Short answer
Which protection layers should I check?
Check the catalogue’s relevant protection areas for the site being investigated. An intersection is a reason to inspect source evidence, not an automatic approval or prohibition.
What this group contains
Locate the protection layers relevant to the site. Their presence, extent and applicable conditions need source verification; they are not a complete list of restrictions.
- Airport protection
- Cultural heritage buildings
- Cultural heritage monuments
- Heritage protection areas
- River and canal protection
- Gas pipeline protection
- Cemetery sanitary protection
- Lake and wetland protection
- Power-line protection
Read it in Atlas
- Enable the relevant protection layer and read its legend.
- Compare the protection boundary with the parcel, not only its centre point.
- Before applying a condition, check the official record, applicable edition and precise object.
What the layer does not establish
A monument record, heritage building and heritage protection area are distinct layers. Absence from the displayed map does not establish the absence of every possible restriction.
A catalogue entry is not a live availability claim. Coverage, source status and loading errors are shown in Atlas.
