Crowdsourcing Landscape Change

Hampshire County Council, on behalf of the Hampshire Hub Partnership, is collaborating with Remote Sensing Applications Consultants Ltd (RSAC) and the University of Portsmouth (UoP) on the Crowdsourcing Landscape Change project, co-funded by Innovate UK (formerly the Technology Strategy Board), to develop an innovative solution for the extraction of information from archived aerial photography using crowdsourcing via an online platform.

The archives of aerial photography held by Hampshire’s local authorities contain an abundance of historical information. However, because of the volume and complexity of the data and the lack of resources for their systematic analysis, their value has not been fully realised. In the Crowdsourcing Landscape Change project, RSAC Ltd will apply its expertise in land cover change mapping to the adaptation of crowdsourcing technology pioneered by UoP for the development of a pre-commercial service demonstrator aimed at creating new insight from aerial photography by mapping changes in the landscape between image dates.

The results have the potential to improve a range of environmental management and protection processes. There is more information about the project in a presentation by Tim Pearson of Remote Sensing Applications Consultants.

  1. […] Another example project is Landscape Watch Hampshire, which is sharing a rather complex type of data: aerial photography from 2005 and 2013. To compare these with the aim of documenting changes to the landscape and its use really requires humans, so the plan of Hampshire’s collaboration with the University of Portsmouth and Remote Sensing Applications Consultants Ltd is to crowdsource analytical input from the public. This is explained in more detail at […]
