Exploring Leaflet Vector Classes

leaflet

This post, third in my series on the Leaflet API, explores the vector classes. Vector graphics are primitive geometric shapes that easily scale across pixel resolutions, such as points, lines, circles, and polygons. The point class, L.LatLon was covered in my previous post, Exploring Leaflet Geographic Classes. The remaining vector classes are shown below.

As was the case with the geographic classes, there are similar vector classes available in all online map APIs.

Not pictured above are L.MultiPolyline and L.MultiPolygon, as those are contained in L.FeatureGroup, which extends L.LayerGroup, which I will covered later in my series. I included L.PolyUtil and L.LineUtil because they have some helpful functions, such as Douglas-Peuker line simplification, distance and proximity calculations, and clipping.

A picture is worth a 1,000 words, so I’m not going to expand on my diagram. You can read more in the Leaflet API documentation.

Next stop, raster classes.
