Relationship Class
USGS MDM Status/Lessons Learned
• Just do it
• Data management of ground validation points
• Useful for topological update (feature class)
• Annotation classes
• Simplify USGS Open File Report process.
Future Research
• How can the relationship class help us with spatial relationships?
• How do we extract the high-res data from rasters?
• Interpolation of seismic profile data in Geostatistical Analyst
• How do we manage geologic interpretations in MDM?
•Talk to the Geology Data Model Crew
• Publish USGS Open File Report Spring 2005
