GEOGRAPHY AND THE PROPERTIES OF SURFACES. SOME THOUGHTS ON OPTIMAL MAPPING AND CODING OF SURFACES.

摘要

Geographers have spent a large part of their time and effort to refine techniques of presenting surfaces of different kinds. Manually produced maps were the usual device. This kind of preparation was appropriate for most purposes as long as the number of maps demanded did not surpass the abilities of the total number of cartographers and draftsmen. In many cases manual preparation is no longer possible. Applicable spatial data are now available to an extent which surpasses all imaginable bounds. This demands new methods of automated data handling,typically separating the process of storage and retrieval of data. This paper will discuss certain points which apparently were not considered in previous studies of systems for automated storage and retrieval of spatial data. (Author)
