Pic. 2.5. Resource groups.

The content of resource group is displayed after a click on resource name in a child resources pane of main resource group (see item 4 in Pic. 2.2.). On resource group page there is a pane with a list of resources in root group and user permissions pane. Layer properties are displayed after a click on a name of a layer in child resources pane. E.g. user can click on a resource of type vector layer.

After a click on layer in child resources pane user is taken to a vector layer properties and attributes page (see Pic. 2.6.).

2.4.4. Feature table

To view feature table after login navigate to a child resource group (see item 4 in Pic. 2.2.), where would be displayed resource types. Then select from child resources a resource with type vector layer and press the “Table” icon opposite the resource or select an action for a vector layer called “Feature table” in actions pane (see Pic. 2.7.).

Feature table allows to perform the following operations with a selected record (see Pic. 2.8.):

  1. Open

  2. Edit

  3. Delete

  4. Use Search Box

A table will be displayed in a new tab. Table allows to perform the following operations with a selected record Pic. 2.11.:

  1. Open

  2. Edit

  3. Delete

  4. Go to (after a click the selected feature will be displayed on the map)

2.4.5. Update resource

To edit a resource after login navigate to a child resource group (see item 4 in Pic. 2.2.), where would be displayed resource types. Then select from child resources a resource with type vector layer and press the “Pencil” icon opposite the resource or select the layer and then select an action called “Update” in actions pane (see Pic. 2.12.).

On the first tab “Resource” you can edit the next fields:

  1. Display name (you can change the resource’s name)

  2. Keyname

  3. Parent (you can change the resource group through moving the resource)

  4. Type

  • Tick in “FT” column means that the attribute is displayed in the identification window.

  • Tick in “LA” column means that the attribute gives its name during the identification and forming of the tabs list.

For each field name you can set the corresponding pseudonym to use it for display in the identification window instead of the name.
