Web Cartography

CartographyCartography is the art and science of expressing the known physical features of the earth graphical by maps and charts.

MapsMaps are made for many reasons, and as a result, vary in content. Some maps made for general purposes may show roads, towns and cities, rivers and lakes, parks, and State and local boundaries. The history of civilization has been illustrated by maps: battle maps by soldiers, exploration maps by empire builders, thematic maps by scientists.

HistoryNo one knows who drew, molded, laced together, or scratched out in the dirt the first map. A study of history reveals that the most pressing demands for accuracy and detail in mapping have come as a result of military needs.

Early MapsThe earliest atlases in the Library of Congress are associated with Claudius Ptolemy, an Alexandrian scholar who recorded and systematized classical Greek geographical knowledge during the second century. He titled his cartographic publication as the Geographia.
