GISLayer - Filter Processed Data

Changes in vector layers (newly added geometries, modified geometries, deleted geometries) can be queried.

Step 1: Attribute Table 🡪 Operation-> Show Changes>

For this query, go to the 'Show Changes' submenu of the 'Operation' menu in the vector layer attribute table.

Attribute Table -> Operation-> Show Changes

There are 4 options:

1. List Recently Added
2. List Edited
3. List Deleted
4. List Available

2.1. List Recently Added

This option lists new geometries added to the vector layer. The example is shown below.

Here is the first version of a vector layer.

After adding some new geometry to this layer, the 'List Recently Added' option is selected.

Then, only recently added data is listed in the attribute table.

2.2. List Edited

This option lists the changed geometries that already exist in the vector layer. The example is shown below.

After editing some geometries, the 'List Edited' option is selected.

Then, only the edited geometries are listed in the attribute table.

2.3. List Deleted

This option lists deleted geometries that previously existed in the vector layer. The example is shown below.

Initially, all data in the layer and its attribute table appear as follows.

After deleting some geometries, the 'List Deleted' option is selected.

Then, only the deleted geometries are listed in the attribute table.

2.4. List Available

This option lists all existing geometries in the vector layer. The example is shown below.

'List Available' option is selected.

Then, all geometries in the layer are listed.
