- Imported metadata stays inert: descriptions, native labels, properties and
KML extended data are dropped from every entity; names are kept as short
plain text. GeoJSON loads with a describe that builds no HTML, and
simplestyle (including marker-symbol) is dropped, so no icon asset is
fetched for a file and GeoJSON draws in its row's color.
- Bound geometry before loading: features and vertices are counted in the
parsed GeoJSON, the KML document and while reading GPX, and a file over
20,000 features or 250,000 vertices is refused before Cesium builds it.
- Imports run one batch at a time, so concurrent picks or drops cannot pass
the 12-file cap.
- Fly-to framing walks long tracks by index instead of spreading them into a
call.
- Fly-to is an immediate navigation through the application shell; the fly
after an import is a deferred navigation stamped when the batch starts and
re-asserted just before flying.
- Dated imports never change the shared clock: imported sources expose no
clock, entities are available for all time, and a KML gx:Track is drawn as
its line.
- GPX is read into GeoJSON with one line per track segment, without times.
- KML/KMZ rows show a hatched swatch (they keep their own styles); keyboard
focus is kept on the same control after hide/show and moves to the next
row after remove.
- Unit regressions for each, and the rendered QA now imports hostile
metadata, dated KML/GPX and a two-segment track, and fails on any request
for a file's contents or icon assets, a clock change, or surviving
metadata.
