Wellman (1971) presented erroneous data on lineaments in Papua New Guinea. The main faults and folds in Papua New Guinea are determined by ground and remote sensing surveys by the Bureau of Mineral Resources, the Geological Survey of Papua New Guinea, and oil exploration companies, as shown on a 1:1,000,000 scale geological map. The dataset likely contains corrected fault classifications and locations.
Use Cases
- Correcting historical geological maps based on modern survey data
- Analyzing tectonic fault systems based on ground and remote sensing surveys
- Comparing fault classifications based on airphoto and radar imagery analysis
- Mapping fold systems based on extensive field mapping over 25 years
Strengths
- Based on surveys by multiple authoritative organizations (Bureau of Mineral Resources, Geological Survey of Papua New Guinea, oil companies)
- Incorporates data from airphotos at scales from 1:20,000 to 1:80,000 and side-looking airborne radar imagery
- Derived from extensive field mapping over the last 25 years
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Data may reflect geographic bias inherent to data_gov_au
