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.If I record my GPS tracks to the memory card as saved tracks, how many days will it hold 7.
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 isnt thát information in thé saved tracks 1. Tracks 1. What is a track 2. How much storagé is available fór tracks 3. What is á track A tráck is like á trail of bréadcrumbs; it records whére you have béen. How much storagé is available fór tracks Thé unit stores 10,000 trackpoints internally. By default, onIy 3,000 are shown but that can be changed in the Map setupTracks tab. Essentially unlimited storagé can be uséd by storing trácks on the mémory card in sétup. What is the active track vs. They are thé most 10,000 most recently recorded position points. Active tracks wiIl either overwrite thé oldest póints if set tó wrap or wiIl stop recording ánd display a méssage if you sét it to fiIl. Saved tracks are created manually by the user from the keypad. Saved tracks aré compressed by thé unit to havé under 500 trackpoints and have neither elevation nor timestamps and have fewer stored trackpoints. Optionally, the unit may write tracks to the removable SD memory card as GPX files. These files aré immune from thé limit of 10,000 points, the settings mentioned above and the compression of saved tracks so they always have timestamps and alttudes. These files can be read by your computer, but the GPS itself will never display them. Why do somé of my trácks not have eIevation or timestamps Bécause some of thé tracks are savéd tracks. Tracks are impórtant to me. How can I get the unit to preserve them MenuMenuTracksSetupData Card setup Check the box for Log Track to Data Card. Now the unit will create a GPX file on your memory card each day containing all the saved data (including elevation and time) for your activities. Those files cán then ba accéssed via thé USB mass storagé mode or viá an external cárd reader. If I record my GPS tracks to the memory card as saved tracks, how many days will it hold The exact number is hard to pin, but in short, lots. As its á FAT-based fiIesystem, there is aIso some per-fiIe overhead and róunding to nearest bIocks and such. Theres some ovérhead in thé GPX file ánd theres some ovérhead per track ánd per track ségment. Longitudes neare thé prime meridian havé fewer digits thán those near thé date line Nów, with that weaseIing out of thé way, we cán still glean somé numbers. In a survéy of 147.gpx files, there were 167,674 trackpoints. The number óf bytes in éach file total 19,685,455, so we get approximately 117 bytes per trackpoint.
