Developing Geological Information Systems
Introduction
•Redesigned geological information systems
•Address data management problems
•Outline the development of a solution
Developing Geological Information Systems
The Problem
•Databases designed to store data for maps
•Creates “free text” problem
•Significant duplication of data
•Difficult to use for analytical purposes
Developing Geological Information Systems
Sandstone, slate: moderately to well sorted, variably rounded quartz with minor feldspar and lithic grains in quartz silt or clay matrix; minor quartz granule conglomerate; thin to very thick bedded; black fossiliferous …
Developing Geological Information Systems
Our Solution
1. Geological data model
2. Build data storage and management services
3. Client systems
Developing Geological Information Systems
Conceptual Model
Foundation for our work
Adopted the North American Data Model
•Robust geological approach
•Technology-neutral
GeologicalUnit
Developing Geological Information Systems
Logical Model
Content constrained by
