Overview: Information about land cover, land use and the change over time is used for a wide range of applications such as nature protection and biodiversity, forest and water management, urban and transport planning, natural hazard prevention and mitigation, agricultural policies and monitoring climate change. High quality spatially explicit information on land cover change is an essential input variable to land use change modelling, which is increasingly being used to better understand the potential impact of certain policies. The overall aim of CrowdLand is to test and demonstrate the potential of using crowdsourcing for land-use related data collection. The project will build upon the success of the Geo-Wiki experience but will move from online data collection via Google Earth or Bing maps to direct in-situ data collection on the ground via smartphones (delivering information on land-use with location, orientation and tilt). A key element will be the idea of a Mobile Guided Point and Direction Finder (MGPDF). This functionality will be a generic feature of the mobile applications built as part of this project in order to help ordinary people to easily find points that are located off-road. The project will discover which incentives are the most appropriate for land-use data collection for different user groups and in different environments, e.g. using the M-pesa system in Kenya and what is the minimum payment needed in order to get citizens involved in data collection. Also, CrowdLand will identify how people are reached (e.g. using ordinary text messaging - SMS) in remote places. Data collection will be carried out by citizen observers and local experts using GPS enabled cameras, smartphones and electronic notebooks. Since information on land cover, land use and change outside of Europe is rarely available in Kenya was selected to case study this project.
IIASA Research: IIASA will determine the feasibility of complementing LUCAS sampling with crowdsourced information via different incentives in Europe. The potential of using mobile money via small payments and other incentives to citizens to replicate LUCAS in developing countries will be examined. The use of mobile phone-based data collection kit (mainly picture-based) given to organizations to monitor success of their programs and actions while at the same time collecting data on global land-use will be investigated. Crowdsourced land-use data in different environments and in different thematic areas using authoritative sources will be assessed. IIASA will also develop new approaches of using point data sources for map data fusion and hybrid map generation, building upon expertise already developed.
