The development of UAV technologies offers practical methods to create landcover maps for monitoring and management areas affected by natural disasters such as landslides. present study aims at comparing the capability two different types deliver precise information, in order characterize vegetation landslide over a period months. For comparison, an RGB Multispectral were used identify three classes: vegetation, bare soil, dead matter, from April July 2021. results showed high overall...
The number of intense tropical cyclones is expected to increase in the future, causing severe damage forest ecosystems. Remote sensing plays an important role detecting changes land cover caused by these storms. techniques have been widely used different phases disaster risk management because they can deliver information rapidly concerned parties. Although remote technology already available, examination appropriate methods based on type still missing. Our goal compare suitability three...
Summary Degradation of floodplains continues with an increasing number floodplain lakes disconnected from the fluvial dynamics rivers. Limited understanding is available as to how historical geomorphic formation processes (i.e. legacy) determine contemporary ecosystem structure and function. We tested hypothesis that legacy mediates morphometry results in heterogeneity macrophyte distributions lakes. The distribution cover was examined relation environmental factors, including water nutrient...
Disturbances in forest ecosystems are expected to increase by the end of twenty-first century. An understanding these disturbed areas is critical defining management measures improve resilience. While some studies emphasize importance quick salvage logging, others deadwood for biodiversity. Unmanned aerial vehicle (UAV) remote sensing playing an important role acquire information through structure-from-motion (SfM) photogrammetry process. However, technique faces challenges due fundamental...
Understanding the skier's behavior (including snowboarders and other equipment users) in a snow area contributes not only to efficient management of safety facilities but also improving services. However, manager knows number skiers who use lifts or gondolas general. We proposed framework analyze with GPS resorts, which consists two standpoints such as inter- inner-ski slopes. clarified both transition choice relation ski slopes, lifts/gondolas rest places (inter-ski slopes), movement each...
