Linguistic atlas is a science that records linguistic phenomena on geographical maps, in order to know their regional positions and characteristics. In light of this, the present study deals with a new science, which is geographical linguistics, that the ancient Arabs had significant contribution in it, to laying out its origins, by their research in the languages of the tribes and their dialects. As for the modern name and the completion of atlases, it is counted for Westerners. This field is increasing with the emergence of digital atlases, and the provision of a database.
 In this research, we will provide a reading of the German researcher Bergstraße's methodology in making an Arabic atlas, and explain the extent of his contribution to establishing a database that helps researchers to embody their achievements in this field.
 This researcher has studied the following language levels: the phonemic level, such as the form of pronouncing Kaaf, the level of formulas and pronouns, and the level of vocabulary. He used the descriptive approach, which is an approach based on recording linguistic real events.
