The convex hull of a geometry is the smallest convex Polygon containing all the points in each geometry, unless the number of points in the geometric object is less than three. crs. geopandas.GeoSeries.convex_hull¶ property GeoSeries.convex_hull¶. Vector data includes points, lines, polygons Raster data includes images, digital elevation models, 2-D fields source: MassGIS by way of ETH Zurich GeoJSON ... Convex Hull. For two points, the convex hull collapses to a LineString; for 1, a Point. Graham scan is an algorithm to compute a convex hull of a given set of points in O(nlogn) time. GeoSeries.convex_hull¶ Returns a GeoSeries of geometries representing the smallest convex Polygon containing all the points in each object unless the number of points in the object is less than three. Then calculate the area of the convex hull, and then calculate the points/area. GeoPandas (and shapely for theindividual objects) provides a whole lot of basic methods to analyse the geospatial datan (distance,length,centroid,boundary,convex_hull,simplify,transform,..). tolist ()) polygon = point_collection.

For two points, the convex hull collapses to a LineString; for 1, a Point. convex_hull. GeoSeries.envelope¶ Further, the shape is convex, meaning that the straight line between any two points will also be contained within the convex hull. Every point is inside of the convex hull, but some points will be on its boundary. Returns a GeoSeries of geometries representing the convex hull of each geometry.
