緯度経度からメッシュコードに変換するPython script

Last updated at Posted at 2017-01-07

10進数表記の緯度経度からメッシュコードに変換するPython scriptです.
(たまには,communityに貢献しようかと...)

Coordinate2MeshCode.py
def Coordinate2MeshCode( dLat, dLng ):
    # cf: http://white-bear.info/archives/1400
    # Make sure the input values are decimal 
    iMeshCode_1stMesh_Part_p = dLat *60 // 40;
    iMeshCode_1stMesh_Part_u = ( dLng - 100 ) // 1;
    iMeshCode_2ndMesh_Part_q = dLat *60 % 40 // 5;
    iMeshCode_2ndMesh_Part_v = ( ( dLng - 100 ) % 1 ) * 60 // 7.5;
    iMeshCode_3rdMesh_Part_r = dLat *60 % 40 % 5 * 60 // 30;
    iMeshCode_3rdMesh_Part_w = ( ( dLng - 100 ) % 1 ) * 60 % 7.5 * 60 // 45;
    iMeshCode = iMeshCode_1stMesh_Part_p * 1000000 + iMeshCode_1stMesh_Part_u * 10000 + iMeshCode_2ndMesh_Part_q * 1000 + iMeshCode_2ndMesh_Part_v * 100 + iMeshCode_3rdMesh_Part_r * 10 + iMeshCode_3rdMesh_Part_w;
    return iMeshCode;

Kobitoからのuploadテストも兼ねました.

Jan7,2017: 致命的な問題をひとまず修正 (@shiracamusさん、ご指摘どうもありがとうございます)
1. 演算順序のミス
2. 恥ずかしい英語のミス
Pythonというか、プログラマとしてのコードの綺麗な書き方を学んだ方がいいですね、私。。。
演算結果を確認して、続いて修正します
