All Wales Phase 1 Terrestrial - Scans

This is a spatial dataset of raster images of the hand-coloured Phase 1 Survey 5x5 km square 1:10,000 Ordnance Survey maps. The original maps ('master maps') are lodged in the National Library of Wales. The original field surveys were carried out as part of a national habitat survey programme required to implement conservation at a local level. An all-Wales electronic dataset was created for the generation of national statistics on habitat coverage. The dataset was subsequently imported into a GIS to enable its disaggregation into various different geographical regions within Wales.

Lineage: The field survey spanned from 1987 to 1997. Closely co-ordinated teams of surveyors carried out field recording of habitats onto 1:10,000 scale maps. The minimum size of habitat patch recorded lies predominantly within the range 0.1-0.25 ha, although smaller areas were mapped in the lowlands. Methods followed the Handbook for Phase 1 Habitat Survey with some minor modifications adopted for use in Wales (Howe E.A. and Blackstock T.H. (1991) Supplementary Notes for Phase I Survey in Wales. CCW, Bangor). All field mapping was carried out by trained and closely co-ordinated teams of surveyors. A study of survey reliability was conducted during the lowland phase (Kerry, Rimes, Smith, Williams. 1994. An Assessment of Errors in Phase I Habitat Survey in Wales. Bangor: Countryside Council for Wales, Report No. 94/4/1). It showed the field mapping to be 83% repeatable (Stevens, Blackstock, Howe, Stevens. 2004. Repeatability of Phase 1 habitat survey. J. Environ. Manage. 73, 53-59). The electronic data have undergone a series of checks for accuracy both by the contractor and subsequently within CCW.
