Importance of the MAND

The MAND is unique in its kind. Language atlasses which illustrate morphological phenomena are available, but are quite unlike the MAND in their limited scope and depth. In those atlasses a morphological process will be illustrated by a single word. The MAND illustrates such a process by a large number of words. The first volume, for example, contains 40 main maps on pluralization.
Many maps on subsidiary problems and tonal issues accompany the main maps.

The Goeman-Taeldeman material allows also for generalizations: the example, vowel length in the plural of the type 'dag-daagen', provides an interpolation of a synthesis of the data of seven words. The effect is a better visualisation of differences.
Mapping techniques as these allow for the prediction of the situation for localities for which there are no data available.

This technique is called universal Kriging:
