“…Despite this there has been some limited success in the use of automated algorithms to map drumlins (e.g. Saha, Wells, & Munro-Stasiuk, 2011). As such, drumlins seem likely to be able to be mapped accurately, reproducibly and objectively, and are regularly interpreted upon this basis, yet making this operational remains a challenge.…”

“…Basicamente, os principais dados na geomorfometria são parâmetros e objetos extraídos de Modelos Digitais de Elevação (MDE), que são utilizados para diferentes propósitos, tais como: classifi cação das Formas de Terreno (FT) (DRAGUT e EISANK, 2011;EHSANI e QUIEL 2008EHSANI et al, 2010;SAHA et al, 2011;VASCONCELOS et al, 2012), delimitação e classifi cação de bacias de drenagem (MENKE et al, 2013;OLIVEIRA et al, 2007;SODRÉ et al, 2007), movimentos de massa GUIMA-RÃES et al, 2009), mapeamento de solos (BARBIERI et al, 2008;CAMARGO et al, 2010;CHAGAS et al, 2013;LEÃO et al, 2011), detecção de fi tofi sionomias (BISPO et al, 2010;CARVALHO JÚNIOR et al, 2008;COUTO JÚNIOR et al, 2010;FONSECA e SILVA JÚNIOR, 2004), entre vários outros propósitos.…”

“…Portanto, o mapeamento das FTs pode subsidiar a escolha de áreas representativas do funcionamento da dinâmica de elementos bióticos e abióticos, adquirindo um papel fundamental para a gestão dos recursos naturais. Com a maior disponibilização de MDE nas últimas décadas e o desenvolvimento de técnicas de análise dos atributos geomorfométricos em Sistemas de Informações Geográfi cas (SIG) houve um avanço signifi cativo na geomorfometria para a classifi cação das FTs (DRAGUT e BLASCHKE, 2006;DRAGUT e EISANK, 2011;EVANS, 2012;IWAHASHI e PIKE, 2007;JASIEWICZ e STEPINSKI, 2013;KLINGSEISEN, et al, 2008;REU et al, 2013;SAHA et al, 2011;VASCONCELOS et al, 2012). A seleção dos atributos geomorfométricos a ser utilizada, normalmente, depende do relevo a ser modelado, do procedimento de classifi cação e do MDE disponível.…”

“…Such methods have also contributed to evolving new software and hardware architectures. For instance in Dollner and Hinrichs (2000), Saha et al (2011), andMcKinney andCai (2002), the objects and terrain are represented as an object-oriented data structure concept and each building is assigned to an object. The properties of the building include roof type, roof polygons, height, roof surface and LIDAR point sequence.…”
