Abstract
With the advancement in computer technologies, many algorithms have been developed that mimic the human behavior of accurately identifying the objects based on patterns, colors, textures, sizes, shapes. Based on the previous research, Object-Based Image Analysis (OBIA) approach has come out to be an emerging technology that can easily extract the objects like roads, buildings, rivers, lakes etc. from the remotely sensed image. In this paper, mapping of glacier ice/snow and the glacial lake has been performed. As a case study, Siachen glacier situated in the eastern Karakoram Range in the Himalayas has been mapped from Landsat 5 using OBIA approach. The rule base classification has been implemented by using eCognition Developer software.
