BIG GEO DATA MANAGEMENT: AN EXPLORATION WITH SOCIAL MEDIA AND TELECOMMUNICATIONS OPEN DATA
User-generated communication traffic Open Data Big Geo Data
2016/7/8
The term Big Data has been recently used to define big, highly varied, complex data sets, which are created and updated at a high speed and require faster processing, namely, a reduced time to filter ...
Using social media for disaster emergency management
social media Sina-Weibo emergency information
2016/7/8
Social media have become a universal phenomenon in our society (Wang et al., 2012). As a new data source, social media have been widely used in knowledge discovery in fields related to health (Jackson...
A method for studying the development pattern of urban commercial service facilities based on customer reviews from social media
commercial service facility analysis based on road network constraints quantitative evaluation of urban planning
2016/7/8
Urbanization is one of the most important human social activities in the 21st century (Chaolin et al., 2012). With an increasing number of people visiting cities, the provision of adequate urban servi...
SPATIAL-TEMPORAL ANALYSIS OF SOCIAL MEDIA DATA RELATED TO NEPAL EARTHQUAKE 2015
Spatial Temporal Geoweb
2016/7/8
Social Medias these days have become the instant communication platform to share anything; from personal feelings to the matter of public concern, these are the easiest and aphoristic way to deliver i...
Using geo-targeted social media data to detect outdoor air pollution
Social media Outdoor air pollution Spatiotemporal relationship
2016/7/8
Outdoor air pollution has become a more and more serious issue over recent years (He, 2014). Urban air quality is measured at air monitoring stations. Building air monitoring stations requires land, i...
Automated calibration technique for photogrammetric system based on a multi-media projector and a CCD camera
Photogrammetry Calibration Accuracy Multi-media projector Non-contact measurements
2015/8/25
Recently multi-media projectors became commercially available for using in 3D reconstruction application. They have a number of features which make them attractive for using in photogrammetric applica...
CAMERA CONSTANT IN THE CASE OF TWO MEDIA PHOTOGRAMMETRY
Two media photogrammetry Calibration Camera constant Refraction
2015/4/23
Refraction is the main cause of geometric distortions in the case of two media photogrammetry. However, this effect cannot be compensated and corrected by a suitable camera calibration procedure (Geor...

2015/2/4
The effects of horizontal density gradient and nonlinear drag offered by the solid particles on turbulent flow through
geological media are analysed analytically in the presence of a vertical gravita...
EXPLOITING THE MULTI VIEW GEOMETRY FOR AUTOMATIC SURFACES RECONSTRUCTION USING FEATURE BASED MATCHING IN MULTI MEDIA PHOTOGRAMMETRY
Matching Algorithm Multi View Geometry Multi Media Photogrammetry Surface Reconstruction
2015/1/6
In this paper we present a new method of a feature based matching algorithm for a 3D surface reconstruction exploiting the multiview geometry. The matching algorithm conceptually allows parallel proce...
