VALIDATION OF THE ASTER GLOBAL DIGITAL ELEVATION MODEL VERSION 3 OVER THE CONTERMINOUS UNITED STATES
Accuracy DEM/DTM Comparison Geodesy Global-Environmental-Databases Land Cover Mapping Satellite
2016/11/8
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...
A VERSION-SIMILARITY BASED TRUST DEGREE COMPUTATION MODEL FOR CROWDSOURCING GEOGRAPHIC DATA
Crowdsourcing Geographic Data Trust Degree Reputation
2016/7/8
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...
