3D model – Dominica, Pichelin, February 2024
Description
|
Science Case Name |
Multi-hazards in the Caribbean SIDS |
|
Dataset Title |
3D model – Dominica, Pichelin, February 2024 |
|
Dataset Description |
3D model generated using images captured using a DJI drone in Pichelin. |
|
Key Methodologies |
The 3D model for Pichelin 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). |

Pichelin region in Dominica |
|
Key Indicators |
Point cloud, 3D mesh, DSM and DTM |
|
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 Pichelin was generated from the nadir drone images using photogrammetric techniques employed by the software Pix4D. |

Accessibility |
|
|
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 |
