Abstract:
Snow represents an important resource in mountainous regions. Monitoring its extent and amount is relevant for several applications, such as hydrology, ecology, avalanche monitoring, or hydropower production. However, a correct understanding of the high spatial and temporal variability of snow accumulation, redistribution and ablation processes requires its monitoring in a spatialized and detailed way. Recently, the launch of the Sentinel missions has opened the doors to new approaches that mainly exploit high resolution (HR) data having a spatial detail of few dozens of m. In this thesis, we

Dramatic land-cover changes have occurred in a broad range of spatial and temporal scales over the last decades. Satellite remote sensing, which can observe the earth's surface in a consistent manner, has been playing an important role in monitoring and evaluating land-cover changes. Meanwhile, optical remote sensing, a common approach to acquiring land-cover information, is limited by weather conditions and thus is greatly constrained in areas with frequent cloud cover and rainfall.

Every year wildfires threaten or destroy ecological habitats, man-made infrastructure and people’s lives. Additionally millions of dollars are spent each year trying to prevent and control these fires.

Traditional manned fire lookout towers are neither cost effective nor particularly efficient at detecting wildfire. It is proposed that temporal filtering can be used to isolate the signals created at the beginnings of potential wildfires. Temporal filtering can remove a

Many applications use multiple cameras to simultaneously capture imagery of a scene from different vantage points on a rigid, moving camera system over time. Multiple cameras often provide unique viewing angles but also additional levels of detail of a scene at different spatio-temporal resolutions. However, in order to benefit from this added information the sources must be temporally aligned. As a result of cost and physical limitations it is often impractical to synchronize these sources via an external clock device.

The area constantly experiences interchanging succession of erosion and accumulation due to natural forces such as wind, wave, and tidal currents. In recent years, associated with fast population increase, the demand of lands expanded rapidly such that the effects on topography of coastal zone became more complex and changed quickly. Coastal sand dunes are dynamic and fragile terrain often regarded as environmentally sensitive areas. Sand dunes are vulnerable to erosion by natural process and human activity. The

There are many landslides in Taiwan due to its fragile geology, abundant rainfall and high population density. The frequency of extreme precipitation and the rainfall intensity are increasing in Taiwan due to the global climate change. It may result in mudslide and landslides. Landslides may become high-risk areas where productivity decline. This study discusses whether land degradation trigged by landslide occurs in Taiwan or not. Meanwhile, we will discover the factors that affect the land

It may easily cause a land crisis, such as floods and salted land. In order to monitor the subsidence behavior and to reduce negative influences, it is necessary to recover the history of land subsidence using multi-sources historical data.Traditional surveying methods for land subsidence monitoring are based on leveling and the setting of monitoring well. These methods generates point-based observations, which hardly present the long-te

Conventionally, change detection in remote sensing depends on expert operators to visually analyze a series of multitemporal images. It usually takes a lot of human labor and time in order to achieve good performance. With development of computer technology, the work by human labor has gradually been accomplished by image processing. We still find it helpful to incorporate some operators’ domain knowledge into the early learning processing for successful change detection.

With radiometric correction/normalization preprocessing, most previous studies utilized temporal and spectral information to develop thresholding-based filters with the aid of a cloud-free reference image.
