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
