Garmin gps maps
 

Hi all;
I am an happy owner of Oregon 550t and I would like to know which method or guide to follow to visualize on the gps more independent tracks pieces simultaneously and together with the preloaded map.
The problem is that if I load these tracks pieces as a single track (since in this gps is not possible to view more tracks at the same time), all the final parts of the pieces are connected with the beginning of the following piece making the vision very difficult.
For this reason I would like to to convert the track to a map and then import it in the gps and put on top of the preloaded map.
As an alternative i could first download the preloaded map from the gps to the pc, insert the track and import everything again.
Note that is not important that the gps follow this track, It could only show it for example like a river; I don't need any navigation function but only see the track with no connecting lines between the pieces.
Does someone of you know the procedure to do this as simple as possible?
All what I have now are hundreds of tracks in .plt or .gpx format not joined and tens of km one far from the other; I must visualize all of them and togheter with the preloaded map.
Thank you for every suggestion.

You probably want to make a transparent map out of your tracks. Check out the wiki on malsingmaps.com and NZ Open GPS Project • View topic - Tutorial Index - Start here for map-making infomation You can find other sites dedicated to map making. To load your maps into Mapsource and to be able to load them into the GPS together with your usual maps you also want something like ezMS.

Consider contributing some of your tracks to projects like OSM.org or Wanderlust.

modifying gps maps
 

Hi,

I use Mapwel software to modify gps garmin maps.
It´s quite simple to use and you don't need any other tool.
