Volunteered Geographic Information (VGI) in Spatial Data Infrastructure (SDI) Continuum

Spatial data infrastructure (SDI) is a system that supports the management and use of geospatial related resources. It involves creation maintenance network organizations, people, technology enables sharing across sectors stakeholders. In recent years, growth increasing reliance on it by various has led to emergence new trends in SDI, such as cloud computing big analytics, integration with other types data, emphasis open interoperability. Volunteered geographic information (VGI) refers collected contributed individuals or groups, rather than traditional sources using application web 2.0 location based applications, social media, mobile devices say citizens censors. Crowdsourcing generation concept VGI changed SDI having one way relationship producers users user driven where create diverse, high quality (spatial, temporal, attribute) also interoperable, transparently, world widely free cost. Various authors have discussed about digital point outs possibility starting form Global GIS platform, Data Spaces, System Systems (SoS), Geoverse, Digital Earth, Twin, Virtual Geographic Environment (VGEs). However, there exists multiple challenges quality, structure, differentiation, copyright, confidentiality privacy, but proper cooperation partnerships, policy legal arrangements, standard developments, financial inter/intra communication added advantages 3.0, Ecosystem containing SoS possible. Hence, present future this continuum.
