3D model – Dominica, Coulibistrie, February 2024

Science Case Name

 Multi-hazards in the Caribbean SIDS

Dataset Title

3D model – Dominica, Coulibistrie, February 2024

Dataset Description

3D model generated using images captured using a DJI drone in Coulibistrie.

Key Methodologies

The 3D model for Coulibistrie was generated from the nadir drone images using photogrammetric techniques employed by the software Pix4D. The image Coordinate System is WGS 84 (EGM 96 Geoid0), but the Output Coordinate System of the 3D model is WGS 84 / UTM zone 20N (EGM 96 Geoid).

Temporal Domain

February 2024

Spatial Domain

Coulibistrie region in Dominica

Key Indicators

Point cloud and 3D mesh

Data Format

3D mesh: FBX, DXF, OBJ and PLY

Point cloud: LAS, LAZ, PLY and XYZ. Each point cloud data set is merged into one file.

Source Data

Drone images were captured using a DJI drone. The 3D model for Coulibistrie was generated from the nadir drone images using photogrammetric techniques employed by the software Pix4D.

Accessibility

Zenodo, 10.5281/zenodo.15224567

Stakeholder Relevance

The generated products from drone images can be used for mapping and risk management. For example, the generated 3D models can be used to create the digital twin framework.

Limitations/Assumptions

The 3D model was generated without the use of Ground Control Points (GCPs), relying on the positional data from geotagged images. As a result, the model may contain positional inaccuracies
