GPSmap 60CSx Request for advice

Posted by dcp on 26 November 2011 in English (English)

I am presently in Cyprus mapping the E4 Cross-European Rambling Route. Unfortunately my Notebook was defect on arrival so I cannot transfer my tracks to Mapsource and hence to OSM. In addition I did not bring my GPSmap 60CSx documentation with me. So here my request for advice.
The GPSmap 60CSx Track Log is about 90% full.
If I Save this Track Log to the micro-SD, will I be able to retrieve it later and transfer it to Mapsource with no negative effect. I ask for this advice as I have never done it before and I do not want to lose the tracks before adding the data to the OSM databank.
I'll be greatefull for any advice and greetings from sunny Cyprus.

Never use the save feature in the GPSmao60Cx, because it will do some optimization which reduce the volume of the data, and you lose som accuracy.
Instead go int to Tracks menu, select Setup, select Data Card Setup,And check the "Log Track to Data Card". this will allow you to recover all subsequent traced tracks with full details from you SD card.

Yes do as ablansinger says. The GPSr makes a file on the data card for every day it is switched on. Today's would be named 20111126 in that file is stored all tracks for the day. No matter how you play with the unit, even resetting the track data has no effect on the track data stored to the card. Resetting track data resets the data within the unit memory.

Thank-you both for the advice. Just to make sure that I understand the system functionality please confirm the following:
The data (i.e. The 90% mentioned above) will not be transferred to the micro-SD but will remain in the RAM. From i.e. tomorrow all the new data will be stored directly to the micro-SD and the RAM will remain at 90% full. That means that my history will not be lost and any new data will be saved with the date as directly to the SD-Card.
Thankyou once again.

Hello,
You obviously have the unit set to record your track log as you say it's 90% full, leave that as it is.
Then yes just set it up as ablansinger says. Then all track/tracks will be recorded in full on the card for a 24 hour period. If you switch the unit on to check say a waypoint a track section will be recorded to the card. If in the middle of a trip you reset the track data another section of track will be recorded, switch the unit off and on, another section is recorded. And so on for the whole day. The unit knows the time of day and will start recording a new days track a second after midnight if it's left on, (mine has on occasion been left on all night). Your track log data will not be optimised in any way.
Regards

The Tracklog ( the 10,000 point limit ) on the Garmins is independent of what is stored on the data card. The data card is always storing data at the rate you specify in the menu, eg every 1 second, every 10 meters etc.

The tracklog's only function is to allow you to track back to where you came from. If you set the Garmin to log every second this gives you just under 3 hours of track back time, though this function is not relevant for most mappers. Ignore the Tracklog ( unless you really need it, your data is on the SD card at all times ( so long as you have set the menu to store to card ). You can set the Tracklog to wrap around, or stop at 100 %, either way this does not affect the logs on the SD card which are always being cached at the rate you specify.

Re the saving of tracks, The Garmins use an optimisation / compression algorithm to minimise the size of saved tracklogs reducing accuracy ( for mapping purpose ) so is generally avoided for caching.

Thank you all for the advice/information. Please clarify the following.
From now on the tracks and the associated waypoints will both be saved to the sd-card on a daily bassis. This assumes that I have set the wrap-around function to OFF and the TRACK-To-SD-CARD to ON.

Hello,
Set the unit to "Log Track to Data Card" (as above) and all track waypoints will be recorded to the SD card, other waypoints ie POI, car, hotel are held on the units memory as usual.
The wrap around function only has a relation with the unit memory, hence the need for wrap around. Wrap around (on or off) has no effect on the SD card recording.
Get out and enjoy that sun, it's cloudy and gusting to gale force winds here in the east of England.
Regards
