Creating projects and adding data

In this video a project is created and a digital elevation model (DEM) in Geotiff format is added and visulized. The DEM is downloaded from SRTM dataset which is freely avilable to download or you can source and upload your own terrain models.

If the uploaded Geotiff file is detected as raster imagery, e.g. orthomosiac image, it will be tiled and displayed as 2D image on the map.


Adding pointcloud data

You can add LiDAR and scanner data or any pointcloud in .las or .laz format. The coordinate system of the uploaded file will be auto-detected if it is available in the file header otherwise you need to specify the correct coordinate system.

Massive pointcloud data can be uploaded and streamed with no restriction in size and resolution with advanced tools for 3D measuring, feature extraction and project collaboration.


Adding textured obj mesh model

To add an obj textured mesh model, you need to create a zip file containing .obj, .mtl and texture image files of the model before uploading to your account. 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 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, e.g. Bentley ContextCapture, and upload the zipped file.


Adding 3D CAD and BIM models

Any 3D solid model or polygons are supported to be imported as DXF, DGN, DWG, DAE or IFC format. You’d need to specify the coordinate system (EPSG code) of your drawing to be visualized in a correct geographic location on the map.

The model will be overlaid with other data source in your project and can be used for volume calculations and estimating differences between the project design model and actual terrain condition.


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 if your shape file has 3D coordinates, otherwise you can select shape-to-raster transform option to project the shape file as raster imagery over the terrain. This option is available from ‘Data Management’.


Photogrammetry processing

With 4DMapper, you can process photos to 3D models with full options for importing external image coordinates (e.g. from a PPK or RTK corrections), importing and marking GCPs, selecting coordinate systems and generating full survey grade report.


3D Measurments

You can create 3D features, edit, extract and download to your local computer, assign metadata or external database, measure volumes using any 3d model, such as pointclouds or terrain data with various calculation options.



If you click on a 3d model, 4DMapper will serach and find the exact position on nearby photos and show you the pixel location on each photo. Then you can place tags, add notes and custom attributes or use external csv or database for adding attributes to each pin.



There are two methods for sharing maps and projects. The first method is to create an external shared view of the current project, recipients do not have to login and will see what you setup for them to see.

The second option is adding internal project collaborators and users and assigning specific projects and roles to them, so they can interact and collaborate with other internal users.
