Land degradation by soil erosion and landslides has been recognised as a constraint for sustainable land-use in Eastern Bhutan for a few decades. However, the extreme diversity in agro-ecological zones, the relative inaccessibility of the region, the lack of reliable data and the limited research capacity made it very difficult to develop a relevant land management strategy. To address this iss...

Two photographic missions per year are recommended to provide information on land-use and mosquito oviposition habitats. A winter mission, following a rain, will-provide a view of low areas within fields which may be obscured by summer vegetation. A summer mission will provide current land-use and crop distribution information and may show plant stress conditions due to excessive soil moisture....

This study aims to investigate the characteristics of LIDAR intensity data for executing land cover classification. The quantitative and qualitative analysis was executed with reflection geometry model and land cover classification data. By these analyses, the LIDAR intensity feasibility for classification was discussed. The survey found that intensity is inversely proportional to angle and dis...

Landslides are amongst the most damaging natural hazards in the mountainous terrain like Himalaya. The study of landslides has drawn worldwide attention mainly due to increasing awareness of socio-economic impacts of landslides. Remote sensing images provide many useful land use information to combine in a GIS environment with other spatial factors influencing the occurrence of landslide. The l...

As a common space, urban entrance is the first place that introduces a city to its visitors and it is imprinted in the memory of people. This study aims to provide a detailed analysis of physical development and activity patterns along the main entrance of Rasht, Iran. Utilized data in this research comes from a questionnaire survey through which 707 land lots along the main entrances were stu...

Because conventional Boolean retrieval of soil survey data and logical models for assessing land suitability treat both spatial units and attribute value ranges as exactly specifiable quantities, they ignore the continuous nature of soil and landscape variation and uncertainties in measurement which can result in the misclassification of sites that just fail to match strictly defined requiremen...
