Abstract Geographic Information Systems (GIS) software is used to analyze rainwater harvesting potential in Escambia County, Florida, USA. The approach presented can be replicated using LiDAR data, and the infrared spectrum of National Agriculture Imagery Program (NAIP) imagery. GIS surface maps are analyzed in combination with local utility consumption data to determine potential reductions in potable water consumption for households. The results indicate an extensive urban catchment of rooftop surfaces, and commensurate potential for rainwater harvesting and stormwater attenuation. Sixty two percent of the households analyzed consumed less water than could be potentially harvested. The remaining 38% consumed more water than could be potentially harvested. There are noted and significant differences between the two sample populations, including differences in water consumed and roof size. A comparison of lot size between the two sample populations did not yield any significant difference. The conclusions indicate that the widespread implementation of rainwater harvesting could substantially reduce potable water use in urban areas, and are of use to policy makers, planners, engineers and property owners everywhere.

Geographic information systems can be defined as a intelligent tool, to which it relates techniques for the implementation of processes such as the introduction, recording, storage, handling, processing and generation of spatial data. Use of GIS in urban planning helps and guides planners for an orderly development of settlements and infrastructure facilities within and outside urban areas. Continued growth of the population in urban centers generates the need for expansion of urban space, for its planning in terms of physical and social infrastructures in the service of the community, based on the principles of sustainable development. In addition urbanization is accompanied with numerous structural transformations and functional cities, which should be evaluated in spatial context, to be managed and planned according to the principles of sustainable development. Urban planning connects directly with land use and design of the urban environment, including physical and social infrastructure in service of the urban community, constituting a challenge to global levels. Use of GIS in this field is a different approach regarding the space, its development and design, analysis and modeling of various processes occurring in it, as well as interconnections between these processes or developments in space.

Operational Capacity

Naturalistic driving can generate huge datasets with great potential for research. However, to analyze the collected data in naturalistic driving trials is quite complex and difficult, especially if we consider that these studies are commonly conducted by research groups with somewhat limited resources. It is quite common that these studies implement strategies for thinning and/or reducing the data volumes that have been initially collected. Thus, and unfortunately, the great potential of these datasets is significantly constrained to specific situations, events, and contexts. For this, to implement appropriate strategies for the visualization of these data is becoming increasingly necessary, at any scale. Mapping naturalistic driving data with Geographic Information Systems (GIS) allows for a deeper understanding of our driving behavior, achieving a smarter and broader perspective of the whole datasets. GIS mapping allows for many of the existing drawbacks of the traditional methodologies for the analysis of naturalistic driving data to be overcome. In this article, we analyze which are the main assets related to GIS mapping of such data. These assets are dominated by the powerful interface graphics and the great operational capacity of GIS software.

AbstractInterest in the past decades in the way spatial cognition manifests in language has led to a growing body of literature on the topic. The concurrent development of user-friendly geographic information systems (GIS) software can give linguists new perspectives on spatial language, especially narratives describing geographic landscapes, by allowing the researcher access to those landscapes in a way that was previously only available by visiting the region in person. In this paper, I discuss how the use of GIS reveals that Ahtna speakers use subtle distinctions in the directional system to structure discourse about overland travel into narrative episodes. Ahtna is an Athabascan language spoken in the Copper River area of southcentral Alaska by about 35 native speakers.

Management Capabilities

<p>Geographic Information Systems (GIS) provide large information management capabilities. However, in many cases the feature of the visualization of this data over a huge detailed three-dimensional terrain does not exist or are limited, wich can be very useful or desirable in many applications. This paper presents the integration of SANTI, a three-dimensional visualization system of large terrain areas and geographical data, with gvSIG, a free GIS software. We describe the capabilities of the visualization system, the approach to connect the two systems and how it is applied to a project in development for the management of the excavation of the Castro de la Lanzada located at the Galician coast (Spain).</p>

Deforestation and land conversion is one of the effects of high nativity rates and urbanizationthat affect the ecological situation.  The imbalance of ecological system become a factor ofincreasing pulmunary Tuberkulosis incidence (TB).  TB is a disease of pulmunary infectionsthat caused by the bacterium Mycobacterium tuberculosis, and it is spread directly.  Thisresearch was conducted to determine the contribution of land use changes incidence of TB inthe Lampung Province.  Land use changes be resultant through landsat imegeryinterpretation utilize Geographic Information Systems (GIS) software.  Parameter usedstatistical software, used the F test on the real level of 10%.  The result showed that therewere several factors that have real influence, namely; community forest with a coefficient of 1.0314(Pvalue=0.040), Clean and Healthy Lifestyle (PHBS) coefficient of -0.3691 (Pvalue=0.042), density population coefficient of 0.011661 (Pvalue=0.008) and the percentage of poorresident coefficient of 0.6641 (Pvalue=0.006).  While forest, plantation, developed land, healthfacility and healthy house did not have significant effect toward incidence of TB in Lampung Province.Keywords : deforestation, geographic information systems(GIS), incidence of TB, land use.
