I am trying to get the area measurements of polygons so I can list them in a table to the side of the map, next to the name of the polygon. This is what I have tried with n
I found that none of the above answers worked for calculating the area of non-contiguous polygons. Here's an example polygon where the above functions returned an area of 0:
For anyone who needs to do that, here is the code that worked for me (using the L.GeometryUtil function from Leaflet.draw):
var poly = // Your polygon layer here; may or may not be contiguous
var area = 0;
for (island of poly.getLatLngs()) {
// If the polygon is non-contiguous, access the island
if (island.length < 2) {
island = island[0]
}
// Sum the area within each "island"
area += L.GeometryUtil.geodesicArea(island);
}
