ABSTRACT
The concepts of orientation microscopy and orientation mapping were introduced in Section 1.2.3. Orientation microscopv refers to the (usually) automated measurement and storage of orientations according to a pre-defined pattern of coordinates on the sampling plane of the specimen. The pictorial output of these orientations with reference to the sampling coordinates provides a map of the spatial orientation distribution, i.e. derives the 'orientation topography'. Once this basic information, i.e. orientation plus position, is stored it can be processed according to
e The orientations themselves
e Pattern quality
In the final output various methods of colouring, symbols or shading can be used to convey and depict aspects of the orientation topography. These outputs are known collectively as orientation nzaps.
