Can't guarantee how long these links will work. I highly recommend subscribing to Caltopo. Well worth the $20.


Even the unpaid version is back to being great. There was a period (within the timelines of this thread) where the NRcan maps disappeared from Caltopo. During that time they had the USGS maps but they only covered up to 50 degrees north. Now they have them all back but they are found in the "scanned 7.5'" layer instead of a specific NRC layer as they were before.

I am looking for a source of free topo maps of canada 1:50,000. I used georgratis until recently but now it's not downloading. Can you recommend another source? I can make a shot of the screen so downloading feature is not necessary but I do need to see the gridlines and co-ordinates.

I can still view/download through this site:

http://ftp.geogratis.gc.ca/pub/nrcan_rn ... pographic/

Can't go anywhere, but I can look at the maps.

I usually find the link jmc posted by starting here

I've considered downloading the whole kaboodle, before they all go offline. I can't yet figure out how to make any use of the CanVec maps.

Maybe Caltopo will give you what you want?

You can create maps with grid lines in Caltopo.

This example uses an older (1979) raster Canmatrix map layer. The doubling up of UTM lines is because of changes since the original raster maps were printed.

Or you can use the NR Canada layer. No doubling up of grid lines but you lose some of the great detail from the older maps.

Martin, are you still using Google Earth similarly to your original post?

My maps are pretty much exclusively Caltopo anymore. I still use Google Earth for poking around, measuring distances, adding paths and way points. But I then add these into Caltopo for print or GeoPDF files.

Same here, pretty much all the map stuff on Caltopo since they solved the issues they had when the https protocol was implemented.

For poking around I've been using zoom.earth more than Google as they offer a variety of Satellite views, "real-time", daily and older Google layers to choose from.

I have not peeked at Zoom in a while---will lookagain.Note that GE also has older pix under "Historical Imagery"

WRT poking around in satellite views, Google Earth's sat photo resolution has improved to the point where individual human figures can be resolved in some places... parking lots and sidewalks in Toronto for instance. Previously Ontario top maps had the finer resolution, GE's is now a little bit sharper, at least in the places I've spent time checking out. It's best to use both and any other sat photos wherever you can find them since Google Earth might include winter views photographed from up there in outer space and those are harder to interpret with snow and ice making the landscape look different.

Thanks! Hadn't heard of that one. This site offers multiple imagery layers too https://satellites.pro/

The older top maps also had features marked that the new top maps don't include... this map I bought during the eighties sometime shows the locations of old logging roads... below is a photo of an area in APP with old roads I've walked, one leading to the abandoned 1860s Booth farm depot next to Farm lake. These have disappeared from the newer maps in the Ontario top maps website above.

https://live.staticflickr.com/2837/3327 ... c4bd_o.jpg

The older maps showing these old roads used to be included in the Gmap4 website but it was forced to close for some reason. I'd love to find out where the older top map archives are with year of publication included. Recped provided a link to top map archives previously but I couldn't find any easily identifiable way to find the older ones (ran out of time searching and haven't returned).

The old Gmap4 link:
