Are you feeling bloated, or at least are your GPX track files feeling bloated? Then read on.
Sian Lambert posted on the Audax FB group a few days back about her GPX file being rejected by the AUK mandatory route form because it was too large / bloated. It became clear not many know how to reduce the size of their GPX or even if they do they find it quite hard to get right.
I've taken something I've been doing for years to slim down GPX files and converted it into a simple one page web site / application.
All you need to do is select a GPX file on your computer, and a tolerance. A new slimmed down GPX based on the tolerance will be returned to you in zip format .
Some sample outputs for a 200km track
1m tolerance - .209KB (58KB zipped) about 3200 track points
5m tolerance - 93KB (27KB zipped) about 1400 track points
10m tolerance - 61KB (19KB zipped) and about 900 track points
20m tolerance - 42KB (13KB zipped) and about 600 track points
50m tolerance - 23KB (7KB zipped) and about 300 track points
100m tolerance - 15KB (4KB zipped) and about 200 track points
I'm hosting it on a free server and it's free to use. Use at your own risk and I certainly recommend putting the slimmed down GPX back into a mapping program to make sure you are happy with the result.
Because it's a free server, performance will be what it is, but unless a great number of you hit it at the same time it should process your GPX in a timely manner.
