The ASTER Global Digital Elevation Model Version 3 (GDEM v3) was evaluated over the conterminous United States in a manner similar to the validation conducted for the original GDEM Version 1 (v1) in 2...
In 2016, the US/Japan ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) project released Version 3 of the Global DEM (GDEM). This 30 m DEM covers the earth’s surface from 82...
Quality evaluation and control has become the main concern of VGI. In this paper, trust is used as a proxy of VGI quality, a version-similarity based trust degree computation model for crowdsourcing g...
We present a new approach to the old problem of adding global mutable state to purely functional languages. Our idea is to extend the language with “witnesses,” which is based on an arguably more prag...
Global Map is global digital framework geographic information. 179 countries and regions participate with the project to develop the Global Map and over 96 % of whole land areas of the earth are inclu...
Temporal Geographic Information System (TGIS), which aims to collect, manage and analyze dynamic geographic phenomena, is a hot scientific research field. The all-important task of developing a TGIS i...
In this paper, a version-difference spatial-temporal data model is proposed. The main research interest centers on spatial-temporal data storage and manipulation. This model uses the terms version and...
A SEMANTICS FOR VERSION QUERIES IN GIS DATABASES.
This paper identi es ten distinct ways in which to charac-terize the concepts of both `polarization' and `diversity'. Although these two concept clusters are not typically associated, both are descrip...
On October 17, 2011, NASA and the Ministry of Economy, Trade and Industry (METI) of Japan released the second version of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Gl...
The ASTER Global Digital Elevation Model Version 2 (GDEM v2) was evaluated over the conterminous United States in a manner similar to the validation conducted for the original GDEM Version 1 (v1) in...
The Global Mapping Project aims to develop basic geospatial information of the whole land area of the globe, named Global Map, through the cooperation of National Mapping Organizations (NMOs) around...
The stress singularity exists at the crack tip and the weld toe. The stress singularities are expressed by a term of −1/2 power of distance r from the singular point for the crack tip, and ͨ...
A new version of an experimental set-up for examination of linear contraction and shrinkage stresses progress of metals and alloys during– and after solidification has been described. By new method th...
The numerical solution of the thermal part of a coupled thermo-mechanical contact problem is presented. The hp-version finite element method is used for the discretization of the temperature field in ...
