Gall Isographic Projection
Gall isographic projection is a specific instance of equirectangular projection such that its standard parallels are north and south 45°. The projection is named after James Gall, who presented it in 1855.

Gall Isographic Projection SW
Galls (from the Latin , 'oak-apple') or ''cecidia'' (from the Greek , anything gushing out) are a kind of swelling growth on the external tissues of plants. Plant galls are abnormal outgrowths of plant tissues, similar to benign tumors or warts in animals. They can be caused by various parasites, from viruses, fungi and bacteria, to other plants, insects and mites. Plant galls can be such highly organized structures that their cause can be determined without the actual agent being identified. This applies particularly to insect and mite plant galls. The study of plant galls is known as cecidology. Anatomy Shape and size Galls develop on various plant organs, providing nutrition and shelter to inducing insects. Galls display vast variation in morphology, size, and wall composition. The size of insect galls can range significantly, from approximately two inches in diameter to less than one-sixteenth of an inch. Some galls are so small that they are merely slightly thickene ...

Equirectangular Projection
The equirectangular projection (also called the equidistant cylindrical projection or la carte parallélogrammatique projection), and which includes the special case of the plate carrée projection (also called the geographic projection, lat/lon projection, or plane chart), is a simple map projection attributed to Marinus of Tyre who, Ptolemy claims, invented the projection about AD 100. The projection maps meridian (geography), meridians to vertical straight lines of constant spacing (for meridional intervals of constant spacing), and circle of latitude, circles of latitude to horizontal straight lines of constant spacing (for constant intervals of circle of latitude, parallels). The projection is neither equal-area projection, equal area nor conformal map projection, conformal. Because of the distortions introduced by this projection, it has little use in navigation or cadastral mapping and finds its main use in thematic mapping. In particular, the plate carrée has become a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Gall
James Gall (27 September 1808 – 7 February 1895) was a Scotland, Scottish clergyman who founded the Carrubbers Close Mission. He was also a cartographer, publisher, sculptor, astronomer and author. In cartography he gives his name to three different map projections: Gall stereographic projection, Gall stereographic; Gall isographic projection, Gall isographic; and Gall–Peters projection, Gall orthographic (Gall–Peters projection). Life Gall was born on 27 September 1808, the son of Ann Collie and James Gall, a printer who founded the printing company of Gall & Inglis in Edinburgh, which specialised in easy-access astronomy. His uncle, John Gall, ran a coach-building business. He was baptised at St Cuthbert's Church, Edinburgh on 15 October 1808. He lived with his family at Potterrow on the South Side of Edinburgh. He was educated at the Royal High School, Edinburgh, High School close to his home and at the Trustees Academy. He was then apprenticed as a printer in his ...
