概要	Grounded visualization is a mixed-methods analytic approach that weaves grounded-theory qualitative analysis together with GIS-based spatial visualization, so that emerging codes and maps inform one another iteratively rather than sequentially. Instead of mapping results after the qualitative analysis is finished, the analyst moves back and forth: a pattern noticed while coding interviews prompts a map, the map raises a spatial question that sends the analyst back to the text, and so on. The aim is an interpretation that is simultaneously grounded in participants' accounts and attentive to the geography in which those accounts are situated.	The ethnographic interview, formalized by James Spradley, is a deliberately staged conversation whose goal is to discover how an insider categorizes and talks about their own cultural world rather than to test the researcher's categories. It proceeds through a developmental research sequence of question types — broad grand-tour questions, fine-grained descriptive questions, structural questions that probe how knowledge is organized, and contrast questions that surface the distinctions informants draw between terms. The point is not a list of facts but a reconstructed map of meanings expressed in the informant's own native terms.	Grounded Theory (GT) is a systematic qualitative research methodology in which theory emerges directly from data through iterative analysis, rather than being imposed before data collection. Developed by Barney Glaser and Anselm Strauss in 1967, GT prioritizes generating explanatory frameworks grounded in evidence.
