Users can export 3D models in .obj, point clouds in .LAS, and rasters in GeoTIFF formats. If you need to export project outputs in any other format, we would love to hear from you. Write to us here.
By using RTK/PPK drones along with Ground Control Points (GCP), you can achieve a horizontal accuracy of less than 10 cm and vertical accuracy of less than 15 cm. We are continuously working towards getting down our global accuracy to a range of 5-10 cm.
Currently, Preimage generates rasters with a maximum resolution of 4 cm/px. However, the actual GSD achieved depends on various factors such as the drone flight altitude and the resolution of the input imagery.
Preimage supports eight classes for point cloud classification which include: ground, vegetation, buildings, water, paved area, bridges, vehicles, and structures. Additionally, Preimage also supports a ground versus non-ground segmentation of point clouds which provides further refinements on the aforementioned classes.
To add users to your workspace in Preimage
Navigate to the workspace settings on the left sidebar in the web app.
Select the "Add user" tab.
Enter the email address of the user you want to add to your workspace and select their level of access.
An invitation email will be sent to the user to join the workspace.
You can manage the level of access for each team member using different permission levels like
can view and download the outputs of the projects in the workspace.
can create projects, in addition to viewing and downloading the outputs.
have all the permissions of editors, along with the ability to manage workspace settings and make payments.
have complete control over the workspace and its contents. They can even delete the workspace, and add or remove other owners.
Currently, it is not possible to share a single project with specific users outside of your Preimage workspace. However, you can share your project externally by creating a shareable link. Anyone with access to the link will be able to view the project outputs.
Yes, Preimage viewer supports annotation and measurements on rasters such as DEM, DTM, and orthomosaic. We are also working on adding support for 3D annotations and measurements in the near future.
At present, the Preimage viewer does not offer editing capabilities. To edit your files, you can export them from Preimage and import them into alternative editing tools. We are actively working on incorporating editing functionality within the viewer and would appreciate any suggestions for features you would like be added.
