Frequently Asked Questions
What is an element?
An element is a unit of natural
biodiversity : a
species,
natural community
or
animal assemblage.
What is the precision level of
cartographic data?
Three precisions levels are associated
with the
element occurrences presented in the Centre de
données sur le patrimoine naturel du Québec (CDPNQ)
information system, based on observation siting quality:
- precision level “S” (to-the-second precision). Its map siting is accurate to +/- 150 m;
- precision level “M” (to-the-minute precision). Its map siting is accurate to +/- 1.5 km;
- precision level “G” (general precision). Its map siting is accurate to +/- 8 km.
The precision level indicates the area in which the element occurrence in question is theoretically likely to be found. For instance, at precision level “M”, the occurrence could be found anywhere within a radius of 1.5 km.
How often is data updated?
The Centre de données sur le patrimoine
naturel du Québec (CDPNQ) information system is constantly
evolving. New data is added each week and existing data
corrected or completed as we gather new knowledge.
