You can create, modify, or delete features in vector layers.

You must have specific permissions for each type of editing operation in order for the corresponding functions to be enabled.

Create a Feature

To create a new feature:

1. Click the Create a new feature button in the map interface. The Select the feature type to create panel opens, and the corresponding icon appears in the sidebar. This panel lists all layers for which you have permission to create a feature.

   
2. Click the desired layer to select it, then click Next to open the Create Geometry panel.

3. Create the feature geometry according to its type. You can enable the Snap tool and select the layer to which newly created features will snap.

   Point	1. Click the desired location to place the point. 2. To reposition it, click and drag it to a new location.
   Line	1. Click to place the first point. 2. Click additional locations to add vertices. 3. Double-click to complete the line. 4. To modify it, click a vertex (it becomes highlighted) and drag it. Additional vertices appear between existing ones for finer adjustments.
   Polygon	1. Click to place the first vertex. 2. Click to add additional vertices. 3. Double-click to complete the polygon. 4. To modify it, click a vertex and drag it. Additional vertices appear for more precise adjustments.

4. Click Next to open the feature attribute form and, if permitted, attach documents. See the Form section for details.

   
5. Click Create to finalize the feature. The feature appears on the map, and the Select the feature type to create panel closes automatically.

Form

The data entry and editing form for a layer may include several components:

• Layer Attributes (1) – Fields used to describe the feature

• Subform (2) – Table containing records associated with the feature

• Attachments (3) – Section used to associate documents with the feature

Layer Attributes

Attributes may be:

• Required (*) – The form cannot be saved without a value.

• Read-only – These attributes cannot be modified.

Accepted value types include:

• Alphanumeric (text or number)

• Date

• Boolean (true/false)

Input methods may vary:

• Text or numeric fields

• Single- or multi-select dropdown lists

• Checkboxes or toggle switches

Subform

A layer may have non-spatial tabular data associated with its features.

For example, a point layer representing air quality monitoring stations may be associated with a table containing pollutant concentration records measured on different dates.

The subform allows you to add, modify, or delete records in the associated table. When creating a feature, you can complete the subform immediately or later when editing the feature. If you have the required permissions, the subform icons are enabled.

Add a record

1. Click the Add icon to open the table form.

2. Enter the values in the form fields.

3. Click Create. The record appears in the table once the feature is created.

Edit a record

1. Click the Edit icon to open the table form.

2. Modify the desired field values.

3. Click Update. The new values appear in the subform.

Delete records

1. Select the records to delete.

2. Click the Delete icon. A confirmation message appears.

Attachments

If the form includes an attachment section and you have the required permissions, you can attach documents (images, PDF, Word, Excel files, etc.) or URLs.

The maximum file size is 20 MB.

Add an Attachment

1. Click the Add icon to open the file upload or URL entry window.

2. Enter the Subject and Description. Attachments are grouped by subject.

Modify a Feature

You can modify a feature in an editable layer if you have the necessary permissions.

   • Edit Geometry

   • Edit Information

   • Delete

3. Select the desired type of modification.

Edit Geometry

1. Click Edit Geometry, then click the feature to select it. The vertices of lines and polygons appear.

2. To move the feature, drag and drop it to the desired location.

3. To modify its shape, click a vertex and drag it. Additional vertices appear between existing ones for finer adjustments.

   
4. Click Save to apply the changes.
