CL-PROJ: Lisp bindings for the Proj.4 library

=============================================

PROJ.4 is a cartographic projections library originally written by

Gerald Evenden then of the USGS. PROJ.4 has been placed under an MIT

license.

CL-PROJ provides CFFI-based Common Lisp bindings for the PROJ.4

library. It is placed under the Berkeley Software Distribution (BSD)

license meaning that you can do almost everything you want with it.

PROJ.4 homepage is: [proj4.org](http://proj4.org/)

Original CL-PROJ homepage was at the

[cl-proj.sourceforge.net](http://cl-proj.sourceforge.net/), but

current development and documentation is [at the

Bitbucket](https://bitbucket.org/vityok/cl-proj).

`cl-proj` can be installed using the

[Quicklisp](https://www.quicklisp.org/) system:

    (ql:quicload :cl-proj)

Usage

=====

Library loading and linking into the Lisp image is performed

automatically when it is loaded by ASDF/QuickLisp.

Symbols are defined in the `cl-proj` package and are also available

using the `pj` package nickname.

Constants, variables and functions are extremely close to the

PROJ.4. Bindings for geodesic functions are also provided in addition

to the core Proj4 API. Reference is in the  file that is

supplied in the distribution.

Primary development platform is recent Ubuntu Linux distribution with

recent versions of SBCL and ECL Common Lisps.

In addition to Proj4 library bindings this package a number of utility

functions, including:

* Parsing degrees from a string and conversion between

  degree-minutes-seconds and decimal representations

* Simplification of polygons/polylines (reducing number of vertices)

  using the Ramer–Douglas–Peucker algorithm

* Projecting points from a geographic space onto a screen with the

  given dimensions and viewport

* Construction of circular lines with the given radius and center

  (like missile ranges, etc.)

This package has been used to produce some maps in the

[collection-of-maps](https://bitbucket.org/vityok/collection-of-maps)

([Wiki](https://bitbucket.org/vityok/collection-of-maps/wiki/Home)).
