+# Imaging sensor pack
+
+Swath widths and ground resolutions for 46 Earth-observation platforms and
+constellations, matched to satellites by NORAD catalog number or by their
+CelesTrak name. The orbital view draws a satellite's sensor swath to scale and
+lets it zoom past 8x only as far as that swath (`src/layers/satellites/sensors.js`,
+`src/data/imagingSensors.js`, `orbitalMaxZoom` in `src/cockpitOrbital.js`).
+
+| File | Content | Entries |
+|------|---------|---------|
+| `imaging_sensors.json` | Platform, match rule, operator, instruments, altitude, imaging modes (swath km, best ground resolution m), narrowest standard swath, sources, unverified fields | 46 |
+
+**Compiled:** 2026-11-04, by hand from the pages cited per entry (`sources`).
+Each match pattern was checked against CelesTrak's active list that day.
+Altitude is the nominal value from a cited source; where none was found it is
+the median altitude of the matching satellites from CelesTrak GP data, noted in
+`unverified`. The app zooms on the live altitude, not this one.
+
+**Narrowest standard swath** is the narrowest continuous standard imaging swath
+or scene width (cross-track); for a geostationary imager, the narrower side of
+its smallest standard scan area. Some listed modes are left out of it:
+
+- Sampling modes: SAR wave vignettes, and Himawari's Landmark Area scans
+  (1000 × 500 km), so Himawari's narrowest is the 1000 km Target Area.
+- Generations the operator has retired: PlanetScope's Dove Classic and Dove-R
+  (about 25 km scenes, imagery until April 2022 per Planet) stay in `modes`,
+  while its narrowest is the SuperDove's 32.5 km. The `^FLOCK ` name rule
+  would also match those older Doves.
+
+**Unverified values.** A value not confirmed on an opened page is named in the
+entry's `unverified` list. `swathConfirmed` is false when the narrowest swath is
+missing or unverified; such a platform keeps the base 1–8x zoom steps:
+
+- Landsat 9 (swath inferred from Landsat 8), ResourceSat-2 (LISS-3 swath),
+  SuperView Neo-1 (12 km from search snippets only), BlackSky and Meteosat
+  MTG FCI (no swath found).
+
+## Sources and licences
+
+The values are individual specification facts, each cited from the
+operator's or agency's official pages listed per entry in `sources`. No text or
+images are copied. The main sources:
+
+- **Operator and agency pages and spec sheets** (NASA, USGS, NOAA/NESDIS,
+  ESA SentiWiki and Earth Online, EUMETSAT, JAXA, ISRO/NRSC, INPE, CSA, DLR,
+  JMA, ASI, KARI, China's Ministry of Natural Resources (LASAC), Planet,
+  Vantor (formerly Maxar) datasheet pages, L3Harris, China Siwei, BlackSky,
+  Airbus and KOMPSAT-5 via the Disasters Charter, ICEYE, Capella, Umbra,
+  Satellogic, Chang Guang).
+- **Academic papers and proceedings** (Sensors papers on Gaofen-3, KARI's
+  ACRS 2012 paper on KOMPSAT-3, CAST's IAC-16 abstract on Gaofen-2).
+- **eoPortal** (ESA's mission directory, an institutional source): a swath
+  read there counts as confirmed. It is cited beside the operator's and
+  agency's pages, and alone for values they do not give (the wider modes of
+  Gaofen-3 and COSMO-SkyMed Second Generation, and a few other entries).
+  Gaofen-1 takes eoPortal's 69 km PMS and 830 km WFV swaths by maintainer
+  choice; a 2019 Chinese lecture and a Sensors paper give 60 and 800 km.
+- **CEOS MIM Database** (https://database.eohandbook.com): CC BY 4.0 since
+  7 September 2026, with the credit "CEOS MIM Database,
+  https://database.eohandbook.com". No entry relies on it yet; credit it if
+  values are taken from it later.

+The same release is mirrored on Hugging Face as

+patterns instead.

+(openpyxl). The file's `meta` header records the curation.
+
+**Curation:**
+
+- Kept columns: Operator/Owner, Country of Operator/Owner and Purpose, the
+  ones the layer reads. Everything else (detailed purpose, users, orbits,
+  masses, contractors, launch data, sources) is left out.
+- Repeated text is stored once in `strings`; each record is
+  `[noradId, operator, operatorCountry, purpose]` with string-table indexes,
+  `0` meaning empty.
+- The 3,996 Starlink rows are dropped: every Starlink object is classed and
+  credited to SpaceX by name, so they would only add size.
+- Rows without a readable, positive NORAD number are dropped and counted apart
+  from duplicate NORAD numbers (the first row of a duplicate is kept); both
+  counts are 0 in this release.
+- Owner countries stay as UCS writes them ("USA", "USA/Japan", "ESA",
+  "Multinational"); `src/layers/satellites/classes.js` normalises them, together with
+  CelesTrak SATCAT owner codes, in one table.
