| data_date | Continuous mapping 1930's-1970's |
| description | Scottish soils 1:25 000 polygon vector data set. Produced by MLURI, UK. 1994-96. Extent limited to lowland and agricultural areas with some exceptions. |
| raster_vector | vector |
| filename | Filenaming convention is based on Ordnance Survey tile identification codes. For example: nj74soil.e00 for 10X10km tiles; NTSE.e00 for 50X50km tiles. |
| software | Digitising using PC based package TYDIG (module of SPANS GIS package from Tydac technologies), followed by transfer to ARC/INFO Version 7. Output as ARC/INFO Export files. |
| formats | ARC export and ARC generate |
| operating_system | PC MS-DOS 5 |

| attributes | 3 attribute codes: 'code' - 7 digit number (combination of series and phase codes) 'series' - 4 or 5 digit number (first 2 or 3 digits indicate association codes, remaining 2 are series codes) 'phase' - additional information relating to soil characteristics |
| methods | Forms a hierarchical classification: Association: groups soils formed similar parent materials Series: different major soil subgroups within associations Association and Series both named after localities and converted to numeric codes (see above) Phase: specific features of interest for a limited number of soil series |
| other | MLURI holds a soils attribute data base within ORACLE RDBMS listing information on the soils, soil profiles etc. with codes linked to the polygon vector soils map data. The 1: 25 000 scale soils data was digitised from clean copy, published and unpublished, uncoloured soils maps which were used in the compilation of the 1:63 360 colour map series. |
