ABSTRACT

Use of GIS in public health is currently limited to tracking immunizations, disease surveillance, and establishing new service areas. The potential of GIS to improve planning, implementation and monitoring of programs and to inform policymaking processes for universal access to healthcare is grossly underutilized. Major reasons for restricted use are paid access to GIS software and difficult interpretation for non-GIS professionals. WebGIS technologies present an opportunity for non-GIS public health professionals to present complex data and findings in simpler manner. Conventional GIS methods and Geovisualization are compared and contrasted in this paper using data from the MATIND project in the Gujarat state of India. In-depth literature review on GIS techniques used in health implementation research was conducted. In this paper, MATIND data have been used for comparing conventional GIS methods with a newer web based GIS tool-Geovisualization. GIS software is more useful for analytical purposes; whereas web based geovisualization techniques are much better for visualization and easy interpretation of results by non GIS public health researchers. As the images are easy to interpret, interactive/dynamic and not much technical expertise is required to perform basic analysis, the tool is useful for policy makers and planners. Geovisualization provides a user-friendly tool for presenting large scale community based survey data. Increased use of this tool will help to present implementation research in a creative way to the program planners and policy makers. For program managers, it is a useful tool to monitor implementation and impact of a program to improve health of population.

ABSTRACT

The main aim of this work is to describe in detail how to develop an instrument, with the goal of collecting and managing a great deal of both geological and geophysical data acquired using different survey typologies in Eastern Sicily (Italy). The opportunity to manage different categories of data, at the same time, allows us to have a complete view of the complex area studied. This paper discusses a software package that has been designed to enhance the efficiency of applying a range of geological and geophysical data. More than 12000 records are archived: boreholes represent 81% of the data and 19% is geophysical data. In this paper it is illustrated how both kinds of data, thanks to the functionalities of the database and the possibility of connecting to a Geographical Information System (GIS), can be used in a variety of different geological studies. We present four studies where is relevant the use of the database, in detail, we show a morpho-structural study, an examination of the spectral analysis of the noise data, an update of the geological and geotechnical maps, and a classification of the areas on the basis of the distribution of the shear wave velocity in the firsts 30 meters (Vs30). They are just some examples of the potentialities of a relational database.

ABSTRACT

Flash flooding is one of the periodic geohazards in the southern Red Sea Coast. However, their freshwaters are the main source of recharging alluvial and fractured aquifers. This paper presents hydrological and geomorphologic classification of Wadi El-Gemal, Wadi Umm El-Abas, Wadi Abu Ghuson and Wadi Lahmi, along the southeastern Red Sea Coast in Egypt. The main goal is to find a relationship of flash floods and groundwater recharge potentials. Satellite imageries and topographic data were analysed via remote sensing and GIS techniques. The main four valleys’ orders range from six to seven. Wadi El-Gemal was the main focus of this study; it is characterized by high stream frequency, low stream density and coarse texture, reflecting influence of highly fractured Precambrian rocks. Most of the wadis have umbrella-shaped catchment areas, due to the influence of NW-SE Najd Fault System and late E-W strike-slip faults. The main wadis were divided into 45 sub-basins. 14 of the studied sub-basins flow into Wadi El-Gemal, 7 flow into Wadi Umm El-Abas, 10 are in Abu Ghuson, and rest of the basins flow into WadiLahmi. A conceptual model was used in this study, showing that most of the sub-basins have high flash flooding and low groundwater recharge potentials. However, only two sub-basins have low potential of flooding and high potential of groundwater recharge, whereas few sub-basins have moderate potential of groundwater recharge as well as flooding. For flash floods beneficiation and mitigation, construction of multifunctional embankment dams is imminent.

ABSTRACT

Objective: The Ministry of Health Malaysia is developing a GIS database of health facilities in the country with the main aim to assist in the planning and development of the services, and in allocation of resources. Methodology: Apart from coordinates of the facilities, other digital information such as states and districts boundaries, main road networks and river were obtained from MacGDI, a centre responsible to manage geospatial data infrastructure in Malaysia. In assisting the Ministry of Health in its planning, one of the analyses that were conducted was a flood simulation analysis in a district in a coastal area of Peninsular Malaysia. This was done following a possibility that a tropical storm “Sonamu” would happen in that area. The objective was to identify health facilities that would be affected if a flood were to happen in the district and finally to assist the Ministry of Health in their emergency plan. Data on contour was obtain from a relevant government agency and was also mapped digitally. Results: The results were showing that with one metre depth of flood, more than half of the facilities would be affected and about two third of the facilities would be affected if the flood level rises to 2.5 metres. Conclusion: Application of GIS is very useful for the health sector in planning of facing an environmental related disaster.

ABSTRACT

The area with the fastest growing Native American population in North Dakota is the Fort Berthold Reservation. State and federal road information available to the public is not identical in terms of the number of physical road segments or in the attribute information provided for the road network. In this study we develop: 1) a navigable road network achieved by improving connectivity between road segments, updating road information, and making a comprehensive network; and 2) a standard process for integrating the state and federal local road information. The standard process broadly consists of three Parts: 1) combining road segments from each source; 2) providing legitimacy to snapping distance; and 3) performing a snapping based on the result of Part 2 to connect those road segments, which remained unconnected from Part 1. The findings show that data on local roads on the Fort Berthold Reservation from the two different sources are joined through the standard process, and the process saves considerable time and resources required for fixing the road network. The standard process that has been developed here can be applied to a variety of other Indian road information integration projects to join not only physical road segments, but also plural attribute information. The process will also be useful for a variety of other projects integrating road information, which is available to the public, in order to overcome financial and time limitations.

http://www.scirp.org/journal/PaperInformation.aspx?PaperID=50655#.VEhT9VfHRK0

ABSTRACT

CO is one of the main air pollutant which leads to many problems for human. Mega cities such as Tehran have critical issues by increasing the vehicles, fuel usage and urban area expansion. Hence, to have a clear view points on the pattern of CO concentration in Tehran, the data of 14 air quality concentration centers in a midterm period (2009 and 2012) are used. The main novelty of this research is using the third quartile (Q3) as the pollution indicator which leads to more accurate results based on the exposure pattern in a day. Additionally, by Spline interpolation model and using ArcGIS software the zoning maps to show the CO concentration in urban area are illustrated and discussed. Using Q3 instead of the mean values showed more accurate results due to the exposure patterns. Due to the results, the CO concentration shows a downward trend and the most changes are in the Western side of the city.

eHealth Management Platform for Screening and Prediction of Down’s Syndrome in the Republic of Panama.

ABSTRACT

Through engineering projects, we have integrated software engineering, geographical information systems and HL7 standard to propose a model of an eHealth management platform for Down’s syndrome screening, replicable in all the country. It will use real time sample information acquired from the local population and will geographically reference this information in the territory of Panama for future research.
