GeoJSON

This is command line utility which performs three functions:
1. 'area' - outputs boundary area encircling a collection of points given the
minimum distance from all points in a collection. I used it to generate boundary area for a transit application in Apple Store.

2. 'eqdist' - calculates equidistant point based on three geographic coordinates.

3. 'mincircle' - finds "min circle" (minimum bounding circle) based on a collection of input points. This function uses non-recursive randomized Welzl algorithm, applying it to spherical/geodesic case

Note: You will have to supply sample input in form of .csv files to use this utility. Refer to https://github.com/intheswim/geojson for samples.
