Methods and apparatus for distributed temperature sensing (DTS) include marking one or more points at known locations along a waveguide or fiber of a distributed temperature sensing (DTS) system and applying position information from such marked locations to DTS measurements. A Bragg grating in the waveguide or fiber may provide a discrete marker for identification of the position information. Application of the position information from such marked locations to the DTS measurements avoids ambiguous interpretations of other inherent features to assess location and enables data analysis referenced by the known locations to correlate the DTS measurements in space.
