Introduction

brdrQ is a QGIS plugin designed to align geometries with reference data. It helps users correct spatial discrepancies adjusting geometries to match reference sources using brdr.

Installation

1. Open QGIS.
2. Go to Plugins → Manage and Install Plugins.
3. Search for brdrQ.
4. Click Install Plugin.
5. Once installed, the plugin will appear in the plugin toolbar.

This plugin provides tools to align geometries to reference data.

QGIS compatibility

brdrQ is currently maintained to run on both:

• QGIS 3 (Qt5 / qgis.PyQt)
• QGIS 4 (Qt6 / qgis.PyQt)

Compatibility wrappers are used in the plugin code for API differences (for example Qt enums and map-layer filter enums).

here you can find links to the different tools that are currently provided:

• Feature aligner - Feature-by-feature alignment with predictions
• Autocorrectborders (BULK) - Bulk alignment of your data to a reference layer
• GRB Updater (BULK) - Bulk alignment to latest GRB (Flanders - Belgium) based on predictions and provenance

Possible workflow

The tools can be used separately or in combination with each other:

1. Use Autocorrectborders (BULK) to align your thematic data to a reference layer. A CORRECTION_ layer is returned that indicates the brdrq_state of the alignment.
2. Use Feature aligner on the CORRECTION_ layer to review/update features that are not automatically updated, according the ‘brdrq_state’ (to_review, to_update).
