Technological advancement is the key driver for economic growth and sustainable development. Geospatial Technologies applications and tools available today are being used for improved performance of a...
Currently, geospatial datasets are produced in various models and formats in accordance with the spatial scale of the real world such as ground/ surface/underground or indoor/outdoor. The location-bas...
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...
One viewpoint of current and future IT systems holds that there is an increase in the scale and velocity at which data are acquired and analysed from heterogeneous, dynamic sources. In the earth obser...
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...
GML-an Open-Standard Geospatial Data Format     GML  Internet  Spatial Data Sharing  Geometry  Visualization       font style='font-size:12px;'> 2015/12/18
In the last three decades, dozens of GIS data formats have been developed for encoding geographic information. Most were specified formats to particular vendor’s GIS software. A few were open standard...
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...
In this paper, a framework is proposed to assess the quality of urban geospatial data using image information. An important aspect is the emphasis on accuracy and reliability of the system. The qualit...
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...
This paper introduces the author's work on the compression of vector geospatial data intended for transport on the Internet. WebGIS vector data format is shifting to ASCII code such as XML. In some ap...
