The image is of a flag meant to represent the Earth. The flag has an overall dimensional ratio of width: three, and length: five. It consists of a field of white (HTML color #FFFFFF), in the center of which is a circular ideographic symbol for the Earth as the flag's charge. The ideogram depicts a stylized cartographic projection (Nicolosi globular) and is rendered in white lines (HTML color #FFFFFF) with the spaces among the lines colored blue (HTML color #0000FF). The diameter of the charge is 2/5 of the flag's total length. The thickness of the charge's lines is 1/20 of its diameter. The image was created using Inkscape.
