## Synopsis

A Rust crate use for performing coordinate transformations. The crate relies on nalgebra vectors to perform the coordinate transformations.

## Code Example

`let` ellipsoid `=` `geo_ellipsoid``::``geo_ellipsoid``::`new`(``geo_ellipsoid``::``WGS84_SEMI_MAJOR_AXIS_METERS``,`
`geo_ellipsoid``::``WGS84_FLATTENING``)``;`
`let` lla_vec`:` `Vector3``<``f64``>` `=` `Vector3``::`new`(``3.``0``,` `4.``0``,` `5.``0``)``;`
`let` ecef_vec `=` `lla2ecef``(``&`lla_vec`,` `&`ellipsoid`)``;`
`assert_approx_eq!``(`ecef_vec`.`x`,` `4127585.``379918784``)``;`
`assert_approx_eq!``(`ecef_vec`.`y`,` `4779006.``1975849345``)``;`
`assert_approx_eq!``(`ecef_vec`.`z`,` `894117.``5572814466``)``;`

## Features

- Simple, one line function calls to convert from one coordinate system to another
- Common geodetic models provided for geodetic coordinate transformations
- Uses nalgebra (widely used linear algebra crate)

## Suggestions for use

- Use Rayon! Rayon allows for easy parallelization - which coordinate transformations are an ideal candidate for. Take a look at examples/benchmarking for an example.

## Roadmap / Ideas

- Asserts/Option return for invalid input data

## Examples

There are very early work in progress examples being built. These contain basic examples, benchmarking, and other types of examples to help aid in use of the crate. To run an example from the /examples directory:

`cargo`` run`` --`release` --`example `<`FILE_NAME_HERE`>`
