Locator squares for IOW
Maidenhead Locators for the Isle of Wight
IO90xx
These squares are based on Latitude/Longitude.
Below the vertical Longitude lines are 0.050° apart. The left border of my square, IO90IR is at 1.200°W
The horizontal Latitude lines are 0.025° apart. The top border of my square, IO90IR is at 50.450°N
This is based on OSGB 10Km squares that are NOT directly based on Lat/Longitude.
It is best to refer to an Ordnance Survey map. There are conversion programs, but MAY not be absolutely precise. A suitably configured GPS will give an accurate position. But has to be one that can be configured to show OSGB coordinates.
