heatmap-parse

GPS track processor for frequency-based route heatmaps from GPX, FIT, and polyline data.

Features

• GPX file parsing
• FIT file parsing
• Polyline decoding
• Route frequency analysis
• WebAssembly bindings

Usage

Rust

use heatmap_parse::{process_gpx_files, decode_polyline, process_polylines};

let files = vec![/* Vec<u8> file data */];
let result = process_gpx_files(files);

let coords = decode_polyline("_p~iF~ps|U_ulLnnqC_mqNvxq`@");

let polylines = vec!["polyline1".to_string(), "polyline2".to_string()];
let tracks = process_polylines(polylines);

WebAssembly

import init, { process_gpx_files, decode_polyline_string } from 'heatmap-parse';

await init();

const files = [/* Uint8Array buffers */];
const result = process_gpx_files(files);

const coords = decode_polyline_string("_p~iF~ps|U_ulLnnqC_mqNvxq`@");
