The objective of the research was to test the applicability of an advanced classification method for hyper-spectral images of natural vegetation. The advanced method is an integration of image segmentation and classification, originally developed for multi-spectral images of agricultural areas. Here, this method provides improved classification,...

Subsurface firn processes play a crucial role in ice sheet mass loss mechanisms. On Greenland surface meltwater percolates to deeper layers where porous firn retains it, directly inhibiting runoff. However, secondary effects such as the formation of impermeable ice slabs may indirectly and irreversibly accelerate runoff and with it global sea...

The biofuel consumption in Brazil is increasing rapidly. This leads to an expansion of sugarcane production, since this crop is the main source for the bio-based fuel. In order to assess the sustainability of this development, its resulting land use changes have to be investigated. Currently, the sugarcane expansion is tracked manually and on a...

The Black Desert in the east of Jordan has recently gained attention in the archaeological domain due to the discovery of pre-historical structures and a vast amount of rockart depictions. The Department of Near Eastern Archaeology of the University of Leiden has started investigating the cultural developments within this area from c. 1000 BC to...

Coastal squeeze is defined as the reduction in the space of coastal habitats to operate [1] and it is an important cause for (amongst others) coastline retreat, an increase in flood risk and salinity intrusion. Land use changes, such as deforestation and urbanization, reduce the space of natural habitats such as mangrove forests. This causes a...

A large-scale nourishment known as the Sand Motor has been implemented along the Dutch coast as a Building with Nature solution designed for the upcoming 20 years. Given the long-term period of the project, a combination of in situ measurements and remote sensing techniques are currently in use. An X-band radar system is deployed at the Sand...

The coastal area provides important services such as valuable habitats for wildlife, resources for regional development, and buffer zones for the land against natural disasters such as storm surges. But these narrow coastal areas experience pressure from both land and ocean side. In order to regulate sustainable coastal development, protect...

Effective urban water management requires certainty about surface conditions such as the surface infiltration capacity (SIC). A SIC map of an urban catchment area could be a useful input for evidence-based urban design of water-sensitive/low-impact neighbourhoods and multitiered water management schemes for reducing flood vulnerability. Methods...

The persistent scatterer interferometry (PSI) is a relatively new technique in radar interferometry which has matured, within a last decade, to a practical technique for measuring the deformation of the Earth’s surface. PSI overcomes the main limitations of conventional InSAR methods by identifying radar targets, called persistent scatterers (PS...

Understanding the river dynamics is very important to be able to make use of all river functions and to protect ourselves against floods. Hydrodynamic models are used to predict river behaviour and one of the input parameters is the river geometry. In-situ measuring of river geometry can be very expensive and time consuming. Remote sensing...

Currently available land and water use maps don’t meet the needs of hydrologists and water managers in many cases, particularly in developing countries. Existing maps often lack the resolution and detail required by hydrological models, and those that do meet requirements are limited in spatial coverage. The research presented in this report...

In hydrological models evaporation is often still quite uncertain. Potential evaporation is used as input, but the modelling of plant stresses is not always accurate enough to describe the behaviour in reality. In situ measured actual evaporation data is rare, and doing measurements is time consuming and expensive. With the advance of satellite...

The coastal area is a dynamic environment that suffers from human interventions and climate change. This requires extensive research and monitoring of the coastal areas. Measurement systems play a key role in the monitoring. Current velocities are for example often measured to investigate local hydrodynamics. At the moment the ADCP is often used...

Several factors play a role in the ongoing process of the acceptance and eventual universal use of LiDAR remote sensing technology in wind site assessment. Especially turbulence parameter 푇퐼 is still giving food for thought. Three important aspects of LiDAR measured 푇퐼 that are considered key are picked out and feature in this work, which...

A satellite remote sensing technique, Interferometric Synthetic Aperture Radar (InSAR), is able to provide surface displacement information on a millimeter level. In this study, data from the TerraSAR-X satellite collected in the years 2009-2018 over the area of Amsterdam is used. Even though radar data is a subject to multi-step processing,...

Lidar systems can provide vertically resolved measurements of the physical and optical properties of the atmospheric particles with high spatiotemporal resolution. In this study, four case studies were analyzed and studied in order to identify the dominant aerosol type over the city of Nicosia in Cyprus: 05 April and 07 April 2015 and 17 April...

This research is focused on the feasibility assessment of a novel technology of metasurfaces in order to design a spectropolarimeter with the thickness of a few micrometers integrated on the detector array. The motivation behind the research is miniaturization of state-of-the-art spectropolarimeters. The requirements for the instrument are...

A new semi-supervised `growing' Bayesian classifier for small reservoir delineation has been developed and is tested with Radarsat-2 data for reservoirs in the semi-arid Upper East Region of Ghana. The classifier reduces the confusion error to the land-water boundary pixels, can readily be extended with auxiliary information and has a high...
