Sources

Every dataset behind the map, with its publisher, licence statement, portal link, retrieval date and record count. 11 datasets feed the layers on the map in build 20260917T011556Z; the rest were inspected or are planned and are listed so the decision is visible.

Estimates and their basis

Every value on a record is one of three things: from the cited source, an estimate, or absent ("Not in source"). Estimates carry an amber Estimate badge; hovering it shows the basis. Useful life comes from Statistics Canada, Canada's Core Public Infrastructure Survey (average expected useful life of new assets, 2016 reference, pipes 2020), loaded from config/lifecycle_defaults.json. Replacement values multiply a measured quantity (length, deck area, lane-kilometres) by an InterAsset unit cost that is flagged unconfirmed until reviewed. Remaining life and replacement year follow from the in-service year and the useful life. No public asset receives an invented condition rating, inspection date, cost or work order.
