Mapping Local Climate Zones for a Worldwide Database of the Form and Function of Cities
Tập 4 Số 1 - Trang 199-219
Progress in urban climate science is severely restricted by the lack of useful
information that describes aspects of the form and function of cities at a
detailed spatial resolution. To overcome this shortcoming we are initiating an
international effort to develop the World Urban Database and Access Portal Tools
(WUDAPT) to gather and disseminate this information in a consistent manner for
urban a...
User-Generated Geographic Information for Visitor Monitoring in a National Park: A Comparison of Social Media Data and Visitor Survey
Tập 6 Số 3 - Trang 85
Protected area management and marketing require real-time information on
visitors’ behavior and preferences. Thus far, visitor information has been
collected mostly with repeated visitor surveys. A wealth of content-rich
geographic data is produced by users of different social media platforms. These
data could potentially provide continuous information about people’s activities
and interactions wi...
Parameters Derived from and/or Used with Digital Elevation Models (DEMs) for Landslide Susceptibility Mapping and Landslide Risk Assessment: A Review
Tập 8 Số 12 - Trang 545
Digital elevation models (DEMs) are considered an imperative tool for many 3D
visualization applications; however, for applications related to topography,
they are exploited mostly as a basic source of information. In the study of
landslide susceptibility mapping, parameters or landslide conditioning factors
are deduced from the information related to DEMs, especially elevation. In this
paper cond...
A Conceptual Flash Flood Early Warning System for Africa, Based on Terrestrial Microwave Links and Flash Flood Guidance
Tập 3 Số 2 - Trang 584-598
A conceptual flash flood early warning system for developing countries is
described. The system uses rainfall intensity data from terrestrial microwave
communication links and the geostationary Meteosat Second Generation satellite,
i.e., two systems that are already in place and operational. Flash flood early
warnings are based on a combination of the Flash Flood Guidance method and a
hydrological...
Registration of Multi-Level Property Rights in 3D in The Netherlands: Two Cases and Next Steps in Further Implementation
Tập 6 Số 6 - Trang 158
This article reports on the first 3D cadastral registration in The Netherlands,
accomplished in March 2016. The solution was sought within the current
cadastral, organisational, and technical frameworks to obtain a deeper knowledge
on the optimal way of implementing 3D registration, while avoiding discussions
between experts from different domains. The article presents the developed
methodology to...
A SMAP Supervised Classification of Landsat Images for Urban Sprawl Evaluation
Tập 5 Số 7 - Trang 109
The negative impacts of land take on natural components and economic resources
affect planning choices and territorial policies. The importance of land take
monitoring, in Italy, has been only recently considered, but despite this
awareness, in the great part of the country, effective monitoring and
containment measures have not been started, yet. This research proposes a
methodology to map and mo...
Machine Learning Techniques for Modelling Short Term Land-Use Change
Tập 6 Số 12 - Trang 387
The representation of land use change (LUC) is often achieved by using
data-driven methods that include machine learning (ML) techniques. The main
objectives of this research study are to implement three ML techniques, Decision
Trees (DT), Neural Networks (NN), and Support Vector Machines (SVM) for LUC
modeling, in order to compare these three ML techniques and to find the
appropriate data represe...
Towards a Standard Plant Species Spectral Library Protocol for Vegetation Mapping: A Case Study in the Shrubland of Doñana National Park
Tập 4 Số 4 - Trang 2472-2495
One of the main applications of field spectroscopy is the generation of spectral
libraries of Earth’s surfaces or materials to support mapping activities using
imaging spectroscopy. To enhance the reliability of these libraries, spectral
signature acquisition should be carried out following standard procedures and
controlled experimental approaches. This paper presents a standard protocol for
the ...
Identifying Building Functions from the Spatiotemporal Population Density and the Interactions of People among Buildings
Tập 8 Số 6 - Trang 247
Buildings are fundamental components of cities. Understanding the function of
buildings is therefore of great importance for urban development and management.
Some studies have identified building functions using spatiotemporal data, which
assumes that buildings with the same function have similar temporal activity
patterns. However, these methods present difficulties in coping with the
situation ...
Modelling Sediment Retention Services and Soil Erosion Changes in Portugal: A Spatio-Temporal Approach
Tập 10 Số 4 - Trang 262
Soils provide important regulating ecosystem services and have crucial
implications for human well-being and environmental conservation. However, soil
degradation and particularly soil erosion jeopardize the maintenance and
existence of these services. This study explores the spatio–temporal
relationships of soil erosion to understand the distribution patterns of
sediment retention services in mai...
