Iran Linguistic Atlas (ILA), funded by the Research Institute for Cultural Heritage and Tourism (RICHT), is a research project for mapping the linguistic diversity of Iran. The project is aimed at recording unified and comparable data from every spoken dialect of Iran’s rural areas and producing self-organized colored maps of this diversity using a specialized software program. Its initial phase began around the mid-1970s in the form of a joint project by the then Iranian Academy of Language and the National Geography Organization. In 2001, the documented data was handed over to the Cultural Heritage Organization, to be saved and expanded. The Iran Linguistic Atlas has now been redefined as an automatic linguistic atlas with the capability of producing self-organizing colored maps according to the operator’s choices. In this article, the ILA, its background and the state of its current phase is introduced. The nature of its data, its earlier and recent field methods, its audiotapes, digital databases and computer databases of phonetic transcriptions are described. In addition, ILA software program is presented and its capability for creating automatic colored maps is discussed thoroughly.
