Build geometrically uniforme partitions and starting these we define generalized coset codes. We generalize the concept of geometrically uniform codes to hyperbolic spaces. We show a characterization of generalized coset codes through the concept of G-linear codes. / Nesta dissertação definimos códigos geometricamente uniformes em espaços euclideanos, apresentando algumas propriedades simétricas destes códigos. Construímos partições geometricamente uniformes e a partir destas definimos classes laterais de códigos generalizadas. Estendemos aos espaços hiperbólicos o conceito de códigos geometricamente uniformes. Mostramos também uma caracterização de classes laterais generalizadas através do conceito de códigos G-lineares.
