Spatial Estimations Of Air Pollution In Urban Areas By Lidar Measurements, L. Matejicek
Spatial Estimations Of Air Pollution In Urban Areas By Lidar Measurements, L. Matejicek
International Congress on Environmental Modelling and Software
Spatial analysis and visualization of data focused on air pollution in urban areas can be more efficiently explored by geographic information systems (GISs). Data originating from direct monitoring, mathematical modelling and physical simulation in wind tunnels are represented by a wide range of data formats that, together with spatial objects on the surface of studied areas, form heterogenic structures. Thus, to solve spatio-temporal analysis and numeric models, a complex computer system is needed to manage the data and a number of user oriented procedures. In the case of this contribution, a GIS project is developed to examine the GIS abilities …
Spatial And Temporal Model Validation: Representing Landscape Properties And Processes Across Scales, C. S. Renschler
Spatial And Temporal Model Validation: Representing Landscape Properties And Processes Across Scales, C. S. Renschler
International Congress on Environmental Modelling and Software
Continuous modeling of landscape processes and their validation requires representingenvironmental properties for model input and output across scales. A combination of a scaling theory, aGeospatial Project Management Tool (GeoProMT), and a GIS-based environmental modeling interface,allows interdisciplinary collaborators to efficiently handle and communicate the scaling (or transformation)of geospatial information of properties and processes across scales. This integrated approach of theory,project management tool, and modeling interface can be applied to any environmental model and softwaredevelopment. The integrated modeling is based on the Geospatial Interface for the Water Erosion PredictionProject (GeoWEPP) that enables soil and water conservationists to assess soil erosion taking into …
A Gis-Based Framework To Model Farm And Landscape Scale Indicators For Sustainable Rural Development, C. Kjeldsen, Tommy Dalgaard, P. K. Bøcher
A Gis-Based Framework To Model Farm And Landscape Scale Indicators For Sustainable Rural Development, C. Kjeldsen, Tommy Dalgaard, P. K. Bøcher
International Congress on Environmental Modelling and Software
Facilitation of sustainable rural development has a high priority on the European Union policy agenda and extensive research on this subject has been started. This paper presents results from the strategic EU research project MEA-scope (www.MEA-scope.org), and the development of a GIS-based framework to model farm and landscape scale indicators for rural sustainability. Problems in scaling information between the farm- and the landscape levels in particular are addressed. Both aggregation and disaggregation techniques are needed to convey information between the two levels. This is demonstrated in a case study of (1) landscape level aggregation of farm level information, from statistics …

Spatial Estimations Of Air Pollution In Street Canyons By Lidar Measurements, L. Matejicek, Jana Konradova
International Congress on Environmental Modelling and Software
Air pollution of urban areas can be explored by direct monitoring, mathematical modeling and physical simulation in the wind tunnels. Complex analysis requires using of all mentioned approaches together. To integrate the data inputs and outputs, which include spatio-temporal interactions, the Geographic Information System (GIS) is used for database management and spatial analysis. The geodatabase is primarily developed to support spatial interpolations of LIDAR measurements in the street canyons. The LIDAR measurements provide the information about the distribution of pollutants in the points along the beam trajectories. As the examples, the sets of NO2 spatial measurements are performed in the …
Modelling Of Water Pollution In Urban Areas With Gis And Multivariate Statistical Methods, L. Matejicek
Modelling Of Water Pollution In Urban Areas With Gis And Multivariate Statistical Methods, L. Matejicek
International Congress on Environmental Modelling and Software
Integrating modelling of water pollution and GIS enables the connection of environmental process models with geospatial data describing the physical environment. Time series of water pollution data at monitoring profiles are used to complement the spatial database and to interpret the results of data analysis. In this case, the multivariate statistical methods provide an exploratory environment for data analysis and an indication of seasonal changes in the framework of surface water pollution. In addition to a wide range of useful multivariate methods, principal component analysis (PCA) and factor analysis (FA) are used to differentiate seasonal water pollution at monitoring profiles. …
Logisnet: A Tool For Multimethod, Multilayer Slope Stability Analysis, G. Legorreta Paulin, M. I. Bursik
Logisnet: A Tool For Multimethod, Multilayer Slope Stability Analysis, G. Legorreta Paulin, M. I. Bursik
International Congress on Environmental Modelling and Software
Shallow landslides or slope failures have been studied from several points of view. In particular, numerous methods have been developed to assess slope stability. However, little work has been done on the systematic comparison of different techniques, and the incorporation of vertical contrasts of geotechnical properties in multiple soil layers. In this research, stability is modeled by using LOGISNET, an acronym for logistic regression, Geographic Information System and Neural Network. LOGISNET is a project of which the main purpose is to provide government planners and decision makers a tool to assess landslide susceptibility. The system is fully operational for models …

International Congress on Environmental Modelling and Software
The Automated Geospatial Watershed Assessment (AGWA) tool is a GIS-based hydrologic modeling tool developed jointly by the U.S. EPA Office of Research and Development, USDA Agricultural Research Service, and University of Arizona. It was initially designed as a research tool for assessing the hydrologic impacts associated with landscape change at multiple scales, a context in which process-based models are a necessity. As potential management applications of the tool became more readily apparent and partners with specific management objectives were identified, AGWA was transformed into a highly versatile tool for environmental management and planning. A thoughtful software design facilitates linkages between …

Web-Based Open Source Gis Decision Support Tools: Explaining The Software Stack, Aaron Racicot
International Congress on Environmental Modelling and Software
As the analytical processing capabilities of software systems grow, so do the expectations of end users of those software systems. An ever increasing trend has emerged in the software domain to provide more functionality over the World Wide Web through web services. Web-based decision support tools are emerging as a viable solution to fulfill environmental management decision support needs, while addressing the desire for platform independent web-based interfaces. Managers of environmental systems are often held hostage to the lack of information about the very system they manage. While modeling techniques and capabilities continue to grow, the need for real-time decision …

International Congress on Environmental Modelling and Software
In this paper we present a systematic approach to the development of the lava flow hazard map forthe Mount Etna, the most important active volcano in Europe. The basic idea is to determine the hazard zonesby simulating the lava flows originated from a number of sample points localized in regions at high densityof vents, called eruption zones. The key choice is the adoption of a probabilistic model for the simulation ofthe lava flow. In the paper we outline the characteristics of the model, called ELFM, and how it has beenvalidated. On the other side, for the determination of the eruption …
