getH3UnidirectionalEdgeBoundary method
Get the vertices of a given edge as an array of lat, lng
points. Note
that for edges that cross the edge of an icosahedron face, this may return
3 coordinates.
Implementation
@override
List<GeoCoord> getH3UnidirectionalEdgeBoundary(BigInt edgeIndex) {
return using((arena) {
final out = arena<c.GeoBoundary>();
_h3c.getH3UnidirectionalEdgeBoundary(edgeIndex.toInt(), out);
final coordinates = <GeoCoord>[];
for (var i = 0; i < out.ref.numVerts; i++) {
coordinates
.add(out.ref.verts[i].toPure().toDegrees(_geoCoordConverter));
}
return coordinates;
});
}
