Development of an agricultural land use spatial dataset to aid agricultural/environmental spatial modelling - NT2206

In the assessment of the interaction between agricultural practice and the environment, a mask which delineates areas of agricultural use from those of non-agricultural use would aid interpretation of both satellite imagery and census data. This project will aim to develop an agricultural land use spatial dataset to aid agricultural and environmental modelling and assessment. The study will be composed of 4 specific objectives outlined as follows, together with ways in which they might be achieved: 1. Identification of available primary and secondary data sources, their extents, completeness, costs and licensing arrangements. Primary data sources will include the DETR Urban Land Use map, the Digitised Map of Common Land and also the extent of forests where possible. Secondary data sources will include maps of major roads and the location of airfields etc. New data sources will also be investigated; 2. Integration of data into GIS of England and Wales and estimation of non-agricultural land use at 1 km resolution. Data will be used to generate estimates of the land area covered by urban land, common land etc. For line and point data it will be necessary to estimate the area involved; 3. Calibration and validation of the dataset. The accuracy of the dataset will be evaluated using ground truth data from large Nitrate Sensitive Areas, of which the extent of agricultural land for several has been accurately mapped; and 4. Preparation of the final dataset and report. The final dataset will be made available for integration into MAFF’s Nitrate policy support model, and for use in conjunction with Landcover 2000.
