Add skills for Linear Referencing Systems (LRS) as part of Oracle Spatial

Linear referencing associates attributes or events to locations along a linear feature using a single parameter — the measure — instead of two coordinates (longitude/latitude or x/y). It is widely used in transportation (highways, railroads, transit routes) and utilities (gas and oil pipelines) applications.

The advantage of linear referencing is that sections of a linear feature can be referenced and created dynamically by indicating start and end measures along the feature, without explicitly storing their coordinates. This is called dynamic segmentation.

The Oracle Spatial LRS API (the SDO_LRS package) provides server-side linear referencing at the cartographic level. Linear measure information is integrated directly into the SDO_GEOMETRY structure, and the API serves as a foundation for third-party or middle-tier applications implementing virtually any linear referencing method or model in any coordinate system.
