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.

This aeromagnetic survey was carried out by Goldak Airborne Surveys from February 17, 2014 to March 21, 2014. The data were collected using split-beam cesium vapour magnetometers mounted in each of the tail booms of 2 Piper Navajo aircraft. Nominal traverse and control line spacings were 400 and 1400 m, and the nominal terrain clearance was 125 m.

This feature class represents Manitoba's Forest Management Licence (FML) boundaries. The Forest Act provides for the establishment of Forest Management Licences to provide a continuous supply of timber to the forest industry. A Forest Management Licence, granted for a period of not more than twenty years, may be renewed for further periods. The Forest Management Licence describes the land upon which trees may be cut, the volume of wood that may be harvested, and other terms and conditions. There are currently two Forest Management Licences in Manitoba, FML-2 and FML-3 . Timber management and forest renewal are the responsibilities of Manitoba Sustainable Government on Crown Forest Land outside of Forest Management Licence areas, and within Forest Management Licence areas where the wood is used by a facility other than that operated by the Forest Management Licensee. Version 3 of Manitoba's Forest Management Licence (FML) boundaries includes FML-2 and FML-3. Previous boundaries associated with FML-1 and IWSA's have been removed. To update and improve the positional accuracy of Manitoba's Forest Management Licence (FML) boundaries, written descriptions of FML areas were referenced along with linework from Forest Land Inventories (FLI), Forest Resource Inventories (FRI) and Manitoba's township fabric to improve Provincial FML boundaries. Boundary linework the following related geospatial datasets were topologically checked for coincident linework: Manitoba Provincial Boundary; Manitoba Forest Management Units ; Manitoba Forest Management Licence Agreement Areas; Manitoba Forest Sections; Manitoba Provincial Forests . Fields Included: FML_NAME : Forest Management Licence area name.

This aeromagnetic survey was carried out by Novatem Inc. from February 23, 2019 to April 2, 2019. The data were recorded using split-beam cesium vapour magnetometers mounted in the tail booms of two Piper Navajo aircraft. 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. Traverse lines were oriented N45°E with orthogonal control lines.

This map of the first vertical derivative of the magnetic field was derived from data acquired during an aeromagnetic survey carried out by EON Geosciences Inc. in the period between April 10, 2009 and September 16, 2009. The data were recorded using split-beam cesium vapour magnetometers (sensitivity = 0.005 nT) mounted in each of the tail booms of a Piper Navajo and a Cessna 206 aircraft. The nominal traverse and control line spacings were, respectively, 800 m and 2 400 m, and the aircraft flew at a nominal terrain clearance of 250 m. Traverse lines were oriented N90°E with orthogonal control lines. The flight path was recovered following post-flight differential corrections to the raw Global Positioning System data and inspection of ground images recorded by a vertically-mounted video camera. The survey was flown on a pre-determined flight surface to minimize differences in magnetic values at the intersections of control and traverse lines. These differences were computer-analysed to obtain a mutually levelled set of flight-line magnetic data. The levelled values were then interpolated to a 200 m grid. The International Geomagnetic Reference Field (IGRF) was not removed from the total magnetic field.
