Can I do these things with Mapsource?

I just got back from the Southwest US where my 76CS was put to use in saving
tracks and waypoints for later overlay on to the Mapsource TOPO program on
my PC. Given that we were out in the field the whole time (we covered about
1000 miles in three days) I had to save all the tracks and waypoints before
I could get back to my machine.

Interesting thing I learned: while the 76CS can store up to 10,000
"breadcrumbs" in its tracking capability, you can only get all of those if
you download that track to the Mapsource program while the track is still
live. Once you save the track it will downsample to a maximum of the 500
most representative track points ("breadcrumbs") for each saved track. I'm
sure everyone else already knows this, so I guess it's just an observation
from a noob. Anyway, back to the story...

So I get back to my room and download to Mapsource. I can't figure out how
to do something. What I'd like to do is be able to "turn on" or "off"
selected tracks and waypoints so that I only see what I want to show as
important for a given part of a day. I'm hoping this isn't going to be
tedious.

Tony,
To the best of my knowledge there is no way to selectively turn on/off
certain waypoints or tracks using Mapsource. The best you can do with that
software is to open more than one instance of Mapsource and copy some of the
data to other mapsource files and then switch between files.

Regarding saving your tracks: I find it convenient to record tracks at a set
time interval. For example with the tracklog set to record a point every 20
seconds, the 10,000 point tracklog will take about 55.5 hours to fill. For
a three day trip that should be enough to record all of your movements as
long as you take some time to sleep. If not sleeping, then set the interval
to 30 seconds, and you will get 83.33 hours of recording.

Tom, can you explain how to copy data from one instance to another?

Tony,
For waypoints: select the waypoint tab in the left pane of the Mapsource
window and select the waypoints you want by control-click or shift-click,
then copy, go to the other instance of Mapsource and paste. With track logs
you do the same thing, but select the logs under the tracks tab. To copy
just part of a track, double click on the log of interest, click and
shift-click to select the portion of interest, go to the other instance of

Thanks for this info, Tom. I started playing around and found another way to
get essentially the same result. As I saved off one gdb file that has
everything in it, I used that as a "master" and just deleted whatever bits I
didn't want to show for a given track/set of waypoints. I then saved that
off as a new gdb. I went back to the master each time to generate all the
views that I was interested in showing. Seemed to work okay.
