<h2>Special Issue "Volunteered Geographic Information" of the<a

<meta http-equiv="content-type" content="text/html; charset=utf-8">
<p> Parallel to the advent of Web 2.0 technologies, volunteered
geographic information (VGI) has emerged as a novel form of
user-generated content, which involves both active forms of
contribution such as online mapping or the explicit
georeferencing of various media as well as the passive
collection of data via the user’s location-enabled smartphone.
Due to an abundance of corresponding VGI platforms and Location
Based Social Networks (LBSN), there are now massive datasets,
which are freely available and have the potential to complement,
update or even replace data obtained from traditional sources
such as commercial vendors, public authorities or mapping
agencies. However, due to inherent characteristics of VGI, which
mostly result from a lack of formal specifications, exploiting
its full potential is still challenging and in need of issues
such as quality assessment, data integration or standardization
to be addressed. </p>
<p>Active research is ongoing that addresses many of these issues
including initiatives such as COST Action networks TD1202
(Mapping and Citizen Sensor) and IC1203 (ENERGIC), which bring
together researchers across the EU to address many pressing
issues related to VGI. The European Citizen Science Association
(ECSA) and its counterpart in the USA (Citizen Science
Association) are also strong alliances of public and private
organizations involved in research of relevance to VGI, among
many others in a growing field of interest.</p>

Issue in the ISPRS International Journal of Geo-Information</a>
is dedicated to explore current trends with regards to the
technological, methodological, conceptual and social dimensions
of VGI. <strong><a moz-do-not-send="true"

call for original papers</a></strong>, equally from both
within the COST Actions, citizen science associations and from
researchers around the world, which focus on all topics
involving the collection, processing, analysis and general use
of VGI.<br>
