Uniquely identifies a 75 metre wide road tenure. This layer uses the centre line from the application and is buffered 37.5 metres either side. This layer does not represent the actual road on the ground. It represents where the application area is

The Landmark Kilometre Inventory spatial layer is used primarily by the Ministry of Transportation and Infrastructure (MOT) to represent routes against which accident data and traffic counts are collected. This method describes roads by a four number designation referred to as a segment (i.e. 0375) This spatial layer was created based on Digital Road Atlas (DRA) centerline using linear referencing

Road centre-lines associated with oil and gas road activity and falling within the area representing the road right of way. This dataset contains line features for approved road centre-line locations collected on or after October 30, 2006. This dataset is updated nightly.

The Single Line Hydrography Network (SLNET) contains all captured single line representations of hydrographic features. In addition, single line representations of polygonal features and single line arbitrary network connectors are in the file.

Phytoplankton pigments, determined by high-performance liquid chromatography (HPLC) are measured on DFO cruises three times a year in February, June, and August/September along Line P in the northeast subarctic Pacific. Sampling for phytoplankton pigments started in 2006 at the five main Line P stations and was expanded to sample at all twenty seven stations along the transect in June 2010.
