Those interested in modern digital high-resolution on-line mapping should check out the BC Basemap Viewer. The entire province has been mapped with aerial surveys at 20m data-point spacings; the results are excellent. See: http://maps.gov.bc.ca/imf/imf.jsp?site=bc_basemapThe viewer is quite intuitive; remember to turn "ON" the layers. Turning "OFF" the 3rd "Grids and Images" tab ("TRIM Orthomosaic") removes photo-overlays which interfere with visibility in some areas. 48,000 scale (anything sub-50,000) is good for "cruising", as it includes most point elevations. Zooming "OUT" to 96,000 shows 100m contouring and key placenames. Zooming "IN" shows ever-greater detail. Have fun!

New location for BC basemap viewer: Go to http://maps.gov.bc.ca/Then click open the "Provincial Basemap" hotlink. The operation of the viewer has changed a bit, and is a touch less user-friendly. You need to click the "Layers" tab at the top, then click open the "Base Map Layers" folder, then select the info you want added to the view. The thing is, you generally want EVERYTHING in the "Base Map Layers" section, but because the info is scale-sensitive, you can't access it all until you're in to about 1:100,00 scale or tighter. Hassle... But you can get to "tight" scale quickly by clicking on the map at about the location you want [to save moving a lot afterwards], then (after it reloads) re-entering the scale at (say) 1:96,000 in the box lower left and clicking to "GO" button, and making your complete selections after the re-load finishes. Reminder: keep the 3rd "Grids and Images" tab ("TRIM Orthomosaic") OFF so as to remove photo-overlays which interfere with visibility in some areas. Cheers,

The site has changed again - the "basemap" now has very little detail on it. However the link for "Land and Resource Data Warehouse Catalogue" has all the old stuff. Just go to maps.gov.bc.ca and click on the link, or the direct url is as follows: http://maps.gov.bc.ca/imf406/imf.jsp?site=lrdw_catalog_ext

I'd just like to add that there is a nice server for worldwide sattelite pics down to 1/2" per pixel at http://onearth.jpl.nasa.gov/ I find zooming in on Vancouver Island is fun, but I obviously have a location bias. The Nomash valley is quite prominent and the whole geography of the area becomes quite plain - including the bright green clearcuts. Also, nice pics of Mt Ranier from space.

>Seems very useful for checking out exactly actual existence of > spur roads Well, in areas I happen to know fairly well the roads I hapen to know are there are not really very prominent, but if you *can* see it you are pretty sure it's really there. But the fact that it's faint or nearly invisible doesn't necessarily seem to mean it isn't there and passable, on foot at least. > However, it shows all rock as red And not all that is red is rock. > and is shot from the south for this area, You wanna see something weird, zoom in on Baffin Island.

http://srmwww.gov.bc.ca/g/makeamap.htmlLooks like this is the latest try at providing an official web page for this application.

I may go through with my evil plans to scan in a bunch of topos and stitch them together.
Save yourself the effort, if not some $, and check out Fugawi. C$100 gets you every topo map in the province, and their software (C$150) lets you stitch them together seamlessly. Good for hours of trip plannning fun!

The 1:50,000 maps are notoriously inaccurate. The TRIM data from the BC Basemaps are much more up-to-date/ A website I use to generate BIG maps of areas of interest is trail.brijn.nu. It extracts BC Basemap data and overlays it with GPS UTM grids in NAD83 format. Only problem - no placenames or placenames are very small Some examples of maps I've created are here. I marked up all the placenames myself with Photoshop Elements: http://www.leelau.net/ns.htm

The BC Basemap access has changed significantly.The portal is now through a federal website: http://www.nric.ca/The basemap data is now called "iMap BC". Once you get to the actual basemap, it's mostly the same, but it is harder to find a link to turn the contours on. It took me a couple of minutes to figure out how to do it. You have to add basemap layers because contours are not in the options provided in the layers that are already turned on.

At least for now, the good old basemap is still available with the direct link: http://maps.gov.bc.ca/imf50/imf.jsp?site=bc_basemapThere is another interface at http://openmaps.gov.bc.ca/This is similar to the one G-spotter mentions, but it seems easier to get contours and less clutter. Unfortunately it doesn't seem to want to show contours on glaciated regions.

Save yourself the effort, if not some $, and check out Fugawi. C$100 gets you every topo map in the province, and their software (C$150) lets you stitch them together seamlessly. Good for hours of trip planning fun! In other mapping news, I recently discovered that you can download, for free, any Canadian 1:50k or 1:250k topo from Natural Resources Canada's GeoGratis website. The map images are in TIFF format and include geospatial data. They can be viewed with any imaging software that supports TIFF, or they can be imported into mapping/GPS software packages like OziExplorer or Fugawi. I'm not sure how long this has been available, but it means you no longer need to buy maps from Etopo or Fugawi.
