We recommend Google Chrome as your primary browser for your PC.

The Kunta3D city model also works in the latest versions of the following browsers:

• Edge
• Firefox
• Safari

On mobile devices, we support the Android operating system.

You log in to the city model via the icon in the top right corner. There are four login options:

• Login with Google account
• Login with Facebook account
• Login with email address and password
• Login with disposable link

The first time you log in, you will need to create a user account for yourself. This is done only once and in the future the city model will be logged in directly with the created user ID.

Note! If you already have an account in the city model, please use the same email address to log in.

You can set up your own project via the editor interface. You will need to log in to the city model first to be able to set up a project.

1. On the left side of the view, select 'Project' from the project menu.
2. Go to the 'Project info' tab.
3. Choose the right organisation for your project.
4. Enter a name for the project and select 'Save Project'.
5. The project will appear under the 'Projects' tab.

You can save your project via the 'Projects' menu:

1. Go to the 'Project info' tab and select the 'Saving' tab.
2. Select 'Save Project'.

Note! All editing done to the project must always be saved separately. If you accidentally close the browser without saving the project, the project will open with the latest saved settings.

If something irreversible happens while editing a project (for example, you move the model to the wrong location and you can no longer place it in the right location), you can refresh your browser and reopen the project. The project opens with the last saved settings.

3D models of buildings can be uploaded to the city model in three different formats. The file format is selected according to the intended use of the model.

• IFC (Industry Foundation Classes) -  a general standardized format that contains information about the geometry and properties of the model, such as material information or coordinates.
• glTF (GL Transmission Format) -  suitable for presenting 3D geometries such as buildings, vegetation and other objects. Includes 3D shapes and views. Faster and compressible than OBJ. We recommend this format primarily if both glTF and OBJ are available.
• OBJ (Object) - suitable for presenting 3D geometries such as buildings, vegetation and other objects. In addition to geometry, models can include colors or textures.

LandXML format is recommended for uploading terrain models. LandXML is also suitable for presenting routing (bike routes, etc.). If necessary, the terrain model can also be imported in OBJ format.

Layout drawing data can be uploaded either as an image file (JPG, PDF), which is positioned using the plot's corner points, or in the GeoTiFF or GeoJSON format, which already contains coordinate data.

Point cloud data can be uploaded in two different formats:

• LAS - Includes point cloud data, coordinates, classes, and color values.
• LAZ - Compressed LAS file.

If you have classified your point cloud data with TerraScan, you can include the point cloud classes in PTC format when uploading the point cloud.

Each project created has a project-specific id and a project link. A project-specific link can be found on the 'Saving' tab in the project information under 'link'.

The link can be  shared by copying it for example to an e-mail.

Note! The person must have access rights to the project when sharing the link. If the rights have not been set in advance, the project will not open using the link.
