Traillink.com is an excellent source of trail information. Here is a link to their Highline Trail web page:

https://www.traillink.com/trail/high-line-canal-trail-(co)/

They also have a downloadable .GPX file for the trail which you could modify with your own data via the programs I mentioned in an earlier post.

You have to be a member of Traillink to view maps and download files though. If you are a serious trail rider like I am, it is well worth the $25 / yr. subscription fee.

I just joined TrailLink yesterday, and the subscription was $30, not $25. They have apparently raised prices since you last paid. Also, when you first join the TrailLink.com site, it is kind of confusing about what is a subscription (what they call "unlimited" access) and what is a contribution to the Rails-To-Trails Conservancy, so be careful about what you are paying for. That said, it does appear to be a great resource with lots of valuable information.

I assume they do no include any eBike specific information?

This site is GPX specifically for eBikes. They appear to retain and display battery level information.

Based on the Bosch Range Estimator, i should be able to ride the length of the Highline Canal trail on one battery. A second battery would be needed for the return trip. If this is true, then eBikes are becoming significant. The Highline Canal trail cuts across Denver from one corner to the opposite corner.

TRip Analyzer - seems a little too low level. Appropriate for engineers.

Google Maps Tricks
Google Maps created by GPS Visualizer can be customized as much as you want. Not everything is documented in detail, but here are a few example maps that demonstrate some of the possibilities:

• Folders in a marker list - Organize your waypoints/markers into "folders" that can be collapsed and/or hidden with a click.
• More fun with folders - In this example, the folder names were "synthesized" from existing fields in the input data.
• Filter markers with a text pattern - Set up links that cause only certain markers to be shown on the map.
• Google Docs/Drive Spreadsheet - Create a map whose markers are loaded on-the-fly from an online spreadsheet.
• Dynamically loaded GPX or KML - Put a GPS data file (in GPX or KML format) on your site, and have the map load the tracks and waypoints dynamically.
• Database-driven map - Markers are loaded from a MySQL database and updated when the map's viewport is moved.
• Geotagged photos - Make a map of the locations of geotagged photos, including thumbnails.
• Custom map backgrounds - Add to or alter the "map type" menu.
• Geolocation - Center a map on the viewer's current position.

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 might need to be organized a little bit before being processed, and that's where these tutorials come in.

• 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.
• Calculating Elevation Gain
  Learn why elevation gain is so difficult to get right, and how GPS Visualizer can help.
• 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).
• Drawing circles/range rings around waypoints
  GPS Visualizer can draw circles of a specific radius around your points, allowing for definition of circular ranges or triangulation between points.

GPS Visualizer can read data files from many different sources, including but not limited to: GPX (a standard format used with many devices and programs, including

• Garmin's eTrex,
• GPSMAP,
• Oregon, Dakota, Colorado, & Nüvi series),
• Google Earth (.kml/.kmz),
• Google Maps routes (URLs),
• FAI/IGC glider logs,
• Fugawi (.trk/.wpt), Furuno,
• Garmin Fitness (.fit)
• , Garmin Forerunner (.xml/.hst/.tax),
• Garmin MapSource/BaseCamp/HomePort (.gdb),
• Geocaching.com (.loc),
• Google Spreadsheets,
• IGN Rando (.rdn),
• iGO (.trk),
• Lowrance (.usr),
• Microsoft Excel,
• NMEA 0183 data
• , OziExplorer (.plt/.wpt),
• Suunto X9/X9i (.sdf),
• Timex Trainer,
• TomTom (.pgl),
• U-blox (.ubx),
• XML feeds,
• and of course tab-delimited or comma-separated text.

GPS Visualizer is based in Portland, Oregon, and has been on the Web since October 2002.

This PDF gives you a rough idea of battery performance parameters.

(Link Removed - No Longer Exists)

During winter use (particularly below 32 ̊ F (0 ̊ C)) we recommend charging and storing the battery at room temperature before inserting the battery in the eBike immediately before riding it. For frequent travel in the cold, it is advisable to use thermal protective covers.

My understanding is you can easily overlay battery status onto a map by taking pictures of the bike head unit with a phone that takes pictures in EXIF format, e.g., iphone.

• 
  
• https://wiki.openstreetmap.org/wiki/Recording_GPS_tracks
• If you want to update the OSM map yourself afterward, take what you need to record the details of what you encounter along your track — notepad, voice recorder, digital or video camera, etc. Software such as JOSM will allow you to synchronize your recordings with your path, for example, place the pictures on the map where you took them.
• One could also just take photos along the route. You may get the latitude and longitude and the original date time by reading EXIF information from photos you have taken. Generate gpx file(an xml format) either manually of by programming in the proper format for gpx file and test it by opening with JOSM to make sure the gpx file is proper formatted, and then you may be able to load gpx file using web interface or by JOSM upload plugin.

Apple solution for geocoding a picture onto a map may be cumbersome or confusing with the Preview and Maps apps. I am disappointed with Apple for regressing so much.

Have you ever reset a car trip odometer to calculate MPG after filling a tank? Same technique for a battery. Cell phone pictures of the bike computer head unit becomes the trip odometer.

First, if you simply want to analyze your battery economy using your cell phone to display battery charge on a map, take pictures of the bike computer. You can also display any other bike computer information by exploiting the GPS data stored in a picture. Geocoding your experience on a map can simply be a picture that captures that moment.

Using a cell phone to compare the eBike battery economy of different bikes is particularly useful when buying a new eBike.

Seems like some Mac apps exist to process GPX files, which might be more productive.

I cannot believe Apple has regressed this far. I took a screen shot of Maps and pasted the picture next to the map pin. The picture could be of the eBike head unit displaying battery status or any other information.

Perhaps, I need to start wearing glasses, rather than contacts, when I ride my bike so I can read the iPhone. Or, only wear glasses to learn a route. I hate to burn down my battery by using Google turn by turn GPS directions.

I can try wearing just one contact, as opposed to wearing both contacts. I think that might be the best compromise. I do want the pictures geocoded onto a map without hassle.

Using the phone takes on greater importance when i want to geocode experiences on the map. I need to take screenshots of the phone to fully express an experience. A screenshot is a way to print text information into a geocoded picture.

I already own the GAIA iPhone app that geocodes pictures, as illustrated in the following screenshot:
