Shapely point object
WebbThe Shapely manual for LineString states: A sequence of Point instances is not a valid constructor parameter. A LineString is described by points, but is not composed of Point instances. So if I have two points A and B, is there a shorter/better/easier way of creating a line AB than my current "best" guess...

You can broadcast to a MultiPoint () object, which is sequence of Point () objects, in a single step. Next, you may want to create a buffer for the line. A buffer around a line is the polygon representing the area in which all points are within a given distance.
WebbFundamental geometric objects that can be used in Python with Shapely module The most fundamental geometric objects are Points, Lines and Polygons which are the basic ingredients when working with spatial data in vector format. Python has a specific module called Shapely that can be used to create and work with Geometric Objects.
