Layer Mapping tab

If the external data source contains graphical information, we can specify how the information stored on specific layers will be handled.

Items stored on a particular source layer can be transferred to one of the Global Layers in HDC and will then adhere to the same rules concerning accessibility and style.

Layer Mapping tab

TDXM has the capability to combine layers from imported packages (source layers) with layers in HDC database (destination layers).

It is possible to merge source layers with global and/or private destination layers. This configuration can be done on the Layer Mapping tab.

There are two panels on this tab:

Global Layers panel
Private Layers panel

They allow the user to define global and private layer mapping respectively.

Global Layers panel

On this panel, one can add or delete global layer mapping definition (see Layers).

Add global layer mapping definition

To add global layer mapping definition:

Press Add button. Global Layer Mapping dialog box will appear on the screen.
Type the name of the source layer to be imported by TDXM in the Source Layer text box.
Select an existing global layer from the Target Global Layer dropdown menu.
Check or leave unchecked the Apply Style option.
Accept your selection.

Apply Style

Individual entities' (spots, spot groups, etc.) styles on the source global layer will be overwritten with the target global layer style.

Before starting, it is necessary to define global layers in the Administration window: Administration/Drawings/Global Layers.

Deleting Global Layer Mapping Definition

To delete a global layer mapping definition, follow these steps:

Select the global layer mapping definition from the list.
Click on the Delete button.

Private Layers Panel

This panel allows users to add or delete private layer mapping definitions (see Layers) and grant permissions for different users to view and edit private layers.

If the system receives a layer that is not mapped by the Global Layers mapping, it is added as a private layer even if there is no mapping for it.

Adding a Private Layer Mapping Definition

To add a global layer mapping definition:

Click the Add button. The Private Layer Mapping dialog box will appear on the screen.
Type the name of the source layer to be imported by TDXM in the Source Layer text box.
Type the name of the destination layer in the Target Local Layer text box.
Select the owner of the new private layer using the Owner user picker.
Accept your selection.

After adding local (private) layer mapping use Grant permissions button to set who can see and edit data on this layer.

Deleting a Private Layer Mapping Definition

To delete a private layer mapping definition:

Select the private layer mapping definition from the list.
Click on the Delete button.

Granting Permissions to Private Layer

To grant permissions to a target private layer:

Select the private layer mapping definition from the list.
Click on the Grant permissions button. A dialog box titled "Grant permissions for layer" will appear.
Define permission for viewing and editing, then click accept.
