WebbGet a geometry that represents all points within a distance of this geometry. A positive distance produces a dilation, a negative distance an erosion. A very small or zero distance may sometimes be used to “tidy” a polygon. Parameters: distancefloat The distance to buffer around the object. resolutionint, optional WebbA point is a zero-dimensional feature and has zero length and zero area. Parameters: argsfloat, or sequence of floats. The coordinates can either be passed as a single parameter, or as individual float values using multiple parameters: 1 parameter: a …
