# GeographicLib.jl

Julia port of Charles F. F. Karney's [GeographicLib](https://geographiclib.sourceforge.io).

## About

GeographicLib allows you to accurately compute properties of

[geodesics](https://en.wikipedia.org/wiki/Geodesic) on a flattened sphere (e.g., Earth).

## Documentation

For full details of using the package, see the

[latest documentation](https://anowacki.github.io/GeographicLib.jl/dev).

## Testing

To perform some of its tests, the package relies on the Python port of GeographicLib.

Hence if you do `pkg> test`, PyCall will attempt to import `geographiclib` and

install it if possible.

You may also run `julia script/test_GeodTest.jl` which compares the output of this

package and the routines in `libproj` to a set of test results computed with

high precision.  For this purpose, you need to have

[Proj installed](https://proj.org/install.html) and will need to edit the script

to point to the location of the `libproj` library.

Neither of these tests are necessary to use GeographicLib.jl normally.
