Abstract
Abstract The popularity of geotagged social media has provided many research opportunities for geographers and GIScientists in the digital age. This article reviews innovative approaches to studying spatially linked social media, and applies lessons taken from qualitative GIS and geographic visualization to improve these approaches. I introduce the idea of “code clouds” as a potential technique for the qualitative geovisualization of spatial information. Code clouds can depict and visualize analytic codes, or codes identifying key ideas and themes, that are generated through digital qualitative research. Rather than transforming qualitative forms of data into categories or numbers, code clouds attempt to preserve and represent the context of data as a visualized outcome of qualitative analysis. I use examples from an exploratory case study of geotweets in King County, WA, to demonstrate how code clouds can be applied to the production of meanings through qualitative geovisualization.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
