edist¶
Simple command line coordinate processing¶
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.

final-bearing¶
Calculate final bearing between locations.
| -g, --string | Display named bearings. |
| -h, --help | Show this message and exit. |
flight-plan¶
Calculate flight plan for locations.
| -s <speed>, --speed <speed> | |
| Speed to calculate elapsed time. | |
| -t <format>, --time <format> | |
| Display time in hours, minutes or seconds. | |
| -h, --help | Show this message and exit. |
range¶
Check locations are within a given range.
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 -l Home -l Cambridge distance.
BUGS¶
None known.
