This article presents a methodology for data collection and documentation of microtoponyms in the Upper Carniola/Gorenjsko dialect of Slovenian based on visual and audio recordings. Special attention is placed on transcription (phonetic or simplified phonological transcription and standardization), which should be based on a morphological analysis of the toponyms examined. Linguistic analysis and its consideration of the dialect characteristics of toponyms can help reconstruct their naming motivation and origin. The article presents selected toponyms lexicographically and cartographically.
