The rationale to create a special profile is to inform the data consumer that calculation of relative position into absolute position can be greatly simplified. Vertical wells are very common and several groundwater applications expect them to be vertical.

Each Log Value is composed of a pair of properties to locate the element along the Well path fromDepth and toDepth and a SWE DataRecord that contains an arbitrary set of fields to report properties of interest along the path see Figure 20. Figure 20 : SWE Data Record. SWE Clause 7.3 of OGC 08-094r1 describes the requirements to encode a DataRecord. A community that defined a common Geologic Log encoding should agree on a definition and scoped name for the DataRecord, and definitions of the individual fields composing the record. 100 Copyright © 2016 Open Geospatial Consortium For example, a community that wants to use GeoSciML vocabulary to encode a geology log can agree on a field type eg: SWE Category and a definition a URI to flag that field in the DataRecord as having controlled content. Another community might chose to constrain the complete DataRecord by agreeing on the scoped name of the DataRecord itself. × Ø eq × Ù wml2 Ú well Ú geologi Û Ü Ý Ù× log Ú definition Þ ß à á â ã ä alue of a Geologic á âã å æ OU á ç use a community controlled definition for the DataRecord and è or the fields that compose it.
