This study detected the spatial changes in Snow Cover Area (SCA) over Snowy Mountains New South Wales, Australia. We applied a combination of Object-Based Image Analysis (OBIA) algorithms by segmentation, classification, and thresholding rules to extract snow, water, vegetation, non-vegetation land covers. For validation, Maximum Depths (MSDs) were collected at three local snow observation site...

abstract in the recent decades, application of geostatistic and remote sensing for mapping salinity and sodicity of surface soil and monitoring it's changes have been developed. the goal of this research was to compare the capability of geostatistic and remote sensing methods for mapping salinity-sodicity of soils in playa from sourthern mah valat county, in the khorasan razavi province. 88 sam...

Abstract The Valley of the Kings (KV) is a UNESCO world heritage site with more than thirty opened tombs. Since first tombs were constructed, at least 24 historical flash flood events has been identified, each which contributed to destruction and deterioration Recently, most these have damaged inundated after 1994 flood. In order understand Geo-environmental impact mainly past floods due intens...

Soil salinity / alkalinity development is one of the major land degradation problem affecting sustainable agricultural productivity in irrigated areas of arid and semi arid regions of the world. The characterization and mapping of salt affected soils is difficult as the salt concentration may vary substantially over short distances. Various broadband multi-spectral satellite data and spectral i...

salinity and sodicity are the major factors of soil degradation in arid and semiarid areas. the main aim of this study was to evaluate the capability of liss_iii data for soil salinity and sodicity mapping in a selected part of the qazvin plain, an area of arid environment. during the study, spectral classes were carried out of the remotely sensed data and then with the help of field observatio...

The disappearance of some glaciers of the world is due to the global climatic heating and other correlated phenomena. This also endangers the other glaciers, providing many repercussions on the availability of natural water resources for agricultural, civil and industrial purposes. This research developed a study process to analyse the status of some Alpine glacier groups (Adamello, Ortles-Ceve...
