![Fault Topology](../static/fault_topology_hamersley.png)

## Processing Tools

The plugin provides several QGIS Processing algorithms for working with geological data. These can be accessed through the QGIS Processing Toolbox.

### Paint Stratigraphic Order

The **Paint Stratigraphic Order** algorithm allows you to visualize the stratigraphic order on geology polygons. This tool is useful for:
- Visually debugging the stratigraphic column
- Quality checking unit order
- Creating visualizations of stratigraphic relationships

The algorithm takes:
- **Input Polygons**: A polygon layer containing geological units (e.g., your geology map)
- **Unit Name Field**: The field in your polygon layer that contains unit names
- **Stratigraphic Column**: A table or layer with the stratigraphic column (ordered from youngest to oldest)
- **Paint Mode**: Choose between:
- **Stratigraphic Order** (0 = youngest, N = oldest): Paints a numeric order onto each polygon
- **Cumulative Thickness**: Paints the cumulative thickness from the bottom (oldest) unit

The algorithm adds a new field to your polygon layer:
- `strat_order`: The stratigraphic order (when using Stratigraphic Order mode)
- `cum_thickness`: The cumulative thickness in the stratigraphic column (when using Cumulative Thickness mode)

Units that don't match the stratigraphic column will have null values, helping you identify data quality issues.

## Model parameters
Once the layers have been selected, stratigraphic column defined and the fault topology relationships set, the LoopStructural model can be initialised.

- Quality checking unit order
- Creating visualizations of stratigraphic relationships

The algorithm takes:
- **Input Polygons**: A polygon layer containing geological units (e.g., your geology map)
- **Unit Name Field**: The field in your polygon layer that contains unit names
- **Stratigraphic Column**: A table or layer with the stratigraphic column (ordered from youngest to oldest)
- **Paint Mode**: Choose between:
 - **Stratigraphic Order** (0 = youngest, N = oldest): Paints a numeric order onto each polygon
 - **Cumulative Thickness**: Paints the cumulative thickness from the bottom (oldest) unit

The algorithm adds a new field to your polygon layer:
- `strat_order`: The stratigraphic order (when using Stratigraphic Order mode)
- `cum_thickness`: The cumulative thickness in the stratigraphic column (when using Cumulative Thickness mode)

Units that don't match the stratigraphic column will have null values, helping you identify data quality issues.

## Model parameters
Once the layers have been selected, stratigraphic column defined and the fault topology relationships set, the LoopStructural model can be initialised.

## Processing Tools

The plugin provides several QGIS Processing algorithms for working with geological data. These can be accessed through the QGIS Processing Toolbox.

### Paint Stratigraphic Order

The **Paint Stratigraphic Order** algorithm allows you to visualize the stratigraphic order on geology polygons. This tool is useful for:
- Visually debugging the stratigraphic column
- Quality checking unit order
- Creating visualizations of stratigraphic relationships

The algorithm takes:
- **Input Polygons**: A polygon layer containing geological units (e.g., your geology map)
- **Unit Name Field**: The field in your polygon layer that contains unit names
- **Stratigraphic Column**: A table or layer with the stratigraphic column (ordered from youngest to oldest)
- **Paint Mode**: Choose between:
 - **Stratigraphic Order** (0 = youngest, N = oldest): Paints a numeric order onto each polygon
 - **Cumulative Thickness**: Paints the cumulative thickness from the bottom (oldest) unit

The algorithm adds a new field to your polygon layer:
- `strat_order`: The stratigraphic order (when using Stratigraphic Order mode)
- `cum_thickness`: The cumulative thickness in the stratigraphic column (when using Cumulative Thickness mode)

Units that don't match the stratigraphic column will have null values, helping you identify data quality issues.

## Model parameters
Once the layers have been selected, stratigraphic column defined and the fault topology relationships set, the LoopStructural model can be initialised.

![Fault Topology](../static/fault_topology_hamersley.png)

## Processing Tools

The plugin provides several QGIS Processing algorithms for working with geological data. These can be accessed through the QGIS Processing Toolbox.

### Paint Stratigraphic Order

The **Paint Stratigraphic Order** algorithm allows you to visualize the stratigraphic order on geology polygons. This tool is useful for:
- Visually debugging the stratigraphic column
- Quality checking unit order
- Creating visualizations of stratigraphic relationships

The algorithm takes:
- **Input Polygons**: A polygon layer containing geological units (e.g., your geology map)
- **Unit Name Field**: The field in your polygon layer that contains unit names
- **Stratigraphic Column**: A table or layer with the stratigraphic column (ordered from youngest to oldest)
- **Paint Mode**: Choose between:
 - **Stratigraphic Order** (0 = youngest, N = oldest): Paints a numeric order onto each polygon
 - **Cumulative Thickness**: Paints the cumulative thickness from the bottom (oldest) unit

The algorithm adds a new field to your polygon layer:
- `strat_order`: The stratigraphic order (when using Stratigraphic Order mode)
- `cum_thickness`: The cumulative thickness in the stratigraphic column (when using Cumulative Thickness mode)

Units that don't match the stratigraphic column will have null values, helping you identify data quality issues.

## Model parameters
Once the layers have been selected, stratigraphic column defined and the fault topology relationships set, the LoopStructural model can be initialised.

## Processing Tools

The plugin provides several QGIS Processing algorithms for working with geological data. These can be accessed through the QGIS Processing Toolbox.

### Paint Stratigraphic Order

The **Paint Stratigraphic Order** algorithm allows you to visualize the stratigraphic order on geology polygons. This tool is useful for:
- Visually debugging the stratigraphic column
- Quality checking unit order
- Creating visualizations of stratigraphic relationships

The algorithm takes:
- **Input Polygons**: A polygon layer containing geological units (e.g., your geology map)
- **Unit Name Field**: The field in your polygon layer that contains unit names
- **Stratigraphic Column**: A table or layer with the stratigraphic column (ordered from youngest to oldest)
- **Paint Mode**: Choose between:
 - **Stratigraphic Order** (0 = youngest, N = oldest): Paints a numeric order onto each polygon
 - **Cumulative Thickness**: Paints the cumulative thickness from the bottom (oldest) unit

The algorithm adds a new field to your polygon layer:
- `strat_order`: The stratigraphic order (when using Stratigraphic Order mode)
- `cum_thickness`: The cumulative thickness in the stratigraphic column (when using Cumulative Thickness mode)

Units that don't match the stratigraphic column will have null values, helping you identify data quality issues.

## Model parameters
Once the layers have been selected, stratigraphic column defined and the fault topology relationships set, the LoopStructural model can be initialised.
