But they are in GML format (Geography Markup Language) and SHP (ESRI Shapefiles). The latter are probably going to be what I need. But how do I view SHP files? Searches so far have yielded many technical articles but so far no freely available program. Anyone here with suggestions please?

Copied from Help: "GPS Utility exports/imports GPS data in DBF/SHP/SHX filesets. Thus 3 files are exported with the same name, but with extensions *.DBF, *.SHP and *.SHX."
HTH, Mike. -- If reply address is invalid, remove spurious "@" and substitute "plus" where needed.

Thanks Mike. Might have guessed Alan's ubiquitous GPSU supported them!
But I've so far had no success.
I opened one of the SHPs from Geobase using GPSU 4.9t and then, after the data had apparently been imported, tried opening the map window. But GPSU crashed and had to be closed via the XP TM. When I tried another similar SHP, this time by r-clicking the file and choosing Open With > GPSU 4.9t, I had a message that the number of trackpoints had been exceeded. (I didn't try opening the map window this time.)
The only other SHP file I have on my PC (which I have successfully opened in other viewers, albeit with inconsistent results) was this 1.2 MB one: World_countries_shp.dbf 32 KB DBF File World_countries_shp.sbn 9 KB SBN File World_countries_shp.sbx 1 KB SBX File World_countries_shp.shp 1,215 KB ESRI shapefile <--- World_countries_shp.shx 2 KB SHX File
That gave the message 'Import error'. Also, the map window shows just some 'outlines', not a proper map.
I've posted to the GPSU group and if necessary will also seek help from Alan. But if anyone here has any insights I'd appreciate hearing please.

Meanwhile, I'm discovering from trying other SHP 'viewers' that this is a more complex topic than I'd hoped. I have yet to see anything like decent map ;-(

Thanks Wayne. A little earlier this afternoon I'd found and installed ArcGIS ArcExplorer, some sort of Java program. Looked pretty daunting to me and I'm now about to uninstall it.
Hopefully ArcReader will be simpler to use - despite its 205 MB download.
But see also my reply to Mike. Maybe I should simply order a decent paper map and scan and calibrate it with Memory-Map. The learning curve about ESRI shapes, layers etc, etc looks steep!

Duly installed ... but it appears that ArcReader opens only PMF files, not SHP.

BTW, if anyone else has used that GeoBase site I'd be interested to know your views. After persisting for most of the day, I'm finding it virtually unusable. Apart from its rather obscure UI, it's glacially slow at every refresh. I have yet to get a single combination of a target area (say 10 miles square) with all the other elements you expect on a walking map - like clearly identified names of places, rivers, lakes, mountains, etc. And for a fortnight's holiday I need about 13 such maps.
Why don't you just start up Gaggle Earf and draw yourself some lines on top of the area you want? Save your lines as KML/KMZ files and convert them with one of the many utilities to something you can load as map lines or tracks into your gps.

Well GE may indeed be what I end up using. (Although I don't yet have any 'lines' or tracks as I haven't done the walks yet! The rough area will be good enough.) However, a GE-derived map is far inferior to a decent topo map, which is what I'm hoping to find.

You missed the point.
You can draw your own lines in GE - no need to do the walk first - then d/l them to your gps as your map. You just have to see enough of the area you want to walk to be able to make out the roads/trails you want to map. It is not too hard for roads and for hi-res areas, but difficult for lo-res or no roads.
If you want elevations - as in topo maps - why not use ibycus? (I'm sorry - did you already rule this out for some reason?)
If you ever want elevations, just get the 90 meter elevation data from (? can't remember off-hand) and make your own. But of course you need slightly sophisticated software to do this.

No, I think it was you who missed the point! As I said, I don't *know* the actual 13 or 14 paths we will walk during this fortnight. I have a brief brochure description for each, in areas I'm totally unfamiliar with. Here's an example on day 3.
"Banff National Park: Ink Pots ------------------------------ Following Johnston Canyon, beyond the Lower Falls, this trail winds through a forest of lodgepole pine, spruce and Douglas fir. The trail opens up onto Johnston Creek meadows where spring fed pools of striking colour are found. Distance: 11,8km / 7 miles, loop trail with spur at the far end."

A couple of the sites I've found have an elevation layer and GE itself has elevation data too.

Can . . . you . . . see . . . the . . . trails . . . on . . . GE?
If so, you can map them all, and then pick the ones you want to use when you are there.
The point that you missed was that MAYBE you can map them ahead of time from GE - you do not need to walk them first to get the tracks as you mistakenly thought!
But please don't repost anymore just to answer me - I'm done here.
