## What is pprepair?
-pprepair (*p*lanar *p*artition repair) takes a set of polygons and ensures that they form a valid planar partition, made of valid polygons and having no gaps or overlaps. It can be used as a validator, telling of problems in individual polygons or in the planar partition, and also as an automatic repair tool, outputting a set of polygons that do form a valid planar partition.

In short, pprepair creates a constrained triangulation of the polygons, tags each triangle with the polygon that it belongs to, modifies the triangulation to ensure that only one tag is present in each, and reconstructs the polygons from the triangulation.

To compile pprepair, you first need to install the free libraries [CGAL](http://www.cgal.org) and [GDAL](http://www.gdal.org). [CMake](http://www.cmake.org) is highly recommended. Under Mac, we recommend using [Homebrew](http://brew.sh/) to install CGAL (and all its dependencies) and CMake, and GDAL is easily installed with the framework installed of [KyngChaos](http://www.kyngchaos.com/software/frameworks#gdal_complete).

+To install it, run (inside the root of the source tree):
- $ cmake -DDRIVER="ESRI Shapefile" .
+ $ mkdir build
+ $ cd build
+ $ cmake ..
$ make

+Eventually, you can edit the CMakeLists.txt file to use a different OGR driver for output files (e.g. GeoJSON or ESRI Shapefile).

- If your data set has very large polygons, try passing the -bd flag
- If your data set has points that are **very** close together, try uncommenting line 26 in definitions/CGALDefinitions.h (#define EXACT_CONSTRUCTIONS)
