[Open-data-census] Better definition of National Map

[James McKinney]

Tracey: geogratis.ca (the link you put for national map) has tons of datasets, many of which are not national maps. A more specific link would be more suitable for "national map".

Andrew: I am not the designer of this census. The "use case" brainstorm you propose is something that I would assume the designers have already accomplished. My email asks the designers for more clarity than they currently provide.

My questions remain open (and are not specific to Canada's case) and I would still appreciate direction from the people who designed the questionnaire.

Thanks,

James

It might be worth describing typical use cases for electoral and finances – and for maps too, even though the Canada case is solved.
