v2.4.0
Reuse spectral curves across areas (Analogy Lab upgrade)
A spectral curve you save in one area can now be used in another. Pull a curve from a pixel, save it to your spectral library, and pick it as the reference in the "Find Similar" tab of any project. So you can take a known signature from one site and go looking for geological analogues somewhere else entirely.
A guided spectral exploration workflow
A new side panel walks you through spectral exploration one step at a time, from setting up your area, through cleaning the signal and loading layers, to validating results in Analogy Lab and defining a final target. Every stage is labelled, so you always know where you are and what comes next.
One "+ ADD" button in the sidebar
The separate buttons for requesting data, uploading files, and creating spectral targets are now a single "+ ADD" button with a dropdown: draw a shape, run AI Spectral Targeting, add preset layers, request more data, or upload your own. Fewer buttons, same options.
Bug fixes
Sublayers now behave predictably the first time you load them onto the map.
Source labels in the spectral targets influence diagram now show correctly.
Map attribution styling now matches the rest of the app.
The glossary page uses the app's own scrollbar instead of the browser default.
