Methods
(static) getLowerResGrs(gr) → {object}
Given a grid reference (British National Grid, Irish Grid, UTM zone 30N shorthand),
return an object with a corresponsing GR for each precision. For all precisions higher
than the precision of the passed in GR, the return GR is set to null. In the special
returned Quadrant (5 km) grid references are in an array to allow for the case where
the input grid reference is a tetrad and overlaps more than one quadrant.
Parameters:
| Name | Type | Description |
|---|---|---|
