Help – UAV site selection tool

The latitude and longitude coordinates of the mouse pointer are shown in the control bar along the left side of the map pane. From the control bar, you can also find a particular area of interest by zooming into your location or submitting the latitude and longitude of your preferred search area. You can also type the location name into the search bar in the upper left of the map window. This will re-center the map on the area of interest. Standard Google Maps zoom controls are available on the top right of the map window.

The map will display all known non-Class-G airspace below 300 feet above ground level (AGL) with a red-filled polygon surrounded by a yellow line, and will display a red-filled circle with a red line around the locations of aerodromes listed in the Canada Flight Supplement or Water Aerodrome Supplement. Aerodromes and Heliports found only in other sources are identified with yellow fill. Hovering the mouse cursor over an aerodrome polygon will pop up an information box that indicates the name of the aerodrome. For further information about the aerodrome (including data source, runways, and contact information where available) click on the polygon. At high levels of zoom, markers will appear to identify whether an aerodrome is an airport, heliport, or water aerodrome. Additional information is displayed by clicking on the markers.

Distance limits from the pilot position, and to built-up areas are dependent on the weight of the UAV. Use the radio buttons to select the unmanned aerial vehicle (UAV) weight class for your operation.

To assist operators in determining if their operation complies with distance to built-up areas, clicking on the map will draw a green circle centered at the selected map point. The location of the green circle may be moved by either clicking on a new location outside the green circle, or clicking and dragging the circle to a new location. To determine if the operation is in compliance with the distance from built-up areas requirement, it is recommended to put the map into 'satellite imagery' mode via the controls at the top right of the map window, and then adjust the transparency of the polygon fill such that it is possible to see if there are built up areas (i.e. houses, dwellings, etc.) within the green radius. Ensure that all the bounds of the proposed UAV operation meet this requirement (i.e. don't limit your search to just the center of the operation or the location of the ground control station). Additionally, a red ring is drawn centered at the selected map point. This ring represents the maximum horizontal distance at which the UAV may be operated under the exemption (1/4 nautical mile, or ½ nautical mile depending on weight class).
