Concepts of Maps,ms; in other words, we propose a fundamental data type of maps and a set of associated operations that together form a .. We explore the notion of maps in a variety of settings in order to illustrate the fundamental properties of maps, and then show how our proposal of the Map Framework addresses the needs and properties of maps in those settings.

A Formal Model of Maps as a Fundamental Type,This chapter reviews the algebra defining the traditional spatial types, their operations, and topological predicates. This algebra forms the foundation of spatial data processing using vector data and is also used as the foundation for the Map Framework. Finally, the formal model of maps is developed.

PLR Partitions: Extending Maps to Include Point and Line Features,Spatial partitions represent maps containing areal features and their boundaries. In this chapter, we extend the definition of spatial partitions in to PLR partitions (Point, Line, Region Partitions) which represent maps containing point, line, and region features.

Constructing Map Operations Using the Fundamental Map Operations,A powerful aspect of the Map Framework is that the power operations are able to be composed to form complex operations over maps. In this chapter, we identify common map operations from the literature, and then derive them in the context of the Map Framework.
