Advancing Maritime Security Through Data-Driven Analysis
WHAT’S NEW
Shipped: Prefix-aware STAC typing
Schema-driven typing closes the gap between LinkML definitions and the debrief: keys our writers actually use, so a typo now fails at build time.
Read MoreShipped: Briefing renderer honours Trail display mode
Exported briefings now honour Trail mode — each track grows from its start to the current playback time, mirroring what the author saw in the app.
Read MoreShipped: Overlap warnings for time-range storyboard scenes
A passive, dismissible warning when two time-range Storyboard Scenes accidentally cover the same stretch of time.
Read MoreShipped: Retiring the session sidecar
The sidecar is gone. A plot is now two files, and the whole interactive view rebuilds from features.geojson alone.
Read MoreShipped: All-or-nothing plot saves
A plot save now lands all-or-nothing — after any interruption you reopen the complete new plot or the complete previous one, never a torn half.
Read MoreShipped: Tolerant loading for an orphaned playhead
Plots with an out-of-window saved playhead now open, clamping the playhead to the nearest window edge with a non-blocking notification.
Read MoreShipped: Air-gapped briefing zip renderer
A single zip carries a Storyboard, basemap tiles, thumbnails and SPA — unzip, double-click index.html, watch it play offline.
Read MoreShipped: Air-gapped briefing zip — Storyboard renderer SPA
A Debrief Storyboard now leaves the tool as a single zip. Double-click index.html, the briefing plays — no install, no server, no network.
Read MoreShipped: Schema-rooted STAC envelopes
One LinkML source, generated fan-out — the STAC catalog cluster joins the schema-first regime.
Read MoreShipped: Properties Panel — feature & sub-feature editing
The Properties Panel now edits features, single vertices, and multi-select summaries — with read-only detection and one-click revert.
