چکیده
India has made tremendous progress in the aerospace technology in the last two decades. We are one, among the worlds best in satellite and the remote sensing technology. We are also one of the developing countries facing the natural disasters and trying level best to mitigate their ill effects. At the best we can minimize their effect. To achieve this, we need to have a comprehensive management program dealing with mapping and monitoring. The remote sensing technology with the fieldwork provides an edge to characterize the geomorphologic aspects. The present paper reviews the application of the remote sensing tools in the application of geomorphology. A few case studies from the different part of the country are presented in the context of geomorphology of the foothills of Siwaliks, Central India and the eastern coast and use of remote sensing. Resumen: En las últimas dos décadas la India ha hecho un enorme progreso en la tecnología aeroespacial. Estamos entre los mejores en tecnología satelital y de percepción remota a nivel mundial. También somos uno de los países en vías de desarrollo que enfrentan desastres naturales y que intentan amortiguar sus efectos negativos. En el mejor de los casos podemos minimizar su efecto. Para conseguirlo, necesitamos contar con un programa de manejo de gran alcance relacionado con la elaboración de mapas y el monitoreo. La tecnología de percepción remota, en combinación con el trabajo de campo, ofrece ventajas en la caracterización de los aspectos geomorfológicos. El presente artículo revisa la aplicación de las herramientas de percepción remota a la geomorfología. Se presentan algunos estudios de caso de diferentes partes del país en el contexto de la geomorfología de las estribaciones de sierra en Siwaliks, India central y la costa oriental, y del uso de la percepción remota. Resumo: A Índia fez um enorme progresso na tecnologia espacial nas últimas duas décadas. Ela situa-se entre as melhores na tecnologia de satélite e detecção remota. Ela é, também, um dos países em desenvolvimento que enfrentam desastres naturais e fazendo o seu melhor para mitigar as suas consequências negativas. No melhor dos casos ela pode minimizar os seus efeitos. Para atingir este nível, é necessário dispor-se de um programa integrado de gestão que integre o mapeamento e a monitorização. A tecnologia de detecção remota, associada ao trabalho de campo, proporciona um avanço na caracterização dos aspectos geomorfológicos. Este artigo revê a aplicação dos instrumentos de detecção remota na geomorfologia. Alguns estudos de casos do uso da detecção remota são apresentados em diferentes regiões do país no contexto da geomorfologia da base das colinas de Siwaliks, Índia Central e na Costa Oriental.
