Open Government Licence – Vancouver
City of Vancouver open data, including the dedicated fire protection water mains.
Contains information licensed under the Open Government Licence – Vancouver.
Open Government Licence – British Columbia
Provincial records that state it on the record itself. A provincial web address confers no licence.
Contains information licensed under the Open Government Licence – British Columbia.
Every dataset and document behind a figure is listed on the sources page, with the licence stated on it.
Photographs
Each photograph carries its credit on the page where it appears, including the photographer, date, location, collection and licence link.
One of them is licensed for non-commercial use only. This site is free, carries no advertising, no affiliate links and nothing for sale, so the condition is met.
Material linked but not reproduced
Metro Vancouver’s seismic microzonation maps cannot be republished commercially without written approval from the Institute for Catastrophic Loss Reduction. The restriction also covers statements and conclusions drawn from the maps. The ground conditions page links to them.
The maps describe regional ground conditions, not individual properties. A site investigation is needed to assess a specific building.
The provincial hazard tool, the regional Disaster Response Route map and most cited reports state no licence. QuakeImpact reports facts from them with credit and a link, but does not copy or adapt their wording, tables, figures or maps.
The two earthquake videos on the shaking page are embedded from YouTube, not hosted or reproduced here. The rights stay with whoever uploaded them, each card links to the video’s own page, and the embeds use the privacy-enhanced host and do not play by themselves.
