6. Long Island Digitized: Twentieth-Century Maps

The twentieth century has seen radical changes in cartography. Thematic maps (maps about a subject) have been widely used in this century. Conventional maps have been supplemented by aerial photographs and satellite images. Most maps are now produced using computers, and increasingly maps are being viewed on computer screens. The number of Long Island maps available on the Internet is growing exposively.
