DETERMINING YOUR MAP COORDINATES
Your Map Coordinates (number and letter) were first
used in Skywarn operations to quickly identify where
in the county you were reporting. The number and
letter define a 1-mile box, with the number being the
left edge and the letter being the top edge of a box.
Convention has the number given first, followed by the letter. For example, suppose your location was Springport at at the Spring Brook river, at its confluence where it meets with Otter Creek. You would report your position as 4.5C which is grid square 15.
We use a Jackson County Road Map for the coordinates. Any recent road map will do or there is one on the CARS Web Site (Skywarn page) that can be viewed. Caution–these maps are 6-7 Meg file sizes and may take some time to download to your system.
If downloading the map(s), set the Zoom to at least 50 % and use the slider bars to pan around to your area.
A city map of Jackson is also attached for downloading or viewing.
