RESUMO

Most implementations of Geographical Information Systems (GIS)include procedures, which allow the user to express complex spatial analysis models. These procedures are refereed to as Map Algebra, and are usually expressed by a language, which provides operations that generate new maps from an existing ones. The GIS system developed by National Institute of Space Research (INPE), includes the a spatial algebra language, whose use requires notions of programming languages. Such knowledge is not always available in the GIS user community. As an alternative to direct programming using this programming language, we have developed a friendly user interface for expressing Map Algebra programs, called (AMO)that means Map Algebra with Objects. AMO uses the flow diagram paradigm, which is a natural way of expressing spatial analysis problems, and enables the automatic generation of Map Algebra programs. In order to develop AMO, we have analyzed different alternatives for Map Algebra interfaces, including programming languages, forms and flow diagrams. AMO is an improvement of INPEïs GIS technology, as it allows non-expert users a straightforward way of expressing complex spatial analysis problem. Finally, the AMO design has been based on general principles of GIS, and the interface can be extended for use with other systems.
