Tutorials

If you have data that came directly from a GPS unit, and you just want to see where you've been, using GPS Visualizer is very easy: you upload the file and you get a map.

For some purposes, though -- including some that take advantage of GPS Visualizer's most powerful features -- the data needs to be organized a little bit before being processed, and that's where these tutorials come in. They're mostly focused on building plain-text comma-separated value (CSV) files or tab-delimited text files -- the kind you would get from a spreadsheet. Assigning a name and coordinates to a point is easy, but what's the best way to assign a color, or a size, or a custom icon? Read on.

  • Building Plain-Text Waypoint Files

    No matter what you're trying to do with your data, read this one first! There are a lot of important concepts in this tutorial that will help when you are reading the others.

  • Building Plain-Text Track Files

    How to force plain-text data to be interpreted as tracks instead of waypoints; how to include multiple tracks in the same file; how to mix in routes and/or waypoints with track data.

  • Smoothing & Simplifying Tracks

    How to use GPS Visualizer's track-smoothing filters to reduce GPS artifacts and create smaller files.

  • Mapping Quantitative Data

    Learn how to take advantage of GPS Visualizer's ability to resize and/or colorize points based on any field in your data, and how to make GPS Visualizer perform automatic frequency counts on your location-based data (e.g., ZIP codes).
