I need to make a map on map composer, with a grid layed on it which is 500m x 500m. however the only way I could find of doing this was by adding a grid to my map, found within item properties.
This works fine however to get a grid of 500m, I have had to set the 'Interval' to
x = 0.009200000000 Y = 0.009200000000
with the 'Interval units' set ot 'Map units' which in this case is 'Meters'.
Is there an accurate way to produce a grid to fit a required distance accuratly?.
I am usign QGIS V3.4
