Create a new schematisation

New schematisations can be created from the 3Di Models and Simulations panel.

Creating a new schematisation from scratch

To create an entirely new schematisation, go through the following steps:

1. Open the 3Di Models and Simulations panel ().

2. In the Schematisation section, click New ().

3. Choose a schematisation name (obligatory) and tags (optional).

4. If you have rights to more than one organisation, choose the organisation that is to own the new schematisation.

5. In the Spatialite section, choose the option Create new spatialite.

6. Click Next.

7. Fill in other settings, such as the projection and friction type and simulation time step.

8. Click Create Schematisation.

A Schematisation has now been created on the server. The corresponding folder in your local 3Di working directory contains the spatialite and (if chosen) a DEM and/or friction raster. This data itself has not been uploaded yet. See Uploading a schematisation for instructions to upload this data as a new Revision.

Copying an existing schematisation

The New schematisation wizard can also be used to copy existing schematisations. This is useful when for example, you have a schematisation of the “current situation” and you want to investigate one or more alternatives for “future situations”. In such a case, you can copy the current situation situation and start making changes in the copy, without affecting the original schematisation.

Go through the following steps:

1. Make sure you have downloaded the schematisation revision you want to create a copy of.

2. Open the 3Di Models and Simulations panel ().

3. In the Schematisation section, click New ().

4. Choose a schematisation name (obligatory) and tags (optional).

5. If you have rights to more than one organisation, choose the organisation that is to own the new schematisation.

6. In the Spatialite section, choose the option Choose file.

7. Browse to the location where the spatialite is stored that belongs to the schematisation you want to copy. This is usually “<3Di working directory><Schematisation name>work in progressschematisation<schematisation name>.sqlite”

8. Click Create Schematisation.

A Schematisation has now been created on the server. The corresponding folder in your local 3Di working directory contains a copy of the spatialite and all the rasters it references. This data itself has not been uploaded yet. See Uploading a schematisation for instructions to upload this data as a new Revision.
