Abstract

fetched live from OpenAlex

The Ontario Geological Survey and the Canada Centre for Remote Sensing are currently preparing a series of satellite based terrain maps for a 250 000 square kilometer area of the boreal forest region in Northwest Ontario. The purpose of this provincial and federal mapping program is to produce a series of 1:100 000 standardized, satellite based engineering-terrain maps that will be published as a provincial map series. The terrain maps are being used to plan forestry roads and other civil engineering works in support of forest harvesting programs in the region. They are also used to verify forest productivity models in the boreal forest. This paper presents the interpretation methodologies and examples of the satellite based standardized terrain maps. Our results show that image maps produced from a combination of DEM and TM can provide a base on which to interpret and overlay engineering terrain units at a scale of 1:100 000 for large areas of the boreal forest regions in northern Canada. This method will result in considerable savings in time and cost when compared to traditional air photo methods.

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.
