Yujitu (Map of the Tracks of Yu), 1136 (Raster Image)

This layer is a georeferenced image of a 1136 map titled 'Yujitu' (Map of the Tracks of Yu). This map's title derives from the Yugong, a treatise describing the sage-king Yu's mythical channeling of China's rivers. It is a rare surviving example of cartography used in the 12th century for public education, mixing classical references with later administrative history. Carved on a large stone tablet so that students or visitors could make rubbings, the map strikingly depicts a riverine network on a regular grid of squares intended to represent 100 li to a side. The historic map layers in the Google Earth Rumsey Map Collection have been selected by David Rumsey from his large collection of historical maps, as well as some from other collections with which he collaborates. All the maps contain rich information about the past and represent a sampling of time periods, scales, and cartographic art, resulting in visual history stories that only old maps can tell. Each map has been georeferenced by Rumsey, thus creating unique digital map images that allow the old maps to appear in their correct places on the modern globe. Some of the maps fit perfectly in their modern spaces, while othersgenerally earlier period mapsreveal interesting geographical misconceptions of their time. Cultural features on the maps can be compared to the modern satellite views using the slider bars to adjust transparency. The result is an exploration of time as well as space, a marriage of historic cartographic masterpieces with innovative contemporary software tools.
