Simple implementation of the Visvalingam-Wyatt algorithm

Project Description

Simple python implementation of a famous algorithm : the Visvalingam-Wyatt simplification.

Installation

Using pip

$ pip install visvalingam

You can download the source using

git clone https://github.com/milkbread/Visvalingam-Wyatt.git

Examples execution

The whole example is located in the example/ directory

$ cd example

Script usage

Dummy

$ python simplify.py -i <inFile> -o <outFile> -t <tolerance>

Example

python simplify.py -i in.json -o out.json -t 0.0005

Help

python simplify.py -h

View results in browser

This is an exemplary workflow for tests :

  • Download the repository

  • Simplify your data

    python simplify.py -i in.json -o out.json -t 0.0005
    
  • setup local server (necessary for D3.js)

    python -m SimpleHTTPServer 8888
    
  • open in browser: http://localhost:8888/index.html

  • If needed adjust the filenames within the example/index.html (lines 24 & 28)

  • evaluate the resulting data and try another threshold
