Etrex vista hcx track points

When I try "Where to", the closest choice is Trac-Back, and it will only allow you to use the LAST segment of track, even if that isn't the complete trip you'd like to do. It then converts it to a route so as to provide turn-by-turn directions. I'm starting to suspect that none of the current Nuvi's can read tracklogs stored on the SD card, and the doesn't handle custom trail maps well.

Sort of rules them out for my applications. I don't think one Garmin programming team ever talks to the next one. The really should have the same software as an Oregon. First to communicate my garmin I use BaseCamp, so to import a trail let say one that I made on Google Earth, I draw it and save as into a familiar folder so now I have it on.

I then open on the track on the BCamp Map and than with the mouse I go on top of the track and you right click it and you choose open, now a window appears with all the points in it, Click the filter button and filter it until the desired size under is achieved en presto send it to you unit and your done..

All Activity Home Geocaching and Track Truncated? Followers 0. Reply to this topic Start new topic. Recommended Posts. Posted March 8, Hi, tonight I downloaded 39 full resolution tracks that cover the Appalachian trail.

I have a Garmin etrex vista hcx. Link to comment. MtnHermit Posted March 8, Posted March 8, edited. The reason the files were truncated was the HCx has a point limit. Edited March 8, by MtnHermit. Bob Morphew Posted March 8, Posted March 9, If you need to filter the tracks down to points, Mapsource has tools to do this for you.

Reply to this topic Go to topic listing. As it's a FAT-based filesystem, there is also some per-file overhead and rounding to nearest blocks and such. There's some overhead in the GPX file and there's some overhead per track and per track segment. As the data is stored as readable text, each individual trackpoint may even vary in size - for example elevations in the mountains have more digits and thus consume more space than elevations near sea level.

Longitudes neare the prime meridian have fewer digits than those near the date line. Now, with that weaseling out of the way, we can still glean some numbers. In a survey of The number of bytes in each file total 19,,, so we get approximately bytes per trackpoint. That comes to almost 9, trackpoints per megabyte.

So if you have the unit set to record trackpoints at the maximum rate of 1 per second and are logging around the clock, budget about 10MB of track data per day. New files will be created at midnight GMT. When I look at the GPS, it knows the temperature reported by my marine sensor, the heading reported by my compass, and the wather depth reported by my depthfinder.

Why isn't that information in the saved tracks? That's a lovely question for Garmin. The reality is that the saved tracks - whether internal or as GPX on a memory card - contains none of that info. Tracks 1. What is a track? How much storage is available for tracks? What is the active track vs. Why do some of my tracks not have elevation or timestamps? Tracks are important to me.
