Volunteered Geographic Information (VGI)Volunteered Geographic Information (VGI)

• The term “volunteered geographic information” (VGI) refers to GI which is created in collaboration by users who usually don't have special skills in handling spatial data. This makes it difficult to incorporate such GI in applications depending on high quality data.

• Volunteered Geographic Information (VGI) has the potential to bea significant source of geographers’ understanding of the surface of the Earth’’- (Michael Goodchild, 2007). Goodchild has also termed this phenomenon as user-generated content.

• User-generated geospatial content through the web is part of Geospatial components of the Web 2.0 and, an example of Neogeography.

Socio-EconomicalAspects

What Neogeography is???What Neogeography is???

• Neogeography is telling the story of a place in one’s own way. The tools can be tagging, blogging, photo sharing and script writing about the geography of a place. It is the new way of thinking about geography.

• Adding and describing a newly discovered place on the map, telling the changes of the map, landuse, Road network and structure of an area.

• It is followed by the daily update of the map, it is a new way of sharing one’s experience of vacation in a new and exciting place. It is the easiest way to to create maps and of sharing the locations of a one’s interest and history.

What is Web 2.0???What is Web 2.0???

• According to Wikipedia Web 2.0 is a trend in World Wide Web technology, and web design, a second generation of web-based communities and hosted services such as social-networking sites, wikis, blogs, and folksonomies, which aim to facilitate creativity, information sharing, collaboration, and sharing among users.

• It is almost defined as the new era of the World Wide Web.

• The term became notable after the first O'Reilly Media Web 2.0 conference in 2004. The term suggests a new version of the World Wide Web, it does not refer to an update to any technical specifications, but to changes in the ways software developers and end-users use webs.

Business Model of Web 2.0Business Model of Web 2.0• Web 2.0 introduces business model through creating places

online where people would like to come together to share what they think, see and do.

• The most hosting sites of User-Created Content (UCC) started their steps with no business plans but the increasing demand and the increasing number of hits on the sites insisted them to think again and they started earning revenue.

• The website 2.0 still offer free access to their services. Theireconomy is based on the ability to enhance exchanges and activities that develop on the site to generate revenue around this free service.

• According to Beuscart, Dacheux and Kevin there can be four forms of monetizatin of Web 2.0. They are as follows;AdvertisingThe Freemium Principle (Free+Premium)Market Place.Collection of resources based on giving and Volunteering

Main Research ObjectivesMain Research Objectives

• Main ObjectiveThe Main Objective of this study aims to givean outline for achieving socio-economicbenefits of Volunteered GoegraphicInformation (VGI).

• Specific ObjectiveTo Present VGI as a new Business Model.To Provide a socio-economical evaluationframework for the evaluation of VGI.

Methodology to adopt ObjectivesMethodology to adopt Objectives

Ethical BackgroundEthical Background

• Present mapping world is looking forward to bemore faithful to reality coping with the development of 3D maps.

• Mobile mapping and remote sensing are inherently prone to human errors, needs more revisit rates and cover no story about places.

• In this sense, neogeography can be consideredas an up- to- date mapping technic in comparison to mobile mapping and remotesensing.

Political and Social AcceptancePolitical and Social Acceptance

• Increasing new interest by the tax authorities.

• The Governments are having off-line economicgains.(OECD, 2007)

• Virtual transactions but treated as underground economy (OECD, 2007).

• Building a digital Society through Web 2.0. The Facebook community can be an example of digital neighbourhood.

ConclusionConclusion

• Neogeography with VGI has the potential to savethousands of lives and billions of Dollars a year in the US. (Wilson, C.2007)

• The users are making the contents freely, so the products being cheap.

• Increase for consumer deals in big sale and the bigsale decrease the cost of products. A long tailgraphics is created in the market.

• VGI is supposed to bring a positive effect in mapping science and on the market of Geospatialdatabase which will be positive for both the consumers and suppliers.
