SYNOPSIS¶
edist [option]… <command> <location…>
DESCRIPTION¶
edist operates on one, or more, locations specified in various formats. For example, a location string of “52.015;-0.221” would be interpreted as 52.015 degrees North by 0.221 degrees West, as would “52d0m54s N 000d13m15s W”. Positive values can be specified with a “+” prefix, but it isn’t required.
It is possible to use Maidenhead locators, such as “IO92” or “IO92va”, for users who are accustomed to working with them.
Users can maintain a local configuration file that lists locations with assigned names, and then use the names on the command line. This makes command lines much easier to read, and also makes reusing locations at a later date simpler. See CONFIGURATION FILE.
OPTIONS¶
--version | show program’s version number and exit |
-h, --help | show this help message and exit |
- –config-file = file
- Config file to read custom locations from
- –csv-file = csv_file
- CSV file (gpsbabel format) to read route/locations from
-v, --verbose | produce verbose output |
-q, --quiet | output only results and errors |
- -o FORMAT, –format FORMAT
- produce output in dms, dm, d format or Maidenhead locator
-g, --string | display named bearings |
- -u km, –units km
- display distances in km(default), mile or nm
COMMANDS¶
destination
¶
Calculate the destination for a given distance and
-l {square,subsquare,extsquare}, –locator {square,subsquare,extsquare}
accuracy of Maidenhead locator output
-d DISTANCE, --distance DISTANCE | |
distance from start point | |
-b BEARING, --bearing BEARING | |
bearing from start point |
display
¶
Pretty print the location(s)
-l {square,subsquare,extsquare}, –locator {square,subsquare,extsquare}
accuracy of Maidenhead locator output
distance
¶
Calculate the distance between locations
flight-plan
¶
Calculate the flight plan corresponding to locations
-s SPEED, --speed SPEED | |
speed to calculate elapsed time |
-t {h,m,s}, –time {h,m,s}
display time in hours, minutes or seconds
range
¶
Calculate whether locations are within a given range
-d DISTANCE, --distance DISTANCE | |
range radius |
sunrise
¶
Calculate the sunrise time for a given location
sunset
¶
Calculate the sunset time for a given location
CONFIGURATION FILE¶
The configuration file, by default ~/.edist.conf, is a simple INI format file, with sections headers defining the name of the location and their data defining the actual position. You can define locations by either their latitude and longitude, or with a Maidenhead locator string. Any options that aren’t handled will simply ignored. For example:
[Home]
latitude = 52.015
longitude = -0.221
[Cambridge]
latitude = 52.200
longitude = 0.183
[Pin]
locator = IO92
With the above configuration file one could find the distance from Home to Cambridge using edist –distance Home Cambridge.
BUGS¶
None known.
