h3填充返回空列表

Question

我有两个不同的多边形

poly1 = {'type': 'Polygon',
 'coordinates': [[[37.813318999983238, -122.4089866999972145],
 [ 37.7866302000007224, -122.3805436999997056 ],
 [37.7198061999978478, -122.3544736999993603],
 [ 37.7076131999975672, -122.5123436999983966 ],
 [37.7835871999971715, -122.5247187000021967],
 [37.8151571999998453, -122.4798767000009008]]] }

poly2 = {'type': 'Polygon', 
 'coordinates': [[[394848.932324579, 5815933.130831123], 
 [394848.932324579, 5818765.877144514], 
 [389427.971197729, 5818765.877144514], 
 [389427.971197729, 5815933.130831123], 
 [394848.932324579, 5815933.130831123]]] }

当我跑的时候

hexagons = list(h3.polyfill(poly1, 10))

我得到了

[‘88283095d1fff’，‘8828309427fff’，‘88283082cbbfff’，‘8828308251fff’，‘88283082abfff’，‘8828283082ddfff’，‘88282830820bfffff’，‘8828309585fff’，‘8828283082b1fff’，‘882830821dfff’，‘8828309425fff’，‘882828309519fff’，‘882828309519fff’，‘8828308747fff’，‘8828283095aff1fff’，‘88283082b1fff’，‘882830821dfff’，‘882828309519fff’，‘882828309519fff’，‘8828308747fff’，‘882828309585fff’，‘882830821dfff’，‘8828309425fff’，‘882828309519fff’，‘8828308747fff’，‘8828283095aff1fff’，‘882828309585fff’，‘882830821dfff’，‘882828309519fff’，‘882828309519fff’，‘8828308747fff’，‘88282830954fff’，‘8828

当我跑的时候

hexagons = list(h3.polyfill(poly2, 10))

我得到了

[]

为什么会这样呢？

Answer 1

显然，h3只与具有EPSG 4326的投影WGS84一起工作。在poly2中提供的坐标确实有另一个投影！转换坐标，它将按预期运行。
