Summary
Adds a fallback mechanism in
get_geo()to use dataset-levelgeometryextentmetadata when event-level geographic information is unavailable.Changes
Preserve existing event-based geographic extraction logic
Add fallback to
PanDataSet.geometryextentGenerate geographic bounds from:
westBoundLongitudeeastBoundLongitudesouthBoundLatitudenorthBoundLatitudeSkip empty event geometries safely
Motivation
Some PANGAEA datasets do not populate
eventswith geographic coordinates but still provide valid spatial coverage throughgeometryextent. This update improves robustness and geographic metadata coverage across datasets.
