A virtual professional community to support effective use of remotely sensed imagery
Bibliographic record
Abstract
This paper introduces an idea of establishing the GeoTruth Virtual Professional Community (VPC) for Image Analysis in Remote Sensing - a collaborative framework for professionals, using ground truth terrestrial photographs for interpretation and analysis of satellite and aerial imagery. The proposed utility-driven community is initially formed by members involved in developing an open-source GeoTruth Engine – a collection of Web-based geo-data media tools, serving as a community-open participatory mechanism for collection, storage, distribution and analysis of geographically referenced landscape photographs and corresponding metadata. The paper investigates conceptual issues of collaborative networks related to establishing and evolving the GeoTruth VPC, describes basic life cycle development and operational principles, outlines possible implementation strategies for the GeoTruth framework, and finally elaborates on corresponding copyright and legal issues.

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.
