Time Variant Change Analysis in Satellite Images

This paper describes the time variant changes in satellite images using Self Organizing Feature Map (SOFM) technique associated with Artificial Neural Network. In this paper, we take a satellite image and find the time variant changes using above technique with the help of MATLAB. This paper reviews remotely sensed data analysis with neural networks. First, we present an overview of the main co...

Automated Procedures for Integration of Satellite Images and Map Data for Change Detection: the Archangel Project

The need for automation in the registration of image to image and image to map is widely recognised and work has been going on for some time in both the photogrammetric and remote sensing disciplines. For large scale aerial photography the automation of absolute orientation is tied in with feature recognition but for satellite data operations can take place at a lower level and the problem of r...

Analysis of Glacier Mass Balance and Rheology at Kekesayi Glacier Using Hexagon Kh-9, Alos-prism and Sar Data

Scanned stereoscopic spying photography of a Hexagon KH-9 mission in 1973 as well as high resolution stereo imagery of ALOS-PRISM from 2009 was used to generate multi-temporal Digital Terrain Models for the estimation of glacier thickness changes of Kekesayi glacier situated at the Mustag Ata massif at the northwestern end of the Tibetan Plateau. Glacier surface velocities were estimated by amp...

Has climate change driven spatio-temporal changes of cropland in northern China since the 1970s?

Improving the understanding of cropland change and its driving factors is a current focus for policy decision-makers in China. The datasets of cropland and cropland changes from the 1970s to the 2000s were used to explore whether climate change has produced spatiotemporal changes to cropland in northern China since the 1970s. Two representative indicators of heat and water resources, which are ...
