Spatial Data Development at the Bureau of Transportation Statistics Track: Transportation Author(s): Matthew Sheppard, Patricia Solano, Raquel Wright The Bureau of Transportation Statistics (BTS) is leveraging ArcGIS and ArcIMS tools for critical spatial data development efforts. BTS has implemented an ArcIMS application designed to facilitate the collection and quality review of nonattainment ...

Estuaries are ecologically and economically valuable and have been highly degraded from both land and sea. Estuarine habitats in the coastal zone are under pressure from a range of human activities. In the United States and elsewhere, very few conservation plans focused on estuaries are regional in scope; fewer still address threats to estuary long term viability.We have compiled basic informat...

Recent improvements in mobile device technology make the vision feasible to have geodata analyzed by users right in the field. However, the current practice in mobile applications only allows to gather new data and to retrieve them for viewing on the mobile device. In the future, update capabilities for retrieved data are indispensable. We regard a mobile geo application as being fully integrat...

The paper presents a spatial information system (SIS) developed in the research project, “Tecniche murarie tradizionali: conoscenza per la conservazione ed il miglioramento prestazionale” (Traditional building techniques: from knowledge to conservation and performance improvement), with the aim of archiving and managing the data derived from the project. The research project has the purpose of ...

This paper introduces the results of integration of lexical and terminological resources, most of them developed within the Human Language Technology (HLT) Group at the University of Belgrade, with the Geological information system of Serbia (GeolISS) developed at the Faculty of Mining and Geology and funded by the Ministry of the Environmental protection. The approach to GeolISS development, w...

Abstract—During the last decade Panicum virgatum, known as Switchgrass, has been broadly studied because of its remarkable attributes as a substitute pasture and as a functional biofuel source. The objective of this investigation was to establish soil suitability for Switchgrass in the State of Mississippi. A linear weighted additive model was developed to forecast soil suitability. Multicriter...

Background Visceral leishmaniasis is one of the most important vector borne diseases in the world, transmitted by sand flies. Despite efforts to prevent the spread of the disease, cases continue worldwide. In Iran, the disease usually occurs in children under 10 years. In the absence of timely diagnosis and treatment, the mortality rate is 95-100%. The main objective of this study was to determ...

This paper illustrates and discusses the key issues of the geographical information system (GIS) developed by the Unit of Veterinary Epidemiology of the Veneto region (CREV), defined according to user needs, spatial data (availability, accessibility and applicability), development, technical aspects, inter-institutional relationships, constraints and policies. GeoCREV, the support system for de...

Travel diary data (TDD) is an important disaggregate data source for transportation research. It is an example of multi-dimensional data that combines spatial, temporal, and attribute information. A proper representation of TDD can help researchers extract useful information from the data set. Current GIS is mainly designed to handle spatial and attribute data, lacking the representation of tem...

The aim of this study was to map soil erosion on the Mediterranean island of Cyprus. The G2 model, an empirical model for month-time step erosion assessments, was used. Soil losses in Cyprus were mapped at a 100 m cell size, while sediment yields at a sub-basin scale of 0.62 km2 mean size. The results indicated a mean annual erosion rate of 11.75 t ha−1 y−1, with October and November being the ...
