We are currently working with several Maori iwi in New Zealand to improve their GIS capabilities and integrate spatial knowledge in their decision-making processes. The main aim of this work is enabling the iwi to create and manage their own GIS projects and use the results to enhance their day to day operations and long-term planning. In this pilot study on land use improvement with GIS and RS we created a spatial model to find the best land uses for a given land block and then integrated the results with profit forecasts in order to provide the landowners with a better understanding of the land capability. We used high resolution data captured with drones as well as freely available spatial datasets that we processed, reclassified, weighted and combined using ESRI ArcGIS software. The result is a series of land unit polygons, each representing a unique combination of possible land uses and relative forecast profit. This combined spatial and economic information provides a comprehensive understanding of the potential of a block of land. The modelling process is simple, flexible, clear to understand and easy to replicate, but more importantly it can be effectively used to make informed land management decisions.
