data diving station depth length bearing
There is missing from station to station information: From Survey manual: DIVING An underwater survey where the vertical information is from a diver’s depth gauge. This style can also be also used for an above-water survey where the altitude is measured with an altimeter. DEPTH is defined as the altitude (Z) so increases upwards by default. So for a diver’s depth gauge, you’ll need to use *CALIBRATE with a negative scale factor (e.g. *calibrate depth 0 -1). For non-interleaved data the allowed readings are: FROM TO TAPE COMPASS CLINO BACKCOMPASS BACKCLINO FROMDEPTH TODEPTH DEPTHCHANGE (the vertical can be given as readings at each station, (FROMDEPTH/TODEPTH) or as a change along the leg (DEPTHCHANGE)). Survex 1.2.20 and later allow an optional CLINO and/or BACKCLINO reading in DIVING style. At present these extra readings are checked for syntactic validity, but are otherwise ignored. The intention is that a future version will check them against the other readings to flag up likely blunders, and average with the slope data from the depth gauge and tape reading. For interleaved data the allowed readings are: STATION DIRECTION TAPE COMPASS BACKCOMPASS DEPTH DEPTHCHANGE. (the vertical change can be given as a reading at the station (DEPTH) or as a change along the leg (DEPTHCHANGE)). *data diving from to tape compass fromdepth todepth 1 2 14.7 250 -20.7 -22.4 *data diving station depth newline tape compass 1 -20.7 14.7 250 2 -22.4 *data diving from to tape compass depthchange 1 2 14.7 250 -1.7 M.
