Editing spatial data

Editing spatial data, i.e.:

  1. changing the Attributes of existing Objects,
  2. changing the Geometry of existing Objects
  3. adding new Objects,
  4. deleting Objects,

is one of the primary use cases of the System. Whether your database contains development sites, water mains, lighting data or the results of a wildlife survey, editing your data looks the same. The following article provides general notes on data editing and references to specific articles.

In the System, Geometry (commonly referred to as graphical data) and Attributes (commonly referred to as descriptive data) are edited simultaneously and stored in a single database.

Before you begin

  1. Only users who have been granted the appropriate rights by the administrator can edit the data.
  2. Editing can be done in the part of the System accessible via a browser and via a plug-in to QGIS. We suggest that simple edits are made via the browser, while large, advanced edits are made in QGIS. Why? Because it is a desktop programme, with many tools to enhance editing.
  3. The editing tools vary slightly depending on the Geometry Type.
  4. The following articles refer to General Layers. Layers from Data Models may have different editing procedures. These procedures are described in the documentation of the respective modules.

Use cases:

  1. How do you add a new object to a Vector Layer: Spot?
  2. How do you add a new object to a Vector Layer: Linear?
  3. How do you add a new object to a Vector Layer: Polygon?
  4. How do you delete an object?
  5. How do you change the geometry (shape) of an object?
  6. How do you delete a single vertex?

For more descriptions of the editing tools, see the Editing Tools Panel article
