AbstractThis work presents a proposal for an algebra of geographical fields. Geographical fields are the mathematical expression of continuously-varying spatial data, such as thematic maps, digital terrain models and satellite imagery. The paper outlines an initial proposal for an algebra of geographical fields that enables the definition of operations based on the properties of geographical data, independent of their graphical representation. This proposal is being used as a data manipulation language in SPRING, a geographical information system developed by INPE.
