イプシロン３号機の軌道KMLをWolframCloudで描画してみる。

ReliefMapの方がきれいだけど日当たりの状況がわかりにくいので...

　　　画像を貼ってしまったが秒は13ではなく11だったので訂正必要　↓
なお、表示している軌道は地球表面へ投影した状態。

自分でWolframCloud上で試したい人のためにKMLデータを代入するところも含んだ全てのソースを貼っておく。KMLには時刻情報も含めているのでアニメーションも作れるはず。少し加工すればKMLファイルに復元することも可能。

以下コピペ用ソースのすべて。貼り付けてShift+Enterで実行される。
慣れた人ならもっとエレガントに書けると思う。

というか、テレメータ等で取得した本物の軌道データ、欲しいなぁ...
森田先生お願いします。　　m（..）m
