CRASAR-U-DROIDs: 122,502 Building Views for Damage Assessment

CRASAR-U-DROIDs contains 265 orthomosaic images featuring 122,502 views of 21,716 building polygons for disaster response. Created by CRASAR, the collection focuses on building damage assessment and polygon alignment using small Unmanned Aerial Systems (sUAS).

Use Cases

• Training models for building damage assessment using labeled building polygons
• Developing algorithms for building polygon alignment in orthomosaic imagery
• Evaluating sUAS-based disaster response inspection techniques

Strengths

• Contains 122,502 views of 21,716 building polygons
• Includes 265 orthomosaic images for disaster response
• Linked to multiple peer-reviewed Arxiv publications for methodology

Limitations

• Geographic scope is restricted to the United States
• Metadata does not specify the exact damage scale used for labels
