The organization and management of Canada's national gravity data base

Abstract

The National Gravity Data Base has been developed over the past 15 years in response to national and international geoscience requirements. The data base contains information pertaining to gravity standardization networks in Canada and abroad, gravity anomaly mapping in Canada, instrumental parameters, digital terrain and crustal motion. Flexible data management capability and minimal software maintenance costs result from extensive use of the System 2000 DBMS package. Interfaced with the data base are several applications software systems which perform various reduction, editing, adjustment, updating, retrieval and display operations.
