GB/T 30170.2-2016 Geographic information—Spatial referencing by coordinates—Part 2:Extension for parametric values
Abstract
This part, as an extension of GB/T 30170-2013, specifies the conceptual model for describing spatial references using parameter values or functions. It adopts the model of GB/T 30170-2013, combining a location expressed in coordinates with a parameter value to form a spatial parameter coordinate reference system (CRS). This spatial parameter coordinate reference system can be extended to include time. This part is applicable to producers and users in the field of environmental information. Those parameters that are attributes of spatial locations or elements but are not related to spatial references are not included in this part.
