I have a Garmin GPS76 which I use when walking in the Scottish hills, mainly to record a tracklog for posterity. I deliberately didn't buy the mapping version of this unit as the maps available from Garmin aren't much good for my intended use. When I saw stuff about GPSmapper in sci.geo.satellite-nav I didn't take much notice as I didn't have a mapping receiver. It was only when "Snay" posted an announcement of GlobGPS which included a mention of POI memory that I started to take notice.
The results are here, in the form of text files of POI data for feeding to cGPSmapper for Munros, Tops and now also for Corbetts.
I'm a command line person myself, and I couldn't get the stuff about dragging and dropping icons on shortcuts as descibed in the GPSmapper Getting Started document to work. I did this:
What I wanted to do was have the Munros visible at a different zoom level from the Tops, so as you zoom the map in the Munros appear first and then the Tops as you zoom in further. This would avoid too much clutter when things first appear. I obviously don't undersand the stuff about visibility at various zoom levels well enough though as I couldn't get this to work. That's why I have ended up using three .img files, so I can enable the display of Munros, Tops and Corbetts separately. I have used .img filenames based on ISO 8601 dates, with a couple of digits for a serial number. I would normally avoid two digit years in dates like the plague but as I only have eight characters to play with I don't have much choice. Having all numeric names is currently important as the title doesn't show up in the map menu otherwise (and when it does appear it appears twice). This will presumably get sorted out in a later version of GPSmapper.
GPSmapper only seems to understand coordinates in lat/lon form so I had to convert the Ordnance Survey grid references I had into this form, and if I was going to do that I might as well convert to WGS84 datum as well as all the GPSmapper documentation used this. I did this by creating a file of waypoints in OS grid format and using MacGPS Pro (my normal tool for GPS stuff) to load that into the GPS76. I then switched both the GPS76 and MacGPS Pro to WGS84, ddd.dddd format, and fetched them out again.
I would like to say a big thank you to the people behind GPSmapper, and to Snay for documenting it. In particular I would like to thank them for using text based input. I haven't used the actual GPSmapper program at all, only cGPSmapper and sendMap. If I had to point and click in a GUI to create the POI list I wouldn't have bothered starting. Note that I said text based, not plain text. I'm convinced XML is the way to go in the future but as my source data wasn't in XML, and neither MacGPS Pro nor GPSmapper use it, it wasn't worth it for this particular job.
