Topographic charts, land survey plans, and technical drawings degrade quickly without proper storage. This resource covers practical methods for archiving these documents under Canadian climate conditions.
Recommended relative humidity for paper map storage
Stable temperature range for long-term archiving
Materials standard for permanent document preservation
Key Topics
Three areas where improper storage causes the most damage to paper cartographic documents in Canadian homes.
Topographic maps stored rolled over time develop permanent creases and edge tears. Flat storage in shallow drawers prevents mechanical damage while allowing easy retrieval.
Canadian winters bring low indoor humidity that causes paper to become brittle. Canadian summers introduce moisture that promotes mould. Stable conditions require active management.
Standard cardboard folders and envelopes off-gas acids that discolour and weaken paper over years. Acid-free enclosures slow this process significantly.
