                         LEGAL, the map algebra language module of the GIS Spring, 
                         resulting from a conceptual revision in which concepts such as 
                         local, zone and neighborhood were unified into the region concept, 
                         with implications in all classes of operations. Besides 
                         incorporating neighborhood operations functionalities, the 
                         language can now explore differences in resolution among data in 
                         more explicit and formal ways, thus allowing operations such as 
                         generalization and aggregation, typical in multi-scale and 
                         multi-resolution data analysis, to be naturally incorporated to 
                         map algebra jargon. We also illustrate the discussion with some 
                         applications aimed to noise removal from classified image and 
                         target detection taking deforestation patterns as target from 
                         images.",
