Recent developments of 3D technologies and tools have increased availability and relevance of 3D data (from 3D points to complete city models) in the geospatial and geo-information domains. Neverthele...
With the fast growth of internet-based sharing mechanism and OpenGIS technology, users nowadays enjoy the luxury to quickly locate and access a variety of geospatial data for the tasks at hands. While...
Many older maps were created using reference coordinate systems which are no longer available, either because no information to a datum was taken in the first place or the reference system is forgotte...
Coastal change analysis, particularly of the variation in shorelines and blufflines, is critical for coastal disaster mitigation, environmental protection, resource management, and coastal development...
An Updating Method of Geospatial Data Based on Traffic Flow Analysis     Network GIS   Traffic Flow  Data Updating       font style='font-size:12px;'> 2015/10/12
The paper proposes a new kind of objected-oriented method of updating geospatial data, that is different from the previous “bottom up” or “top down” updating methods. Through weighted directed graph...
In this paper we describe our efforts to develop a system that generates interactive Virtual Environment at the client PCs, by rendering geo-spatial data that is stored at a remote server. The end-us...
A large amount of earth science data, collected by Geological Survey of India since its inception in 1851, has been brought to electronic media for storage, quick access, retrieval and analysis in GI...
Transportation agency representatives provided case-study input in an investigation of how geospatial data libraries are used for managing remote sensing data and other geospatial data for transport...
Wetlands regulate the flow of water and play a key role in risk management of extreme flooding and drought. In Colombia, wetland conservation has been a priority for the government. However, there i...
An earthquake occurred at Van City on 23 October 2011 at 13:41 local time. The magnitude, moment magnitude and depth of earthquake were respectively MI:6.7, Mw:7.0 and 19.07 km. Van city centre and it...
Recent developments in spatial data infrastructures have enabled real time GIS analysis and visualization using open input data sources and service interfaces. In this study we present a new concept w...
The aim of this research is to design and implement a knowledge discovery system that facilitates, using a web 2.0 collaborative approach, the identification of new risks of geospatial data misuse b...
Road and rail networks are essential components of national infrastructures, underpinning the economy, and facilitating the mobility of goods and the human workforce. Earthwork slopes such as cuttings...
A new geospatial data sharing/overlay system, CEReS Gaia, has developed. The purpose of the system development is to promote land surface environmental studies. The system has developed to meet the ...
In the past decades, many geospatial databases have been established at national, regional and municipal levels over the world. Nowadays, it has been widely recognized that how to update these estab...
