Data Source Evaluation

Copy Right Issues
If you are going to use the map for commerical use; you would need written permission from Natural Resource Canada, and the following criteria:
•Users exercise due diligence in ensuring the accuracy of the materials reproduced;


•Natural Resources Canada be identified as the source department; and,

•The reproduction is not represented as an official version of the materials reproduced, nor as having been made, in affiliation with or with the endorsement of Natural Resources Canada.

Differances:
Dates are different from one map to the next and one map has meters and the other is in feet.
Horizontal 125 m/100 m/50 m
Vertical 100 m/20m
The map currency; the land would not change but other things like roads/townsites/natural disasters wold change.
