Digitised version of aeromagnetic survey records of Great Britain comprising a record for each digitised point, supported by survey and 'ends and bends' based line indexes. Original records include flight line records, worksheets, contour sheets and air photos provided by contractors at completion of each survey. Worksheets digitised by BGS during 1980's Smith and Royles 1989.

Land Cover Scotland (LCS) 1988 was the first ever national (air-photo) census of land cover in Scotland to describe the principal features and characteristics of the countryside. It was produced by The Macaulay Land Use Research Institute (now the James Hutton Institute) on behalf of Scottish Government to assist in the development and monitoring of policies affecting the state of the Scottish countryside. It was intended that the 1988 LCS be used as a baseline for monitoring change. The classification system allows for 126 land cover types to be identified as point, line or area features. An important aspect of the classification system is that it allows for mosaics of the land cover types to be identified, where the pattern of cover types was so complex that individual types could not, at the selected interpretation scale, be separated. Over 1300 mosaics are identified in the LCS dataset.

Guyadiv is a network of permanent forest plots installed in French Guiana. The site of Crique Cacao is composed of two plots (20x530m and 20x200m). A complete inventory has been made in 1987, 662 trees with dbh >= 10cm have been inventoried. In the first plot, 433 species have been determined and 193 in the second plot. The percentages of trees identified to the species level are respectively 93.7% and 96.5% for each plot. We only have the point coordinates and not the precise demarcation of the sample plots. In order to calculate the bounding box for these plots, we have expanded the point location 500 meters in each direction.

O sistema de classificação da Capacidade de Uso do Solo apresentado, é baseado na USDA System of Land Use Classification ao qual introduziram pequenas alterações de modo a melhor adaptar à realidade Açoriana.

Aire parcellaire délimitée de l'AOP "BORDEAUX" En application des réglementations européenne et nationale, une aire géographique est définie dans les cahiers des charges des produits sous signe d'origine. Le terme "aire parcellaire délimitée" désigne une délimitation qui repose sur les limites administratives du cadastre (les parcelles) et dont le maillage suffisamment fin permet de tenir compte de variations très localisées des éléments du milieu physique. Elle correspond à l'aire de production de la matière première. Elle est incluse dans l'aire géographique.
