Evacuation Route

Floods in Pekanbaru City have often hit the region along the Siak river, including the Rumbai subdistrict. Disasters such as floods have detrimental impacts on society, including a massive loss of lives. However, several strategies can minimize the impacts of flooding, including making a plan evacuation route mapping with Geographic Information Systems (GIS). This is a planning-based analysis of data using the algorithm djikstra for result pathways for efficient and effective evacuation. The evacuation routes involve seven simulation parameter modeling, specifically flood, length path, wide roads, road conditions, road materials, presence or absence of bridges, and the road’s direction. These parameters are processed using algoritma djikstra to generate the appropriate evacuation routes based on study area conditions. The analysis focuses on one evacuation route in Palas and the other six in Sri Meranti Village. The routes in Palas Village lead to the evacuation place of the Al-Jihad Mosque, while those in Sri Meranti Village heads to Al-Ikhlas Mosque, MDA Aula Rumbai, Nurul Haq Mosque, M Nurul Mosque, vacant land, and Stadium Parking Area.

The aim of the study is the determination of socio-economic characteristics of the elderly, emphasizing the usefulness of Geographic Information Systems (GIS) to explore the socio-economic indicators that affect the health level of the elderly. Given the usefulness of GIS and their application in the fields of physical health, mental health, health services and general health management, a survey for the investigation of the socio-economic indicators that affect the health level of the elderly was carried out, using a specially designed questionnaire. The results of this survey were plotted in the corresponding geographical locations on the maps, giving the person concerned a full picture of the geographical distribution of socio-economic indicators that affect the health level of the elderly.

Studies of aquifer favorability have been developed to reduce uncertainty in water well location and to define the hydrogeological potential of crystalline aquifers. The use of geoprocessing tools and Geographic Information Systems (GIS) proved efficient in determination of areas with a higher hydrogeological potential. The area of study is the São Domingos River Basin (SDRB), located in the Northwestern Region of Rio de Janeiro State, Brazil, including the entire São José de Ubá and a small part of Itaperuna municipalities. The main objective is to determine the hydrogeological favorability of the SDRB as a contribution to the management of the region's water resources, as well as elaborate a methodology to produce a cartography of hydrogeological favorability. As a result, hydrogeological favorability maps of SDRB were elaborated, comprising five classes of favorability, with two great domains: the central portion presenting classes of higher favorability and the upper basin with classes of lower favorability. The conclusions are: 1) favorability of the SDRB is strongly conditioned by the basin's geologic-structural settings; 2) the method used proved efficient in the evaluation of the fractured aquifers favorability.

Mining Methods

This article reviews the approaches used in data mining to perform a geographical study of regional datasets coupled with Geographic Information Systems (GIS). Firstly, we can look at the functions of data mining used by such data and then illustrate their precision compared to their classic data use. We will further explain the research conducted in this sector and point out that two separate methods exist: one is focused on space database learning while the other is based on space statistics. Finally, we will address the key distinctions between these two methods and their similar features.

Area Of Interest

Accelerated water erosion is the major problem of agricultural soils all over the world and also in the Slovak Republic. Accelerated erosion occurs in 55 % of agricultural land. It belongs to physical degradation of fertile land, and the whole process is irreversible. Therefore, it is very important to localize the presence of accelerated erosion and apply the basic principles of soil erosion control. Geographic information systems (GIS) are an effective tool for various environmental analyses, so it can also be succesfully used for determination of potential erosion intensity. The aim of this work was to create a map of domain areas that describes potential water erosion. As an area of interest the cadastral territory of Topolcianky in the Slovak Republic was selected. For this purpose the GIS software Arcview from ESRI was used. Water erosion process was modelled by universal soil loss equation (USLE) which computes an average annual soil loss. The limit values of acceptable intensity of soil loss are defined in the Collection of Laws of the Slovak Republic (Act No 220/2004 Coll). The final result of this work is a map that divides the domain area according to potential annual soil loss into several categories. In this case the domain area was divided into four categories. The first category, named slightly threatened soil, had 620,05 ha of agricultural land (77,48 per cent of the total agricultural land of domain area). The second category, called averagely threatened soil, had 106,56 (13,32 per cent of the total agricultural land). The third category (intensively threatened soil) had 70,91 ha (8,86 per cent of the total agricultural land) and finally the fourth category (very intensively threatened soil) had 2,74 ha (0,34 per cent of the total agricultural land).

Different Levels

Geographic information systems are largely used in different levels of administration and planning where geo-referenced information is a crucial factor behind analysis and determination of different decision-making scenarios. The potential of these systems is increasingly being perceived as a support to facilitate public participation in planning processes.
