Geologic hypermaps are more than clickable maps!
Agnès Voisard · 1998
Geologic maps are interpretations of 3-D phenomena. The major aspects to be modeled in such maps are fuzziness (both on assumptions and on geometric components of the geospatial objects they contain) and complex relationships among the underlying data. In addition, map making is an incremental process which asks for multidimensional versioning on spatial components, time and assumptions. Hypermaps are composed of maps, multimedia objects and links among these objects. In this paper we first identify the database features needed to model geologic hypermaps. We then propose a query classification based on data types as well as a model to describe the structure of such maps. 1 Introduction A geologic map provides information regarding the underlying structures of a given area. It contains many different types of information, which makes it complex. It is based on various types of information such as field observations, drill holes and fossil records. From this information the geologist ...
