Reprocessing of magnetic data for Yukon was performed between November 2016 and March 2017. Aeromagnetic data were compiled, data of different resolutions were merged, and a series of images individually levelled for each map sheet were produced. For each 250k-scale map, the following magnetic derivative maps were produced: 1. Residual Total Magnetic Field; 2. Reduced-to-Pole Magnetic Field (RTP); 3. First Vertical Derivative of the Reduced-to-Pole Magnetic Field (RTP_VD); and 4. Tilt Derivative of the Reduced-to-Pole Magnetic Field (RTP_TDR). These maps are provided as pdfs, geotiffs and Geosoft grid files. Colour ramps/legends are provided for each map.

Ascophyllum nodosum, locally known as rockweed, is harvested in the Bay of Fundy and is managed by limiting harvest within sectors and through area closures. Closed areas are closed year-round and include: exclusion areas for management, research, conservation, transportation or security purposes; study sites that are set aside for study purposes; and long-term reference areas that are control sites for potential experiments linked to rockweed and its associated biota. Special rockweed management areas have a delayed opening (July 1st) to conserve seabird populations and avoid harvesting during their breeding season. Only the sectors southwest of the Saint John Harbour are actively harvested.

This aeromagnetic survey was carried out by Geo Data Solutions GDS Inc. from January 12, 2018 to March 16, 2018. The data were recorded using split-beam cesium vapour magnetometers mounted in the tail booms of a Beechcraft King Air and a Piper Navajo. The nominal traverse and control line spacings were 400 m and 2400 m, and the aircraft flew at a nominal terrain clearance of 150 m. Travers lines were oriented N45°E with orthogonal control lines.

BLKPASSAGE_OFFICIAL is one of the important layers for Saskatchewan Upgraded Road Network (SURN) and National Road Network (NRN). The BLKPASSAGE_OFFICIAL provides the information of road blocked passage to clients that require accurate, relatively up-to-date and detailed description of Saskatchewan Road Network. BLKPASSAGE_OFFICIAL, This layer contains data for a structure indicating a physical barrier on a Road Element built to prevent or control further access. BLKPASSAGE_OFFICIAL contains all the blocked passage points in the Saskatchewan. BLKPASSAGE_OFFICIAL is an important part of the Saskatchewan road network dataset. Each point geometry " BLKPASSAGE" has unique Identifiers (NID). "NID" National Identifier is used to manage the updates between data producer and data users.
