  • Geographical location of buildings. Buildings are any structure permanently constructed or erected on its site, covered facilities, usable for the protection of humans, animals, things or the production of economic goods.

  • Hydrographic elements, including river basins and sub-basins.

  • The dataset of the ITHACA (ITaly HAzard from CApable faults) project, is built on a faults database, where is stored all the information available about the Italian active tectonic structures. It takes in account the active tectonic processes that could be able to generate natural hazard. In the database are archived all the faults that can produce surface deformations. The main attribute are: the type of kinematic, the type of fault and the geoenviromental evidence.

  • The centralised data storage facilities of the Geological Survey of Finland (GTK) contain altogether 28857 deep drill holes and boreholes to the bedrock. The drillings began in the 1920's and they still continue. The drilling data has been collected to databases since in 1989. The information of drillings which are older than this has been digitised when necessary. The deep drill holes of the bedrock are a spatial data in which the rock sample has been taken from a certain location by drilling. The data contains the information which is related to this sample site and to the core sample. The azimuth, dip and length of the drill hole vary according to the geological environment of the area. The drilling is performed based on the drilling plan drawn up by a geologist. The geologist supervises the drilling site and the realization of the plan and observes and records the information to the database. The following information is saved to the database: the information related to the positioning and location of the drilling, the information about the drilling organization, the information of the storage place of the core sample, the dip of the drill hole, the lithological information of the sample, cutting angle of the structures, the ore minerals and their appearance in the sample, mineral alteration, structure and texture, stratigraphy, core loss, analysed sample intervals and the geochemical analysis results, physical and petrophysical laboratory measurements, drill hole soundings and thin sections. In the deep drill holes the azimuth is determinated in degrees. In the full circle there are 360°. The cardinal azimuth is set to be North (000° or 360°). The hole azimuth is decided by the geologist assisted by geophysical background information and geophysicist. The objective is to get a representative sample of the bedrock units. Hole dip refers to the angle between a horizontal direction and a drilling. The hole dip in the databases of GTK is represented in degrees (°). The dip of the vertical hole is 90°. In horizontal hole the dip is 0°. In that case the drilling has been performed either in a mine or in a quarry or the sample is continuous gouge sample sawed from the bedrock. With respect to the horizontal surface the dip of the drill hole is negative upwards. For example, when a dip is -45° the hole has been drilled in underground mine in the angle of 45 degrees to upwards. The dip of the hole to be drilled is decided by the geologist assisted by geophysical background information and geophysicist. The dip can be presented also as grads. This unit has been used mainly by mining companies. The length of the drilled hole in the databases of the GTK is represented in metres (m). In addition to the drilling plan, the capacity of the drilling machine and the quality of the bedrock affect the length of the drill hole. In the shattered bedrock the hole can be jammed before the objective length. The lengths of the drilled holes vary from 1 metre to 2,5 kilometres. Petrophysical laboratory measurements have been made from the drill core since about the year 1965. Since the year 1963 petrological and ore analyses have been made from the selected core samples. The use of analyses was established and increased at the end of the 1980's with the development of analysis methods. During the present the geochemical analyses are an essential part of the drilling project and are done from all the bore holes, with few exceptions. The type samples representing the lithological units of the area and the sample intervals significant to exploration are selected for analyses. The deep drill holes have been made by the following programmes of the GTK: ore exploration, rock and mineral aggregate studies, natural stone investigations, bedrock mapping and urban mapping. In addition to these, the deep drill holes have been made among others by Outokumpu, Rautaruukki and Lapin Malmi and by the cooperation projects drawn by the universities. The data sets from different sources are not commensurable and information on the quality of the data is partly lacking. The data have been digitised when necessary and a part of the drilling information is still in the paper based archives.

  • While Royal Mail (RM) allocate and maintain postcodes for the purposes of delivering mail, National Records of Scotland (NRS) create and maintain digital postcode geographies to support the production of high quality statistics. This dataset provides the geometric grid references (or centroids) of postcode districts which are the next hierarchical level above the postcode sector, represented by the outward code (first part of a postcode). For example, if the individual postcode is EH12 7TB, then the district of that postcode is EH12. NRS publish these grid references twice a year as part of the Scottish Postcode Directory (SPD) which should be considered the definitive source for postcode geographies in Scotland.

  • '''Short description:''' The current version of the TOPAZ system - TOPAZ4b - is nearly identical to the real-time forecast system run at MET Norway. It uses a recent version of the Hybrid Coordinate Ocean Model (HYCOM) developed at University of Miami (Bleck 2002). HYCOM is coupled to a sea ice model; ice thermodynamics are described in Drange and Simonsen (1996) and the elastic-viscous-plastic rheology in Hunke and Dukowicz (1997). The model's native grid covers the Arctic and North Atlantic Oceans, has fairly homogeneous horizontal spacing (between 11 and 16 km). 50 hybrid layers are used in the vertical (z-isopycnal), more than the TOPAZ4 system (28 layers). TOPAZ4b uses the Deterministic version of the Ensemble Kalman filter (DEnKF; Sakov and Oke 2008) to assimilate remotely sensed as well as temperature and salinity profiles. The output is interpolated onto standard grids and depths. Daily values are provided for the surface variables. Data assimilation, including the 100-member ensemble production, is performed weekly.

  • While Royal Mail (RM) allocate and maintain postcodes for the purposes of delivering mail, National Records of Scotland (NRS) create and maintain digital postcode geographies to support the production of high quality statistics. This dataset provides the digital boundaries of postcode sectors which are the next hierarchical level above the individual postcode, represented by the outward code plus the first character of the inward code. For example, if the individual postcode is EH12 7TB, then the sector of that postcode is EH12 7. NRS publish these boundaries twice a year as part of the Scottish Postcode Directory (SPD) which should be considered the definitive source for postcode geographies in Scotland.

  • GE.Bedrock 1:50 000 - 1:250 000 is a simplified and transformed version of SGU's bedrock information in the scale of 1:50 000 - 1:250 0000 and conforms to the Inspire dataspecification for Geology through encoding according to GeoSciML 3.2

  • Location of properties based on the adress identifiers, usually the street name, house number and postcode.
