RESUMO

Recently, researchers in GIScience argued about the benefits on using functional programming for geospatial application development and prototyping of novel ideas. However, developing an entire GIS in a functional language is not feasible. Support for spatial databases requires a large set of I/O operations, which are cumbersome to implement in functional languages. This thesis presents an application that interfaces a functional language with a spatial database. It enables developing GIS applications development in a functional language, while handling data in a spatial database. We used this application to develop a Map Algebra, which shows the benefits on using this paradigm in GIScience. Our work shows there are many gains in using a functional language, especially Haskell, to write concise and expressive GIS applications. Combining Haskell and TerraLib enables the use of functional programming to reallife GIS problems, and is a contribution to make Haskell a more widely used tool for GIS application development.
