libgeography-nationalgrid-perl | Class for a point and to transform coordinate systems | Mehr ...
You ask for an object for the correct country, described using the ISO 2-letter country code. You will need to supply information to the constructor. You may then call methods on that object to do whatever operations you need. Conceptually each object represents a point on the ground, although you some grid systems may take that point to be a corner of a defined area. E.g. a 6-figure OS National Grid reference may be thought of as the point at the south-west of a 100m by 100m square. . This package also includes the extra module Geography::NationalGrid::TW.
