Turn GPS tracks, routes and waypoints into a fast, streamable FlatGeobuf file. Free, private and processed right in your browser.
Three steps, no software to install. Works on Windows, macOS, Linux and mobile.
01
Drop a .gpx file into the converter, or click to browse. Files up to 100 MB are supported.
02
Click Convert to FlatGeobuf. The file is processed locally, so your data is never uploaded to a server.
03
The FlatGeobuf file downloads straight to your device. Need another format? Pick a converter below.
Converted your GPX file? Upload it to GISCARTA and turn it into an interactive map your team or clients can actually use.
Colour by attribute, cluster thousands of points, switch on 3D.
Charts and key numbers next to the map, updated as you filter.
Animate dated features and compare how places change.
Publish a read-only map, embed it on your site, or keep it private with role-based access.
No credit card. No GIS degree. Upload your data and start mapping in minutes.
GPX is built for exchanging GPS data between devices and apps. FlatGeobuf is built for large datasets and cloud-native web maps.
GPX
GPX (GPS Exchange Format) is an open, XML-based format for GPS data. A single file can hold waypoints, routes and tracks, with coordinates in WGS84 latitude and longitude.
Almost every GPS device, sports watch and outdoor app exports GPX, which makes it the default format for sharing recorded trips. Because it is plain XML, large track logs get bulky and slow to search.
FlatGeobuf
FlatGeobuf is an open, binary vector format built on FlatBuffers. It stores features with a built-in spatial index, so software can read just the area it needs.
It is one of the fastest formats to read and write, and it can be streamed over HTTP from cloud storage without a map server.
Your GPX file
Waypoints, routes and tracks come through as separate layers; track points keep their elevation and time.
The FlatGeobuf output
The output includes a spatial index, so it is ready for fast bounding-box reads and streaming.
Your file never leaves your device: conversion runs in your browser, for files up to 100 MB.
Open large GPX datasets in seconds instead of minutes.
Host the file on S3 or any static storage and read only the visible map area over HTTP.
Serve GPX features to OpenLayers or Leaflet without running a map server.
Every converter runs in your browser and keeps your files on your device.
