  • 3D modeling of building indoor spaces and closed doors from imagery and point clouds

    • Authors: Díaz-Vilariño, Lucía;  Advisor: -;  Participants: - (2015)

  • 3D models of indoor environments are increasingly gaining importance due to the wide range of applications to which they can be subjected: from redesign and visualization to monitoring and simulation. These models usually exist only for newly constructed buildings; therefore, the development of automatic approaches for reconstructing 3D indoors from imagery and/or point clouds can make the process easier, faster and cheaper. Among the constructive elements defining a building interior, doors are very common elements and their detection can be very useful either for knowing the environment structure, to perform an efficient navigation or to plan appropriate evacuation routes. The fact that doors are topologically connected to walls by being coplanar, together with the unavoidable pre...

  • Adjusting spectral indices for spectral response function differences of very high spatial resolution sensors simulated from field spectra

    • Authors: Cundil, Sharon L.;  Advisor: -;  Participants: - (2015)

  • The use of data from multiple sensors is often required to ensure data coverage and continuity, but differences in the spectral characteristics of sensors result in spectral index values being different. This study investigates spectral response function effects on 48 spectral indices for cultivated grasslands using simulated data of 10 very high spatial resolution sensors, convolved from field reflectance spectra of a grass covered dike (with varying vegetation condition). Index values for 48 indices were calculated for original narrow-band spectra and convolved data sets, and then compared. The indices Difference Vegetation Index (DVI), Global Environmental Monitoring Index (GEMI), Enhanced Vegetation Index (EVI), Modified Soil-Adjusted Vegetation Index (MSAVI2) and Soil-Adjusted ...

  • Adapting Scotland’s forests to climate change using an action expiration chart

    • Authors: Petr, M.;  Advisor: -;  Participants: - (2015)

  • The inherent uncertainty of climate change impacts is one of the main challenges for adaptation in environmental management. The lack of knowledge about climate impacts on ecosystem services at high spatial and temporal resolution limits when and what adaptation measures should be taken. We addressed these limits by assessing four ecosystem services—forest production, tree growth, sequestered carbon, and tourism potential—under drought or climate change. To support adaptation, we adapted the existing concept of ‘dynamic adaptive policy pathways’ for forest management by developing an action expiration chart, which helps to define expiry dates for forestry actions using ecosystem services delivery thresholds. We assessed services for Sitka spruce, Scots pine, and pedunculate oak on t...

  • Climate-Determined Suitability of the Water Saving Technology "Alternate Wetting and Drying" in Rice Systems :A Scalable Methodology demonstrated for a Province in the Philippines

    • Authors: Nelson, Andrew;  Advisor: -;  Participants: - (2015)

  • 70% of the world’s freshwater is used for irrigated agriculture and demand is expected to increase to meet future food security requirements. In Asia, rice accounts for the largest proportion of irrigated water use and reducing or conserving water in rice systems has been a long standing goal in agricultural research. The Alternate Wetting and Drying (AWD) technique has been developed to reduce water use by up to 30% compared to the continuously flooded conditions typically found in rice systems, while not impacting yield. AWD also reduces methane emissions produced by anaerobic archae and hence has applications for reducing water use and greenhouse gas emissions. Although AWD is being promoted across Asia, there have been no attempts to estimate the suitable area for this promising...

  • CoastColour Round Robin data set :a database to evaluate the performance of algorithms for the retrieval of water quality parameters in coastal waters

    • Authors: Nechad, B;  Advisor: -;  Participants: - (2015)

  • The use of in situ measurements is essential in the validation and evaluation of the algorithms that provide coastal water quality data products from ocean colour satellite remote sensing. Over the past decade, various types of ocean colour algorithms have been developed to deal with the optical complexity of coastal waters. Yet there is a lack of a comprehensive intercomparison due to the availability of quality checked in situ databases. The CoastColour Round Robin (CCRR) project, funded by the European Space Agency (ESA), was designed to bring together three reference data sets using these to test algorithms and to assess their accuracy for retrieving water quality parameters. This paper provides a detailed description of these reference data sets, which include the Medium Resolu...

  • Earth observation as a tool for tracking progress towards the Aichi Biodiversity Targets

    • Authors: O'Connor, Brian;  Advisor: -;  Participants: - (2015)

  • Biodiversity is continuing to decline. This crisis has been recognised by the Convention on Biological Diversity (CBD), whose members have set ambitious targets to avert ongoing declines in the state of biodiversity by 2020. These so called “Aichi Biodiversity Targets” (ABTs) are organized around five strategic goals, with indicators showing the level of progress made towards each target. Currently, measurements of many ABT indicators are not available. The Essential Biodiversity Variable (EBV) framework, developed by the Group on Earth Observations Biodiversity Observation Network (GEO BON), attempts to form a coherent and harmonised set of observations of biodiversity. In this paper, we explore the potential role of Earth Observation (EO) as a tool to support biodiversity monitori...

  • Equity - based resource allocation for infrastructure development

    • Authors: van Maarseveen, M.F.A.M.; Wismadi, A.;  Advisor: -;  Participants: - (2015)

  • Thesis discusses the policy context of addressing social and spatial equity for equitable infrastructure; discloses the shortcoming of social equity measurements and describes the existing social equity measurement methods to be applied in infrastructure development; examines the effect of place‐based policy on infrastructure and economic interaction and serves as a basis to justify the need to establish a formal method to operationalize place‐based policy into resource allocation modelling; establishes a new approach to implement a place‐based resource allocation policy in a Spatial Decision Support Systems and compares its effectiveness to address spatial equity against people‐centred policy; compares the agreement of a place‐based and people‐centred policy to planning objectives ...
