Bookmarks

Saving and organizing views

A bookmark is a name, a thumbnail, and the full URL query string at the moment it was saved — since nearly all app state already lives in the URL (see Setup), restoring a bookmark is just re-applying that saved query string.

The Bookmarks section: Save View, Gallery, and three saved projects (Grand Canyon, Patagonia, Matterhorn) each with multiple visualization-mode views

Bookmarks panel — three projects (Grand Canyon, Torres del Paine/Patagonia, Matterhorn), each with multiple saved viz-mode views

Projects and views

  • Save View creates a project (the viewport + a first child capturing the current visualization settings).
  • Each project can have multiple children — same viewport, different visualization-mode combinations — added via the + button on a project row.
  • Restoring a child while its parent project is already active leaves the camera alone (only the visualization settings change); restoring a bookmark from a different project eases the camera to its saved viewport.

Organizing

  • Drag to reorder projects, or reorder/reparent children within their own project.
  • Fold/expand individual projects, or all of them at once.
  • An Edit toggle exposes rename/delete on every row (kept out of the way during normal day-to-day use).
  • The Gallery view shows every bookmark as a sortable, flattenable grid — useful once the list gets long.

The Gallery view — Featured strip plus every saved bookmark as thumbnail cards

Bookmarks Gallery — built-in Featured strip (Matterhorn, Grand Canyon, Paris historical, Iceland overlay) plus this session's own saved views below

Import / Export

Export the full bookmark list as JSON, or import one — importing merges by id, so re-importing a previously exported file updates existing entries in place rather than duplicating them.

A small set of curated example viewpoints — different terrain shapes (mountains, canyon), different visualization combinations (hillshade, hypsometric tint, sky-view factor), and a historical-imagery example — ships with the app under a Featured strip above your own bookmark list. These are read-only and separate from your personal list: restoring one never edits or removes it, and your own saved bookmarks are never affected by an app update to this set.
