Intersect Analysis
Find features that intersect between two datasets.
Overview
Intersect analysis identifies features that spatially overlap between two datasets, creating new features at intersection locations.
Inputs
- Input Dataset: Primary dataset
- Intersect Dataset: Dataset to intersect with
- Output Type: Intersection geometry type
Outputs
New dataset containing:
- Intersecting features
- Attributes from both datasets
- Intersection geometry
Example
{
"input_dataset_id": 123,
"intersect_dataset_id": 124
}
Use Cases
- Overlay analysis
- Spatial filtering
- Feature extraction
- Area calculations
Notes
- Output geometry type depends on input types
- Attributes from both datasets are included
- Empty intersections are excluded
- Processing time depends on dataset sizes
