Creating projects and adding data
In this video a project is created and a digital elevation model (DEM) in Geotiff format is added and visualised. The DEM is downloaded from SRTM dataset which is freely available to download or you can source and upload your own terrain models.
If you upload an orthophoto Geotiff file, it is detected as raster imagery and will be tiled and displayed as 2D image on the map, draped over your terrain model if you have one.
Adding pointcloud data
You can add LiDAR, laser scanner or any other pointcloud data in .las or .laz format. The coordinate system of the uploaded file will be auto-detected if it is available in the file header, or you will need to specify the correct coordinate system.
Massive pointcloud data can be uploaded and streamed with no restriction in size and resolution. The tools for 3D measuring, feature extraction and project collaboration all apply to pointcloud data.
Adding textured obj mesh models
To add an obj textured mesh model, you need to create a zip file containing .obj, .mtl and the texture image files of the model to upload to your project. You also need to specify the coordinate system (EPSG code) of the model and any shift in XYZ. For example if the model is produced by Pix4D photogrammetry software, you can find the _offset.xyz file under params folder which contains the model offset in XYZ.
You can also export the model as Cesium 3D Tiles format if is available in your processing software, such as Bentley ContextCapture, and upload the zipped file.
Adding 3D CAD and BIM models
3D solid models or polygons are supported in DXF, DGN, DWG, DAE or IFC formats. You’ll need to specify the coordinate system (EPSG code) of your drawing to be visualized in the correct geographic location on the map.
The model will be overlaid with other data in your project and can be used for volume calculations and estimating the difference between the actual terrain and the design model.
Import vector shape files
Any area or polygon features can be imported as 3D vector tiles. The shape file should be converted to a zip format before uploading. Vector tiling is best suited to shape files that have 3D coordinates. With 2D vector objects you can select the shape-to-raster transform option to project the shape file as raster image over the terrain. This option is available in ‘Data Management’.
With 4DMapper, you can process photos to 3D models with full options for importing external image coordinates (e.g. from a PPK or RTK), importing and marking GCPs and selecting coordinate systems. Generate pointclouds, terrain andorthophotos with full survey grade reports.
You can measure points, lines, areas and volumes and extract the 3D features to your computer. Assign metadata or link to an external database. Measure volumes on any 3D model, terrain model or pointcloud with various calculation options. .
Click on a 3D model and 4Dmapper will find the best photos of that point with a target on each. You can the place a tag, add notes, custom attributes or connect to a file or database to bring external data onto the model.
You can use the 4DMapper REST APIs to automate workflows, upload, download, processing tasks, user management and more. Build your own application (desktop/web or mobile). Full API documentation with examples is available in our API Documentation page.
