One question
When the coordinates was re-calculated from local datums to WGS84, may be coordinate Z (altitude) was omited ?
Usually is used the altitude from RA and barometric for the landing (1990's), but now DGPS altitude is used (the sentence $GPGGA , corrected WAAS etc).For example, handheld Garmin , we can choose more than 100 datums and the accuracy ,especially height, will better.
