So I'm trying to make some maps for an upcoming trip down the Ogoki River. One of the maps that I want to print doesn't appear to be copied properly or is a colour topo and is now black and white. Anyway, it is very dark and prints poorly.
This is the site I got the map from - http://ftp.geogratis.gc.ca/pub/nrcan_rn ... k_pdf/042/
the map is 042m01

Does anyone have a suggestion as to where I can print off a better quality map?

thanks
rab

You can try caltopo.com using the "forest service" overlay.

You could try opening in a photo editing software, then convert the colour to bw and liberally mess with the levels, curves whatever is on hand so it prints better. I like staples for colour to colour prints but simple at home bw is good and that can fit the bill. Good luck.

It looks like the features have been drawn directly over the B&W aerial image, not seen than before!

You need to download the TIFF file to open it as a hi-res picture-
http://ftp.geogratis.gc.ca/pub/nrcan_rncan/raster/canmatrix/50k_300dpi/042/m/

I actually don't think it is that bad when you zoom in to a full size image. It is not easy to see the lines but a bit of work with a sharpie or a highlighter would make them easier to see.

You could check out Natural Resources Canada Toporama website for a better map to print -

http://atlas.nrcan.gc.ca/toporama/en/index.html#

Here is the Toporama look of a small section of the 042M01 topo you mentioned -

True North,

Could you give a quick walk through how to get maps from toporama. I can locate the area I want but don't seem to be successful in downloading the map to my computer.

Thanks for the tips folks,
I'll try a couple of them.
I have also been unsuccessful in downloading the maps from toporama

rab and ipaddle - I've never figured out how to download maps from Toporama either! Besides, I am not even sure if Natural Resources Canada is supporting it any more. It is apparently a "legacy product"!

Here is what I have always done if the canmatrix 1:50000 were not the greatest - like the 042M01 that rab asked about -

1. Get the stretch of river that I want in 1:50000 scale on the computer screen.
2. Take a screenshot.
3. Crop boost colour and sharpness if necessary.
4. Print in a size (8"x14") that fits into my map case.
5. Repeat with the next stretch of river.

Admittedly a hack solution. Given that you only need it for a day, it works out fine!

FYI - Quite a bit of the Hudson Bay lowlands (Ontario side) have these Satellite images overlaid with some of the usual topo information.

As I recall the 1:250k maps do not have this issue. For some areas (lower Attawapiskat or Albany) the 250k maps are actually more informative than the 50k versions.

World of Maps here in Ottawa can print you anything you want.

Google them - it is right around the corner from my house about 2 minute walk.

Get the Garmin topo maps with basecamp. I haven't used 1:50's in years.

I'm curious as to how you would print from the Garmin maps.

wotrock, you view your Garmin Topo Canada map in a computer app called Basecamp. Basecamp has a "print" option.

http://www.garmin.com/en-US/shop/downloads/basecamp

Another great thing about Basecamp is that you are able to enter additional data to the maps before you upload it to your Garmin device. Also, you need to check the operating system requirements - both Windows and Mac - to make sure you have the needed OS.

All of this presupposes that you have spent the $100.plus for the Garmin Topo Canada set - or somewhat less for just one of the regions.

https://www.mec.ca/en/product/5009-325/TOPO-Canada-DVD

The Natural Resources Canada map info is free to download or to make an image of.

Related, I'd like a 1:250,000 map printed by a local print shop to prepare for my upcoming Reindeer Lake paddle this summer. I've done this in the past with individual 1:50s and it has worked well. However, this time I want portions of maps 64C, 64D, 64E & 64F combined to make a single overview map.

The way I would be inclined to do it is to download the maps I need from here, choosing the tiff files: http://ftp.geogratis.gc.ca/pub/nrcan_rn ... k_tif/064/
I could then use some sort of image software to match the edges, then crop to the portion that I actually want. The file that results can then be sent to the printer.

BUT, is there a better way? Can I export from Basecamp to produce a decent quality large size paper map? (I do have Basecamp and the Garmin Topo that goes along with it.) Can I somehow just download the portions that I need from and save myself trying to cut and paste images together?

I find lots of other file formats that I can download for my region using this link: http://ftp.geogratis.gc.ca/pub/nrcan_rn ... .html#link
But, I don't know what to do with anything other than the pdf or tiff files.

I'm pretty sure that screenshots are not the way to go in order to get any sort of resolution.

Thanks in advance,
Bryan

Once there click the "Themes" tab and it brings you to the next screen. At that page I chose "Raster", mostly because none of the other options gave me things that I knew what to do with.

I then choose the set that I want (I wanted 1:250k for eventual printing so I took the "Print Ready" version) and zoomed in to the area I want, then clicked on the map that I want. Once I click on the map that I want, it brings up a "Preview and download" page.

I can then choose to download the tif. Giving me a good-enough-to-print version of this that I can crop & print or take to a local large-format print shop. Printing in b&w can be very cheap, by the way. Printing in colour costs a lot more.

I hope this helps.
