are stored and managed within the geodatabase.
- To discuss data migration strategies for users who may be working with GIS data in both high precision (ArcGIS 9.2) and low precision (pre-ArcGIS 9.2) spatial references.
This will enable users to better manage their GIS data, and help them leverage the geodatabase in their vector data migration workflows.
