Documents about the project.

This folder contains shapefiles for country outlines and cgrs squares. These can be used in any suitable GIS to prepare an overlay of CGRS squares on the country outline.

A zipped plugin for QGIS to prepare distribution maps was added in September 2020.

The country zip files were updated on 2020-09-18 to include shapefiles in the Europe Lambert Conformal Conic crs (files with LCC in the name)
