A new dataset in DataHub can be created using pre-processed files such as point clouds, terrain models, and orthophotos generated in other software. These files can be uploaded to DataHub for visualization and measurement calculations.
Supported File Types:
- Point Cloud: .las, .laz, .txt, .xyz
- Digital Surface Model (DSM): .tif
- Digital Terrain Model (DTM): .tif
- Orthophoto: .tif
Notes:
- Point clouds must include RGB values. Uploads missing RGB information may fail.
- All uploaded files are tiled automatically for use in DataHub. If a DSM or DTM is not included, it will be generated automatically from the point cloud.
- Orthophotos cannot be generated from point clouds. DataHub only uses satellite imagery as texture, overlaid on top of elevation data.
The combination of uploaded files determines the resulting dataset that will be available in DataHub. Here are the possible upload combinations:
Instructions:
1. Open the Datasets Modal. Click the Additional Options button on the right of the date card for your site.
2. Click Create a New Dataset from Pre-Processed Files.
3. Use the Browse button or drag and drop your files into the modal.
Notes:
For .txt or .xyz point clouds, remove any header and include only the point values.
Column order must be:
X, Y, Z, R, G, B
Each one stands for:
X= Easting or Longitude for WGS84
Y=Northing or Latitude for WGS84
Z=Elevation
R =Red value integer between 0-255
G=Green value integer between 0-255
B=Blue value integer between 0-255
4. Choose the coordinate system of the uploaded files (not necessarily the site’s system). Supported options: UTM, WGS84, or the local coordinate system.
*** Important: All uploaded files must use the same coordinate system.
5. Enter the dataset’s date and time. This helps identify and navigate your dataset later.
6. Point clouds from Laser Scans are also supported in DataHub. When uploading laser scans, select Yes and, if the point cloud uploaded is not a laser scan, select No.
7. Click Start Upload. The modal will return to the datasets list and display upload progress.
8. Once the upload completes, DataHub will display the processing status.
9. After processing finishes, the dataset can be loaded for viewing and analysis.
