Abstract

fetched live from OpenAlex

Spatio-triangulation process, based on a multi-sensor block adjustment, is applied to 40 different VIR and SAR images: Landsat-7 ETM+, panchromatic SPOT-4 HRV, multi-band ASTER, RADARSAT (fine, standard, wide modes) and ERS-1. The images were acquired over Rocky Mountains, Canada from different view/look angles (nadir, across- and in-track) creating various intersection geometries in the overlap areas. Only 1:50,000 paper maps were available for this area. A physical multi-sensor geometric correction model and algorithms developed at the Canada Centre for Remote Sensing were used for the processing. Preliminary results of block formed with all images gave positional errors of around 20-26 m. These errors result from medium-resolution sensors (ERS-1, RADARSAT standard/wide modes, Landsat-7 ETM+), from weak intersection geometry between some images, but these errors also include the 1:50,000 map errors (25-30 m).

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
