This command sends help information to the standard output according to its argument, one of: datums, formats, help, projections, protocols, transfs.
show datumsprints the names of, and existing comments on the available datums.
show formatsprints 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
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 helpprints the accepted commands and options.
show projectionsprints 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 protocolsprints a list of known protocols that can be used with the
-prot option. A possible list is
Garmin (Garmin) NMEA (Garmin) simul (Garmin) SText (Garmin)
showing at the end the receiver brand with which they must be used.
show transfsprints the list of available coordinates transformations with their
names to be used in commands and longer names.![]()
