Workspace & Sessions

FastGIS saves your work automatically and lets you create named workspaces that survive page refreshes, browser restarts, and device switches.

What is saved

A session captures the full state needed to resume work:

Category	Details
Connection	Base URL, environment (location + mapset)
Camera	CesiumJS camera position, heading, pitch, roll
Layers	All map layers — kind, name, visibility, opacity, order
Profile tool	Raster selection, waypoints, resolution, chart result
Histogram tool	Raster selection, nsteps, null value, bounding box, chart result
Run Module	Last module name and arguments

Autosave

Autosave is automatic and invisible. When you navigate away from the GRASS Runner the current state is written to localStorage. When you return within 24 hours the state is restored silently.

No action is required — autosave is always on.

Named sessions (Workspace panel)

The Workspace section in the left panel lets you save and reload named snapshots.

Saving a session

1. Expand the Workspace section
2. Type a name in the Session name field
3. Click Save — the session is stored server-side under your user account

Loading a session

1. Expand the Workspace section
2. Select a session from the list
3. Click Load — all state is restored in order:
   • Connection and environment first
   • Layers and camera after the viewer is ready
   • Tool panels and charts last

Deleting a session

Select the session and click Delete.

Restore order

If restore partially fails (e.g. a raster no longer exists), the error is logged to the terminal and restoration continues with the remaining state. The app is never left in a broken state by a failed restore.
