print "\nThis $scriptname script creates location data
for a range/altitude view which can be displated in a modified
fork of dump1090-mutability or Google Earth / Maps.
The script creates two output files:
rangeview.csv) A file with location data in CSV format can be
imported in to tools like http://www.gpsvisualizer.com.
rangeview.kml) A file with location data in KML format, which
can be imported into a modified dum1090-mutability or Google
Earth / Maps.
This script uses the output file(s) of the 'socket30003.pl'
script, which are by default stored in /tmp in this format:
dump1090-<hostname/ip_address>-YYMMDD.txt
It will read the files one by one and it will automaticly use
the correct units (feet, meter, mile, nautical mile of kilometer)
for 'altitude' and 'distance' when the input files contain
column headers with the unit type between parentheses. When
the input files doesn't contain column headers (as produced
by older versions of 'socket30003.pl' script) you can specify
the units.Otherwise this script will use the default units.
The flight position data is sorted in to altitude zones. For
each zone and for each direction the most remote location is
saved. The most remote locations per altitude zone will be
written to a file as a track.

Syntax: $scriptname
Optional parameters:
-data <data directory> The data files are stored in
'$datadirectory' by default.
-log <data directory> The log files are stored in
'$logdirectory' by default.
-output <output The output file is stored in
directory> '$outputdirectory' by default.
-file <filename> The output file name. The extention
(.kml or .csv) determines the
file structure!
'$outputdatafile' by default.
-filemask <mask> Specify a filemask.
The default filemask is '$filemask'.
-override Override output file if exists.
Default is '$override'.
-timestamp Add timestamp to output file name.
Default is '$timestamp'.
-sequencenumber Add sequence number to output file name.
Default is '$sequencenumber'.
-max <altitude> Upper limit. Default is '$max_altitude $altitudeunit{'out'}'.
Higher values in the input data will be skipped.
-min <altitude> Lower limit. Default is '$min_altitude $altitudeunit{'out'}'.
Lower values in the input data will be skipped.
-directions <number> Number of compass direction (pie slices).
Minimal 8, maximal 7200. Default = '$number_of_directions'.
-zones <number> Number of altitude zones.
Minimal 1, maximum 99.
Default = '$number_of_altitudezones'.
-lon <lonitude> Location of your antenna.
-lat <latitude>
-distanceunit <unit>,[<unit>]
Type of unit: kilometer, nauticalmile,
mile or meter. First unit is for the
incoming source, the file(s) with flight
positions. The second unit is for the
output file. No unit means it is the
same as incoming.
Default distance unit's are:
'$distanceunit'.
-altitudeunit <unit>[,<unit>]
Type of unit: feet or meter. First unit
is for the incoming source, the file(s)
with flight positions. The second unit
is for the output file. No unit means it
is the same as incoming.
Default altitude unit's are:
'$altitudeunit'.
-debug Displays raw socket messages.
-verbose Displays verbose log messages.
-help This help page.
notes:
- The default values can be changed within the config file 'socket30003.cfg'.
- The source units will be overruled in case the input file header contains unit information.
