Towards Querying And Visualization Of Large Spatio-Temporal Databases, Sugam Sharma

Sugam Sharma

In any database model, data analysis can be eased by extracting a smaller set of the data of interest, called subset, from the mammoth original dataset. Thus, a subset helps enhance the performance of a system by avoiding the iteration through the huge parental data in further analysis. A subset, its specification, or the formal process for its extraction can be complex. In the database community, subsets are extracted through SQL-like queries and through visualization in the Geographic Information System (GIS) community. Both are iterative processes. An SQL query can be a composition of subqueries. Each subquery can be seen …

Toward Renewable Eenergy Geo-Information Infrastructures: Applications Of Giscience And Remote Sensing That Build Institutional Capacity, K. Calvert, Joshua M. Pearce, W. E. Mabee

Joshua M. Pearce

Sustained policy support is necessary in order to drive a transition toward renewable energy (RE). The ability to realize RE policy objectives is constrained by a range of geographic factors related to resource potential, the distribution of resources, land availability/suitability, the absorptive capacity of proximal infrastructure, and local socio-political acceptance. With this in mind, this paper provides a systematic review of how geographic information science and remote sensing techniques have been applied to reduce uncertainties surrounding renewable energy development, with emphasis on policy and planning needs. The concept of a ‘geo-information infrastructure’ is used to bring coherence and direction to …

An Integrated Ahp-Gis-Mclp Method To Locate Bank Branches, Sajjad Allahi, Mohammadsadegh Mobin, Amin Vafadarnikjoo, Christian Salmon

Amin Vafadarnikjoo

One of the most crucial decision making processes in banking is optimally locating new branches. This issue is highly important especially for private banks due to vibrant competition, limited budgets and high customer expectations. This study’s objective is to provide an integrated model for selecting optimal site location using available data sources and well accepted decision models, specifically Analytic Hierarchy Process (AHP), Geographic Information System (GIS) and Maximal Covering Location Problem (MCLP).As a case study, we applied the proposed method for branch location of a private bank in the city of Rasht, Iran. The process identified the most commonly used …

Analysis Of The Spatial And Temporal Dynamics Of Street Hawking: A Case Study Of The Accra Metropolitan Area, Alex Owusu Barimah, Stephen Abrokwah, Stephen Frimpong

Stephen Frimpong

To the street hawker, it is a means of making a living but to the managers of the metropolis, street hawking is a menace. These differences in perception have led to a game plan tied to spatio-temporal diurnal traffic regimes. While the city authorities plan may be to evict the street hawkers, the plan of the hawkers is to outwit the city authorities through make-shift hawking patterns in order to make a living. The difference in the two positions can be characterized by the city manager’s need for clean and less congested city streets, and the hawker’s desire to sell …

Approaching Cave Level Identification With Gis: A Case Study Of Carter Caves, Brianne Jacoby, Eric Wade Peterson, John C. Kostelnick, Toby J. Dogwiler

Eric Wade Peterson

Cave passages that are found at similar elevations are grouped together and called levels. The current understanding is that passages within a level are speleogenetically linked to a common static baselevel or stratigraphic control. Cave levels have provided an interpretive framework for deciphering cave development, landscape evolution, and climatic changes. Cosmogenic dating has been successfully used to interpret levels in Mammoth Cave and the Cumberland Plateau; however, this technique is expensive and there are limited funding resources available. Geographic information systems may be used as preliminary procedures to identify cave levels and constrain the timing of level development. A GIS …

E-Government Challenge In Disaster Evacuation Response: The Role Of Rfid Technology In Building Safe And Secure Local Communities, A. Chatfield, S. F. Wamba, T. Hirokazu

Dr Akemi Chatfield

While geographic information systems (GIS) can provide information on the static locations of critical infrastructure and evacuation routes, they do not provide the dynamically changing locations of things and people on the move. In contrast, radio frequency identification (RFID) wireless network technology can automatically identify and track the movement of assets (i.e., fire engines, ambulances, and rescue workers) and vulnerable citizens on the move (i.e., the elderly and the disabled), and hence providing local governments and communities with real-time information and enhanced decision-making capabilities, during chaotic disaster response operations (i.e., evacuation). Although the potential high impact and strategic value of …

A Pragmatic Gis-Oriented Ontology For Location Based Services, Jun Shen, Aneesh Krishna, Shuai Yuan, Ke Cai, Yuemin Qin

Dr Jun Shen

With advances in automatic position sensing and wireless connectivity, location-based services (LBS) are rapidly developing, particularly in fields of geographic, tourism and logistic information systems. Currently, Web service has been viewed as one of most significant innovations in business industry, and designed on demand to provide spatial related information for LBS consumption. However, the traditional Web Service Description Language (WSDL) cannot meet those requirements, as WSDL is not able to support semantic content and information. In recent years, Ontology came up with an effective approach to enhance service description, automated discovery, dynamic composition, enactment, and other tasks such as managing …

Long term planning could be done for collection, transportation and disposal of SW in such a manner that Waste Collection Points, transportation routes, schedules regarding transportation, loading, unloading, stoppage etc, …

Applicability Of Satellite Remote Sensing And Gis Techniques And Ground Data In Watershed Planning: The Case Of Kubili, Nigeria, Olarewaju Oluseyi Ifatimehin

Olarewaju Oluseyi Ifatimehin

Watershed land and hydrology are resources that are very important in agricultural development. Adequate and proper land use planning and management of these resources is of ultimate importance in sustainable development. In this study remote sensing and Geographic Information System (GIS) techniques were used to generate information on the current status and utilization potentials of the Kubili watershed and generate local specific micro watershed development plans for the area. The study revealed that about 33.25 per cent of the land cover is used for rain fed agriculture that lacks sufficient soil and moisture to support good yield. The drainage density …

Are Home Values Affected By Sinkhole Proximity? Results Of A Hedonic Price Model, Spencer Fleury Ph.D.

Spencer Fleury Ph.D.

Though they lack the high profile and sheer destructive force of hurricanes, floods, and other natural hazards, sinkholes have on occasion generated significant damage to buildings, roads, and other human-built structures, and should be considered natural hazards in their own right. In sinkhole-prone areas where market insurance against sinkhole damage is available, economic theory suggests that homes located there should be valued somewhat lower than homes located in areas where sinkholes are rare or nonexistent, in recognition of both the risk faced by the homeowner in a sinkhole-prone area, and the cost of insuring one’s property against that risk. Working …
