Description:These template materials include an excel workbook and a geodatabase containing empty feature classes for populating geologic data in GeoSciML-portrayal. The Excel workbook provides spreadsheets with the content models for the description properties associated with geologic contacts, faults or shear zones, and geologic units in the GeoSciML Portrayal view schema. The model is based on the IUGS CGI interoperability working group GeoSciML Portrayal view scheme. See https://www.seegrid.csiro.au/wiki/bin/view/CGIModel/GeoSciMLPortrayalViewModel. This schema is a view of GeoSciML data that denormalizes the data and concatenates complex property values into single, human-readable, labels and returns single, representative, values from controlled vocabularies for properties multi-valued properties that can be used when generating thematic maps, or portrayals, of the data. Labels, will be'free-text'fields that will be, in robust services, well-structured summaries of complex GeoSciML data, while the representative thematic properties will be URIs of concepts in a controlled vocabulary. There may also be links, via identifier URIs, to full GeoSciML representations of the geologic features. The geologic unit feature content also conforms closely to the content in the USGS-AASG NCGMP09 database design for a description of map units. These features are essentially geographically located descriptions of outcrop to map scale units of rock--including lithologic composition, age, internal structure (bedding, foliation etc.) and genesis. The content model might be associated with map units on a geologic map, individiual polygons (on a map) or borehole intervals (in a stratigraphic log), or with point locations to describe outcrops in field data. For descriptions assciated with maps or polygons (outcrop areas), location uncertainty properties are not included. Note that since the geometry for geologic unit outcrops is generally a polygon, the full mapped feature cannot be compiled in this spreadsheet, but would have to be assembled in a GIS feature class that has a geometry field. This could be implemented by building the geolgoic unit descriptions in the template here and then mapping the descriptions to individual mapped feature polygons that only have the Label or SpecificationURI populated as a mechanism to join with the geologic unit description table here.
