Crowdsourcing, Citizen Science or Volunteered Geographic Information? The Current State of Crowdsourced Geographic Information
TLDR
Citizens are increasingly becoming an important source of geographic information, sometimes entering domains that had until recently been the exclusive realm of authoritative agencies. Expand
Assessing Crowdsourced POI Quality: Combining Methods Based on Reference Data, History, and Spatial Relations
TLDR
We propose two types of approaches: (1) use the intrinsic characteristics of the crowdsourcing datasets; or (2) evaluate crowdsourced Points of Interest (POIs) using external datasets (i.e., authoritative reference or other crowdsourced datasets). Expand
Towards a Protocol for the Collection of VGI Vector Data
TLDR
A protocol for the collection of vector data in Volunteered Geographic Information (VGI) projects is proposed. Expand
Moving and Calling: Mobile Phone Data Quality Measurements and Spatiotemporal Uncertainty in Human Mobility Studies
TLDR
In the past few years, mobile network data are considered as a useful complementary source of information for human mobility research. Expand
Data Matching - a Matter of Belief
TLDR
In this paper, one approach of matching geographic data bearing on the belief theory is presented. Expand
The Scale of VGI in Map Production: A Perspective on European National Mapping Agencies
TLDR
The perspective of European National Mapping Agencies on the role of citizen sensing in map production was explored. Expand
Extracting Semantics of Individual Places from Movement Data by Analyzing Temporal Patterns of Visits
TLDR
We develop an intelligent system that learns how to classify personal places and trips while a human analyst visually analyzes and semantically annotates selected subsets of movement data. Expand
Looking at spatiotemporal city dynamics through mobile phone lenses
TLDR
In this paper we propose to study urban mobility by using mobile phone data. Expand
Knowledge formalization for vector data matching using belief theory
TLDR
In this paper a multi-criteria data matching approach allowing the automatic definition of links between identical features is proposed. Expand
Chatty Mobiles:Individual mobility and communication patterns
TLDR
We propose to estimate the correla-tion between the user’s communication and mobility in order to better assess the bias of frequency based sampling. Expand
