Scaling up in hydrology using remote sensing: Summary of a Workshop

This paper summarises the presentations and recommendations of an International Workshop on 'Scaling up in hydrology using remote sensing' which was held at the Institute of Hydrology in June 1996. The Workshop highlighted considerable gaps in our knowledge of scaling issues and strongly recommended further analysis of existing data sets to assess the accuracy of remotely-sensed algorithms and assessment of propagation of errors in remote sensing through models to their outputs. To facilitate these investigations the Workshop highlighted these essential requirements to make data sets more readily available and user friendly, develop formal programmes to compare algorithms and earmark funds specifically for these analysis programmes.
