| Check | What it checks | Measured | Expected | Cannot catch | ||
|---|---|---|---|---|---|---|
| not run | PACK-004 non-blocking | Upstream sources are recorded | — | at least one source, each with a non-empty edition and a 64-hex sha256 | A recorded source that is not the one the build actually used, and an edition or sha256 that is well formed but wrong. | Note: No upstream sources were supplied to the report (--sources). |
| not run | TER-005 non-blocking | Spot heights against published airport field elevations | — | Provisional threshold: median |difference| at most 50 ft, and no airport beyond 500 ft that was not beyond it in the previous edition. Needs an airports pack (--airports) | Errors away from airports, and errors smaller than the outlier bound. Copernicus is a surface model (trees, buildings, rooftop helipads), and a bad FAA elevation looks the same as a bad tile: the check says where they disagree, not which one is wrong. Against a previous record without TER-005 metrics it judges the median only; only the worst 200 outliers are carried. | Note: No airports pack was given (--airports) to take field elevations from. since TV7 |
| pass | PACK-001 | pack_meta is readable and names a known kind | id=terrain-us-central kind=terrain cycle=2024edr2 schema_version=1 | pack_meta present; kind is one the device knows | A pack_meta that is well formed but names the wrong id or cycle for the bytes inside. | |
| pass | PACK-002 | Attribution and license are recorded in pack_meta | attribution and license present | both non-empty | A license tag or attribution that is present but wrong for the data. | |
| pass | PACK-003 | Origin label is federal, community or user-supplied | federal (passed with --origin) | one of federal / community / user-supplied | Whether the label matches where the data really came from. For a kind with a default label (ORIGIN_BY_KIND in packtools/report.py) the label comes from that table, not from the builder or the pack, so the check is tautological and always passes; measured says which. With --origin it shows only that the label given is one of the three. | since AER-699 |
| pass | ACC-001 | Device acceptance: pyEfis's own reader opens the pack and answers a fixed query set | opened; 1/1 queries returned data | the reader opens the pack and every query returns data | Wrong values the reader accepts. It shows the device can open and query these bytes, not that what it returns is right. The queries cover fixed points only: US kinds, 5 CONUS metros (Denver, Seattle, Atlanta, Los Angeles and Chicago); airports (Canada), Toronto and Vancouver; water, Puget Sound, Lake Michigan and Lake Ontario; navaids, idents DEN, SEA, LAX; procedures, airways V23, J80, V1; terrain, one native tile or the coarsest mosaic level. So it cannot catch a missing Alaska, Hawaii or Puerto Rico, or any state or province that holds none of those points. | |
| pass | TER-001 | Every member is a known terrain file of a valid size | 4,044 members, 0 malformed | 0 malformed members | A tile of the right size holding wrong elevations. | |
| pass | TER-002 | Native tiles fall inside the pack's region | 311 native tiles (previous 311), 0 outside us-central | 0 tiles outside the region bbox; a regional pack with no native tiles fails (only the terrain-mosaic pack, by id, carries none) | A tile missing from inside the region (ocean tiles are absent by design, so the check cannot tell a gap from sea). | |
| pass | TER-006 | No native tile of the previous edition is missing | 311 native tiles (previous edition 2024edr1: 311); lost 0; gained 0 | every native tile in the previous edition is still present. Applies across Copernicus editions too: a new edition that drops a tile fails | A tile that is present but holds wrong or older elevations, and a tile that was already missing from the previous edition. | since AER-4102 |
| pass | TER-003 | Every masked .hgt carries its .wmask water mask | 0 | 0 missing masks | A mask that is present but wrong. | since AER-2287 |
| pass | TER-004 non-blocking | Elevation range and void fraction on a sample of tiles | 16 of 311 native tiles: min -8 m, max 2,198 m, void 0.0% | -500 m to 9,000 m, void at most 50% | Anything in a tile that was not sampled, and wrong elevations that stay inside the plausible range. | |
| pass | TER-007 non-blocking | Every Copernicus tile inside the region is present | 311 of the 311 Copernicus tiles inside us-central present; 0 missing | every GLO-30 tile that exists inside the region (packtools/data/glo30_tiles.txt, from the Copernicus tile list) is a native tile of the pack | A tile that is present but holds wrong or older elevations, and a tile Copernicus itself does not publish. | since TV7 |
| pass | TER-008 non-blocking | Void share of every native tile | 311 native tiles read; 0 with more than 1% void; worst N48W104 0.00% | no native tile more than 1% void (GLO-30 has no voids; ocean is 0 m) | Voids at or under 1% of a tile (up to about 130,000 posts of a 3601 x 3601 tile), wrong elevations that are not void markers, and voids in the mip levels and mosaic (only native tiles are read). | since TV7 |

What this report is and is not
These are the checks we ran on this pack, what each one measured, and what each one cannot catch. It is evidence, not a warranty and not a certification. No authority has reviewed or approved this data or these checks. Passing them does not mean the data is correct, complete or current. Results marked as coming from Auspex come from a proprietary AI test engine whose method is not published; each of its findings is stated so you can check it yourself. This data is for Experimental / Amateur-Built use. This data is provided as-is with no warranty and any use of the data is at your own risk. Verify against official publications.
