SCALING-UP IN HYDROLOGY USING REMOTE-SENSING - SUMMARY OF A WORKSHOP

This paper summarises the presentations and recommendations of an inte rnational Workshop on 'Scaling up in hydrology using remote sensing' w hich 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 propagati on of errors in remote sensing through models to their outputs. To fac ilitate these investigations the Workshop highlighted these essential requirements-to make data sets more readily available and user friendl y, develop formal programmes to compare algorithms and earmark funds s pecifically for these analysis programmes.
