Geographic information systems provide a high level of functionality for spatial analyses but are not yet able to provide extended functionality needed to create a truly "scientific GIS". Functionality that is lacking include time series analyses, calculation of the volume of the overlap between two volumes or calculation of the intersection of a vector path with a volume. Other functions inclu...

Waste collection and transportation is considered as the most costly stage of waste management, to the extent that more than 70% of the total waste management costs are related to this sector. The aim of this study was to analyze the cost of the waste collection and transportation system of the 5th district of Tabriz, Iran, in 2015. For this purpose, the maps of collection routes and locations ...

One of the main challenges for transportation engineers is the consideration of pedestrian safety as the most vulnerable aspect of the transport system. In many countries around the world, a large number of accidents recorded by the police are composed of accidents involving pedestrians and vehicles, for example when pedestrians may be struck by passing vehicles when crossing the street. Carefu...

Using ArcGIS Topology Rules for Improving Data Maintenance for Navy PWCs Track: Defense and Intelligence Author(s): Dale Dunham The Public Works Centers in Navy Regions Japan and Hawaii had converted their GIS data maintenance process to the SDE Geodatabase environment realizing significant efficiencies. With the release of Topology rule-based editing in ArcGIS 8.3, significant process improvem...

Many decision tasks in disaster management are concerned with spatial patterns and spatial decision problems often require that a large number of feasible alternatives be evaluated based on multiple criteria. Although Geographical Information Systems (GIS) provide extensive spatial analysis and data visualization power to users, such systems offer a limited capacity for tackling complex spatial...

Las cuencas hidrográficas son muy importantes porque facilitan la recolección de los recursos hídricos agua dulce y se considera un elemento esencial dentro del ciclo vida. El presente trabajo realizó con finalidad determinar las características cuenca Pallasca, Ancash, Perú. La metodología es tipo básica, descriptiva. población muestra toda el área en estudio. Los principales resultados muestr...

The study of geographical systems as graphs, and networks has gained significant momentum in the academic literature as these systems possess measurable and relevant network properties. Crowd-based sources of data such as OpenStreetMaps (OSM) have created a wealth of worldwide geographic information including on transportation systems (e.g., road networks). In this work, we offer a Geographic I...
