This command sends help information to the standard output according to its argument, one of: datums, formats, help, projections, protocols, transfs.
show datums prints the names of, and existing comments on the available datums.
show formats prints a table of the data file formats known to GPSMan and that can be used in other commands. An example is
EasyGPS: Read, WP Fugawi: Read, WP GD2: Read, WP RT TR GPSMan: Read/Write, WP RT TR LN, Data GPStrans: Read/Write, WP RT TR GPX: Read/Write, WP RT TR, Data GTrackMaker: Read, WP RT TR, Data IGC: Read, TR Parameters Read: alt gps Kismet: Read, WP Parameters Read: group 0 MapGuide: Read, RT Parameters Read: version 2002 idno commt rem MapSend: Read/Write, WP RT TR Meridian: File type invalid NMEA: Read, TR Shapefile: Read/Write, WP RT TR LN Parameters Read: dim 3 pformat DDD zone datum WGS 84 dunit m aunit m Write: dim 3 pformat DDD datum WGS 84 dunit m aunit m
For each known format either there is an indication that the format is invalid (because, for instance, a library as missing or there is incompatibility with the receiver brand), or there is information on the possible read/write operations and item types which will be followed by "Data" if a file may contain items of different types. Parameters may appear followed by their default values if any.
show help prints the accepted commands and options.
show projections prints information on the available projections. For each projection there is the name to be used as argument to commands, a long name, and the list of accepted parameters. For each parameter the name to be used in a command, a type and a short explanation are given. An example is
Stereogr: Stereographic Parameters ?datum lat0 (lat) Lat of centre long0 (long) Long of centre k0 (float>0) Scale factor
meaning that the stereographic projection should be spelt Stereogr in commands, may have a datum=NAME parameter, and must have 3 other parameters under the names lat0, long0 and k0, respectively a latitude, a longitude and a positive floating-point number, standing for the coordinates of the centre of the projection and for the scale factor.
show protocols
prints a list of known protocols that can be used with the
-prot
option. A possible list is
Garmin (Garmin) Garmin_USB (Garmin) NMEA (Garmin) simul (Garmin) SText (Garmin)
showing at the end the receiver brand with which they must be used.
show transfs prints the list of available coordinates transformations with their names to be used in commands and longer names.
