Thing is, since that time I've been trying to work out a good way of making my own custom maps. I have access to a colour laser and can handle the printing parts fine, but finding the following is proving challenging:
* Software (preferably Free/Open Source) to make said maps, overlay routes, smooth routes and add waypoints.
* Data Sources (although GeoBC seem to be getting close: http://www.newsroom.gov.bc.ca/2013/0...go-mobile.html)
Safety note: Always take a map with you into the backcountry with a compass and knowledge of how to use them. I usually take a third-party/official printed map as a backup to any self made map source and electronic source.
Export your map to pdf first.
when you click print it under "Page Sizing & Handling" click "Poster" button. That will divide you map to small pieces what you may print on you regular color printer and glue them after to one big map.
Quantum GIS (http://www.qgis.org/) is an open source Geographic Information System package that will allow you to download data from GeoBC, overlay GPS points/topography/rivers and publish the outputs to a PDF or image format.
I'm new here, but if you have a specific request I could do up a map (similar to the example you posted). I could include a basic set of instructions since it seems like you're interested in learning the process yourself.
