experimentalLocalIjToH3 method
Produces an H3 index for IJ coordinates anchored by an origin.
- The coordinate space used by this function may have deleted regions or warping due to pentagonal distortion.
- Coordinates are only comparable if they come from the same origin index.
- Failure may occur if the index is too far away from the origin or if the index is on the other side of a pentagon.
- This function is experimental, and its output is not guaranteed to be compatible across different versions of H3.
Implementation
@override
BigInt experimentalLocalIjToH3(BigInt origin, CoordIJ coordinates) {
return using((arena) {
final out = arena<Uint64>();
final resultCode = _h3c.experimentalLocalIjToH3(
origin.toInt(),
coordinates.toNative(arena),
out,
);
if (resultCode != 0) {
throw H3Exception(
'Index not defined for this origin and IJ coordinates pair. '
'IJ coordinates may be too far from origin, or '
'a pentagon distortion was encountered.',
);
}
return out.value.toBigInt();
});
