GEOS

geos convert linestring to polygon by GEOS

Installation

The project depends on geos (GEOS is a C++ port of the ​JTS Topology Suite), you need to complete the installation of geos first. The installation of geos:

1. Mac OS X(via brew)

$ brew install geos

2. Ubuntu or Debian

$ apt-get install libgeos-dev

3. Build from source code

$ wget http://download.osgeo.org/geos/geos-3.9.0.tar.bz2
$ tar xvfj geos-3.9.0.tar.bz2
$ cd geos-3.9.0
$ ./configure
$ make
$ sudo make install

Usage

go run main.go geos -h


Usage:
  gmaps2 geos -f 'input/linestring.json' -s 2 [flags]

Flags:
  -f, --file string     json source for geo convertion
  -h, --help            help for geos
  -s, --sample string   example operation in integer (s=1,2,3)
