Intensive poultry production is associated with extreme densities of birds crammed into industrial-scale hen houses. Consequently, the bird keepers are exposed to elevated concentrations of dust. Exposure to dust, containing pathogenic mycological agents, may cause exacerbate asthma, allergic alveolitis, as well as organic dust toxic syndrome. Geographic Information System (GIS) allows to view,...

Flood disasters cause massive loss of human lives and immense damage to the infrastructure and economic activities, not only in Turkey but also all over the world. Governments consider several long-term and short-term precautions for flood control. The numerical simulation of dam-break problems could be accomplished with geographic information systems and innovation maps. Spread of the flood wa...

GIS is becoming an essential tool for utility companies, especially water companies, which have found an excellent way to manage and assess their assets. This paper presents an ArcView® GIS extension called GISRed, which is a customized application oriented to the task of water network modelling. GISRed is capable of simulating, analyzing and retrieving the actual network status under certain c...

The planning and support of military naval expeditionary operations relies on precise environmental data, which must be available on time, at the right place and in the requested format. These data sets, usually obtained from a wide number of sensors (satellites, sonars) and models (meteorological and oceanographic), have a common feature: the geospatial component. This paper presents a client-...

DOROTHY ALBRIGHT Fire Response GIS Application Geographic information system (GIS) support for the Incident Command System (ICS) has been evolving over the past several years. The U.S. Forest Service and Firefighting Resources of California Organized for Potential Emergencies (FIRESCOPE) are spearheading an effort to create a standard approach to the problem. The result is an application design...

This paper presents a Geographic Information System (GIS) based cost estimation methodology, which may be helpful in increasing the productivity of quantity estimator by reducing the manual work in quantity takeoffs. Proposed methodology also eliminates missing or duplication of various items of work by visualizing each components corresponding to the items in three dimension (3D). Several scri...

The paper discusses how the well known USACE HEC models, RAS and HMS, are fully integrated within the decision support system of the Romagna River Basins in order to predict flood effects. The models are fully available from the web and cope with such a variety of problems as rainfall-runoff modeling, river and civil works hydraulics, and the mapping of hydraulic hazard. The paper illustrates t...

The design and implementation of software for extracting information from GIS files to a format appropriate for use in a spatial modeling software environment is described. This has resulted in publicly available c/c++ language programs for extracting polygons as well as database information from ArcView shape files into the Matlab software environment. In addition, a set of publicly available ...

Maps of pollutants concentration are usually generated by means of interpolation and extrapolation methods. The quality of the results depends mainly of the number of permanent or temporary measuring stations. This paper deals with a method for the virtual densification of the network of stations. The method creates "virtual measuring stations". It aims at improving the quality of interpolation...
