This map of the total magnetic field was derived from data acquired during an aeromagnetic survey carried out by EON Geosciences Inc. during the period between April 12, 2010 to June 2, 2010. The data were recorded using a split-beam cesium vapour magnetometer (sensitivity = 0.005 nT) mounted in the tail boom of a Piper Navajo 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 N45°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 magnetic field.

This map of the total 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.

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 polygon dataset was created to provide a record of the designated Provincial Waterways in Manitoba. This database contains lines and polygons showing the locations of provincial waterways, such as drains, diversions, detention basins, floodways, dams and reservoirs. This dataset was created by digitizing high-resolution imagery of the water features and by digitizing the titled Water Control Work plans associated with the features for drains which have been designated as provincial waterways by Order-in-Council.This dataset was created to provide a record of the designated Provincial Waterways in Manitoba and was intended for use in administering Provincial Waterways Authorizations. Provincial Waterways are designated by Order-in-Council and are under the administration and control of Manitoba Infrastructure (MI) through the Water Resource Administration Act.

This map of the residual total magnetic field was derived from data acquired during an aeromagnetic survey carried out by Goldak Airborne Surveys during the period May 16, 2009 to July 1, 2009. The data were recorded using a split-beam cesium vapour magnetometer mounted in the tail boom of a Piper Navajo aircraft. The nominal traverse and control line spacings were 400 m and 2400 m, respectively, and the aircraft flew at a nominal terrain clearance of 150 m.
