Orthophoto can be displayed as a part of the model, either as background images in 2D, or draped to terrain surfaces in 3D.

Find it here:

The Orthophoto Tool

Before images can be displayed, a task defining the data source must be created with the “Orthophoto Tool” from the “Insert” menu.


Templates: There are no default templates for Orthophotos, but it is possible to distribute such templates as part of a company configuration. User-defined templates will also appear in this list - see separate section.

Orthophoto Source Paths

Orthophoto source files should be placed locally on each computer for optimal speed. The path container can hold several paths to support different locations by different users. We advise users to agree upon one path to put orthophotos. The path will be preceded by a green checkmark to indicate if there is a valid path on the current computer. If there are several valid paths in the task, only the first path will be checked and the orthophotos must be put here, if not they will not be found.


Refresh - Removes the existing cache and starts generating new tiles.


Select features - If the orthophotos are to be draped on a surface for 3D viewing, select the features with this function. Draping will only work with surface features.


Preview 2D/3D - The result can be previewed in 2D/3D with this function. The preview button will not be enabled before the tool has the minimum necessary input. The 3D button will not be enabled if there is no surface attached.

Finish - This function will store the information to the task tree. The finish button will not be enabled before the tool has the minimum necessary input.

Using Orthophoto with models

The Orthophoto Task will appear in the task tree in the Explorer Window. Select any combination of data in the task tree (by pressing the Control key) together with the Orthophoto Task. Then right-click and select “View in 3D” or “View in Plan” to draw data. Orthophoto can also be stored in Plan Presentations or 3D Presentations.

Tile generation

The image tile generator is dynamic, It only generates the requested image tiles depending on your view and zoom level. First-time image generation may take a while, depending on the size and resolution of the source images. Once tiles are generated and loaded into the cache, views will reuse these at a much more sufficient speed.

Shared Worksets

Sharing of source and cached images is not supported by the current version. On shared worksets, only the tasks are shared, so each user must retain a folder with the source orthophoto images present.

Create user-defined templates

By right-clicking the Orthophoto Task and selecting “Save as Template” the setup will appear in the list of templates. They can now be reused to create new Orthophoto tasks in new Quadri models, given that they belong to the same CRS.

Supported formats

A complete list of supported formats can be found at http://www.gdal.org. In addition to these formats, the systems support georeferenced files of type SOSI and MMM.


Transformations are not supported by the current version. The geo-referenced information must be of the same CRS as the Quardi Model.

Cache Management

There is no cache management in the current version.
