Photogrammetry software (Agisoft Metashape, Pix4D) could not read the
camera orientation, and the pitch convention was wrong.
- Emit attitude as XMP-Camera:Yaw/Pitch/Roll (Pix4D namespace Metashape
reads) instead of the ignored XMP-GPano:Pose* tags, via a bundled
firemapper.ExifTool_config (stock exiftool can't write that namespace).
- Add session_map.metashape_ypr(): pitch 0 = nadir, +90 = forward, so
thermal -> 0, cam25 -> ~25, cam45 -> ~45, with aircraft attitude and the
platform sweep folded in (decomposed from the shared camera geometry).
- Write a Metashape/Pix4D reference CSV (GPS + YPR per frame) on every
Embed run, as a robust alternative to the embedded tags.
- Fix camera detection to key off each image's immediate parent dir, so
embedding a parent folder that groups several sessions no longer mis-tags
every RGB frame as nadir (dropping the off-nadir mounting angle).

Revised the GUI explanations, on-screen labels and dialogs, the HTML user
manual, and CLAUDE.md to a formal, consistent tone: removed casual phrasing
and contractions, standardised terminology, and documented the new parallel
"--workers" option (CLI) and "Parallel workers" control (GUI). Also added a
manual troubleshooting entry for full-disk GPS loss and a parallelism note to
CLAUDE.md. No functional changes.

Both conversion steps ran their hot loops serially. Now they fan out across a
configurable worker pool (default min(cpu, 16); the rig has 20 cores + NVMe):
- embed_metadata: parallel image copy (thread pool) + tagging split across
several concurrent exiftool processes via new run_exiftool_parallel().
- stretch_thermal: parallel session histogram, parallel render/save, and
parallel exiftool embedding (reuses run_exiftool_parallel); GPS verify +
retry preserved.
- CLI: --workers N on both tools. GUI: shared "Parallel workers" spinbox.
Measured on a 135-frame session (270 embed pairs), workers 1 -> 16:
render+embed 38.9s -> 6.0s (6.5x), embed copy+tag 73.5s -> 13.0s (5.7x),
histogram 1.7s -> 0.7s. 0 frames missing GPS in every run.

EXIF/GPS embedding, session-wide thermal stretch, and an OpenStreetMap
view of trigger points and image footprints, wrapped in a Tkinter GUI.
- embed_metadata.py: write JSON sidecars into image EXIF/XMP, with true
camera orientation (aircraft attitude + platform roll + mounting offset)
- stretch_thermal.py: rescale 16-bit thermal frames to a session-wide
window (8-bit palettes), embedding GPS/orientation EXIF in the output
- session_map.py: shared camera geometry (orientation + oblique footprints)
- firemapper_gui.py: GUI with Embed / Thermal Stretch / Map tabs
Includes CLAUDE.md and an end-user manual (manual.html). Capture data and
derived outputs (tens of GB) are git-ignored.
