Overview
of Map Algebra |
|

Maps
are a fundamental spatial concept capable of representing and storing large
amounts of information in a visual form. Although maps are an intuitive basis
for geometric applications such as spatial DBMSs
and GIS, these applications do not incorporate maps as a fundamental data
type. Instead geometric data types such as regions are compiled together to
form map representations.. Thus, maps
are not considered "first class citizens" in spatial software systems,
but are mainly for visualization. Operations over maps represented as collections
of regions are difficult to define and implement because each individual
region has no knowledge of structural information inherent in maps.. Thus, the notion of a map algebra, in which
maps are considered fundamental data types, has gained popularity in spatially
oriented fields.. In this talk, I
provide an overview of "map algebra", a formal data model aimed at
supporting map data. |
