Local tangent plane coordinates

http://dbpedia.org/resource/Local_tangent_plane_coordinates

Local tangent plane coordinates (LTP), also known as local ellipsoidal system, local geodetic coordinate system, or local vertical, local horizontal coordinates (LVLH), are a spatial reference system based on the tangent plane defined by the local vertical direction and the Earth's axis of rotation.It consists of three coordinates: one represents the position along the northern axis, one along the local eastern axis, and one represents the vertical position. Two right-handed variants exist: east, north, up (ENU) coordinates and north, east, down (NED) coordinates.They serve for representing state vectors that are commonly used in aviation and marine cybernetics. rdf:langString
NED座標(NEDざひょう)とは、North-East-Down(北-東-下)の三方向を正とする三次元の座標系のこと。局地水平座標系とも呼ばれる。 rdf:langString
大地坐标系是由大地经度和大地纬度构成的坐标系。 由右图所示,P点的NPS与起始子午面NGS所构成的二面角L,叫做P点的大地经度,由起始子午面起算,向东为正,叫东经(0度~180度),向西为负,叫西经(0度~180度)。P点的法线Pn与赤道面的夹角B,叫做P点的大地纬度,由赤道面起算,向北为正,叫北纬(0度~90度),向南为负,叫南纬(0度~90度)。在该坐标系中,P点的位置用L,B表示,如果点不在椭球面上,表示点的位置除L,B外,还要附加另一个参数——大地高H。 * 大地坐标系和子午面直角坐标系的关系: * * * 式中,a为地球椭球的长半轴,e为地球椭球的第一偏心率 ,B为大地纬度。 * 大地坐标系和空间直角坐标系的关系: * * * * e'为椭圆的第二偏心率 ,B为大地纬度,L为大地经度,a、b为地球椭球的长、短半轴。 rdf:langString
