Geometry Simplification
specdraftimplcandidateSimplification of geometries with Douglas Peucker.
Scope
Conformance Classes
Geometry Simplification is based on the draft of OGC API Features Part 7: Geometry Simplification.
Query Parameters
| Name | Resources | Description |
|---|---|---|
zoom-level | Features, Feature | All geometries are simplified for the zoom level from the widely used tiling scheme in web mapping (WebMercatorQuad). The map scale of zoom level 0 is roughly 1:560 million. The scale doubles for every zoom level (e.g. zoom level 12 is 1:136495). |
maxAllowableOffset | Features, Feature | Deprecated (replaced by zoom-level). All geometries are simplified using the Douglas Peucker algorithm. The value defines the maximum distance between original and simplified geometry (Hausdorff distance). The value has to use the unit of the given coordinate reference system (CRS84 or the value of parameter crs). |
