Create Strip Map Pages
Feature Description
Strip map page creation generates a series of continuous minimum bounding rectangle faces with specified dimensions along given linear features. These rectangles can be defined as strip map pages for linear engineering projects (road networks, power grids, oil pipelines, river lines).
Note: The orientation of the generated strip pages aligns with the node sequence of the original vector line data.
Parameter Description
| Parameter | Default | Description | Type |
|---|---|---|---|
| Source Dataset | Source vector line dataset for calculation | DatasetVector | |
| Barrier Dataset (Optional) | Barrier dataset containing segmentation points (e.g. administrative boundaries). Generated rectangles will be truncated at barriers and restart calculation. Supports point/line/polygon types with consistent coordinate system as source dataset. | DatasetVector | |
| Target Datasource | Datasource storing result dataset | Datasource | |
| Result Dataset Name | Name for output polygon dataset | String | |
| Page Length | 0.0 | Length along the line (must be ≥0). Unit matches source dataset: meters for projected CRS, degrees for geographic CRS. When 0: auto-assigns 1500m (projected) /0.015° (geographic). | double |
| Page Width | 0.0 | Width perpendicular to the line (must be ≥0). Unit matches source dataset. When 0: auto-assigns 1000m (projected)/0.01° (geographic). | double |
| Start Offset | 0.0 | Distance between first page and line start point (default 0). Unit matches dataset. | double |
| Overlap Distance | 0.0 | Overlapping distance between adjacent pages (default 0). Unit matches dataset. Note: Must be less than half of page length. | double |
Output
| Parameter | Description | Type |
|---|---|---|
| Result Dataset | Output polygon dataset | DatasetVector |
