This list provides an overview of some of the significant or common map projections because 1850, practically unused in cartography because of severe polar distortion, but popular in panoramic photography, especially for architectural. A polar projection map shows only the arctic and antarctic areas this map will only show 10 to 15 degrees from either the north or south.
