lawn_simplify | R Documentation |
Takes a data-LineString or data-Polygon and returns a simplified version.
lawn_simplify( feature, tolerance = 0.01, high_quality = FALSE, mutate = FALSE, lint = FALSE )
feature |
A data-Feature<(data-LineString, data-Polygon, data-MultiLineString, data-MultiPolygon)>, or data-FeatureCollection, or data-GeometryCollection |
tolerance |
(numeric) Simplification tolerance. Default value is 0.01. |
high_quality |
(boolean) Whether or not to spend more time to create a
higher-quality simplification with a different algorithm. Default: |
mutate |
(boolean) allows GeoJSON input to be mutated (significant
performance increase if |
lint |
(logical) Lint or not. Uses geojsonhint. Takes up increasing
time as the object to get linted increases in size, so probably use by
default for small objects, but not for large if you know they are good
geojson objects. Default: |
Internally uses simplify-js (https://mourner.github.io/simplify-js/) to perform simplification.
A simplified feature.
A Feature of either data-Polygon or data-LineString.
