Observation site (e.g. well) used to watch for the advent of an anticipated condition, generally undesirable, such as the advance of the salt-water front in a coastal area where salt-water encroachment is occurring, or the movement of a pollutant injected into a disposal well. IGH0806 The feature hosting the site, e.g. a well, spring, lake or stream. Reference elevation for all observations at the site, e.g. ground elevation, casing elevation. This can differ from the host feature elevation, or be more specific. Type of monitoring site, e.g. well, gauging station, etc. Any natural situation where groundwater flows to the surface of the earth. Name or ID of the spring. Position of the feature. Reference elevation for all observations at the site, e.g. ground elevation, casing elevation. Type of spring e.g. mineral, thermal, saline, etc. The cause of the spring e.g. artesian, geyser, perched, etc. Related geology features, e.g. borehole, unit, etc. The fluid body being depleted by the spring. The hydrogeologic unit(s) hosting the spring. Spring construction details, if any. The periodicity of the spring e.g. ephemeral, perennial, intermittent, seasonal, etc. Any licence relating to the spring. Specialization of the OM_Observation class to allow defining the log start end depth for coverages. For Stratigraphic logs, the observedProperty will be a GeoSciML:GeologicUnit/name. For Lithologic logs, the observedProperty will be a GeoSciML:GeologicUnit/composition/CompositionPart/material. The start of the log measured as a depth from the reference elevation. The end of the log measured as a depth from the reference elevation. Relates a geology log with a particular collection of values (the result) that represent the group of measurements taken in intervals along the length of the log. A shaft or hole sunk, dug or drilled into the Earth to observe, extract or inject water (after IGH1397). The fluid body occupying the well. Constructed depth of the well. Construction details for a well. The area or volume surrounding a pumping well or other discharge site that encompasses all areas and features that supply groundwater to the well or discharge site. Surface location of the well. Purpose of well, e.g. extraction, injection, observation, dewatering, cathodic protection, decontamination, disposal, FlowingShot, Geotechnical, Mineral, MonitoringlevelHead, MonitoringQuality, Oil, OilExploratory, Seismic, WaterExploratory, etc. Reference elevation for all observations at the site, e.g. ground elevation, casing elevation. Depth of the fluid body (e.g. piezometric level). Status of the well, Can be new, unfinished, reconditioned, deepened, not in use, standby, unknown, abandoned dry, abandoned insufficient, abandoned quality. (gwml1) Total length of the well from reference elevation. The aquifers or confining beds intersecting the well. E.g. Agricultural, Domestic, Industrial, Recreation. Estimated or calculated yield from a well. Licence relating to the drilling of the well or to the extraction of groundwater. Relates a GeologyLog with a well. A class to capture the elevation information about a well to enable applications that cannot handle 3D data. Numeric value, coordinate reference system (CRS), and unit of measure (UoM) for the elevation. Description of the accuracy of the elevation measurement. Type of reference elevation, defined as a feature, e.g. Top of Casing, Ground, etc. Method used to measure the elevation, e.g. GPS, Survey, DEM, etc. Licence relating to the drilling of the well or to the extraction of groundwater. Identifier of the licence. Role of the licence. Fluid volume associated with the licence. The period of time for which the licence is valid. The value of the log property at a depth interval along the log. Start depth of the interval along a log. End depth of the interval along a log. Value of the log property.
