This article is about mapping the veterans’ inscriptions from Upper Moesia using ArcGIS software. How can this be done and toward what aims? By applying GIS algorithms to these datasets, we make various maps queries that allow us discuss distribution spatiality many different angles. Such an experiment provided possibility of a better visualization data in geographic context allowed identify sp...

In cable trench construction, one of the tasks for engineers is to select a suitable route to minimize construction cost and obstructions. This paper discusses the development of a Geographic Information Systems (GIS)-based Customized system to automate the process of optimum shortest path finding for routing of underground power supply cable between any two substations. It combines the spatial...

Landmarks provide the most predominant navigation cue for pedestrian navigation. Very few navigation data models in the geographical information science and transportation communities support modeling of landmarks and use of landmark-based route instructions for pedestrian navigation services. This article proposes a landmark-based pedestrian navigation data model to fill this gap. This data mo...

This paper discusses the establishment, management and application of remote sensing image database. A systematical structure for remote sensing image database is presented and analyzed. This architecture is based on web service technology, rather than traditional Browser/Server or Client/Server model. To process and publish mass remote sensing images on the web, appropriate system framework an...

The Soil and Water Assessment Tool (SWAT) is a widely used hydrological model that produces several useful outputs (e.g. evapotranspiration, soil moisture, aquifer recharge, river discharge) as text files. Currently, visualizing and publishing SWAT outputs as geospatial data requires a lot of time and repetitive processing steps. Moreover, data used and produced are often not interoperable and ...

The knowledge of the surface topography has a major importance in the field of Earth sciences. It is essential in any discipline concerned with process modeling like hydrology, climatology, geomorphology and ecology. The present study utilized Environmental Systems Research Institute’s (ESRI) ArcGIS 9.3 (with the spatial analyst extension) software, remote sensing data ( DEM and Digital Aerial ...

The purpose of this study is to map wetlands using multi-polarimetric and polarimetric analysis of ALOS Palsar data in coastal North Carolina. Radar sensor offers reliable acquisition of wetlands which are mandated, by Congress, to be mapped every ten years. Radar data products were generated using Wishart supervised (HH-HVVV) and Wishart unsupervised (entropy and dominant scattering mechanism)...

The global management of complex urban environments require flexible Information Systems able of adapting to different needs of private and institutional agents related to preservation and sustainability of Cultural Heritage. Heterogeneity of formats and sources makes difficult the transfer of digital information, which is increased by nontextual support. 3D models provide a support enabling re...
