[Gdal-dev] Re: Raster Soviet Topo Maps

[Sylvain Rioux]

Hi Stephen,

Sorry to bother you but we are a reseller of the CanMatrix product and we're
much cheaper. We deliver by download or on cd-rom. The maps are also
collarless (so you can navigate seamlessly on software that allows it).

If you want, just have a look at :

Hi Stephen, thank you for describing the approach you are using.

> Where can you get the Canadian NTS maps from? Are they a free download?

No not free, unfortunately. The product is called CanMatrix and can be
purchased from Natural Resources Canada Centre for Topographic
Information,
http://www.cits.rncan.gc.ca/cit/servlet/CIT/site_id=01&page_id=1-005-002-003
.html

On the bright side, if the resolution is reduced to 150dpi and the image
size does not exceed 16,000,000px there are no restrictions on
redistribution. Anyone who wants the sixty-six 1:250,000 maps which
cover the Yukon Territory can drop me a line (250mb).

Although CanMatrix are 300dpi the quality in my opinion is not so hot. A
test scan here in our office at the same resolution yielded much better
results. However, they've already done it, the images are georeferenced,
and our scanner bed is not big enough. :)
