The sixth of a series of papers as part of a special issue of the Open Access Journal Future Internet on the theme “Internet and Landscapes“, as edited by the ISPRS Working II/6 on Geographical Visualization and Virtual Reality (Chris Pettit and Arzu Coltekin) has now been published by  Subhash Sharma, Chris Pettit, Ian Bishop, Pang Chan and Falak Sheth. This paper examines how geo-visualisation tools can provide useful participatory planning support in addressing issues of land productivity and sustainability. The research team have developed an online landscape library, which has been integrated with a suite of geo-visualisation tools including a GIS based Landscape Constructor tool, a modified version of a 3D game engine SIEVE (Spatial Information Exploration and Visualisation Environment) and an interactive touch table display. The paper includes some preliminary evaluation of the tools and outlines some further research directions.
