This project will aim to undertake a census survey of the land cover and widespread broad habitats of Britain at the turn of the Millennium, and to calibrate and validate results against ground reference data. Satellite imagery and automated image processing techniques will be applied, in order to achieve a classification accuracy of 90% for approximately 18 target land cover types. Target classes will be further divided into subclasses (at a lesser overall accuracy). Geographically referenced data outputs on land cover characteristics, tailored to the needs of Consortium members will be produced and made available, under licence. Satellite-derived classifications against ground reference data will be calibrated and validated, and results of the correspondence analyses will be published along with a guide to their interpretation. The survey data will inform MAFF policy development and will provide data on the state of the environment, wildlife and sustainable development. Uses of the land cover map will include programmes which take stock, assess changes, help understand environmental relationships, and predict and manage change.
