Feature Inspector¶
Click anywhere on the map canvas (outside of any active drawing tool) to open the Feature Inspector. The inspector shows what is at that exact point across all visible layers and provides one-click actions to start an agent workflow.
What the Inspector Shows¶
| Section | Contents |
|---|---|
| Coordinates | WGS84 decimal lat/lon of the click point; click to cycle to DMS or UTM format |
| Vector features | Properties of every visible vector feature at that point — layer name, feature ID, all attribute key/value pairs |
| Raster value | Pixel value from the topmost visible analysis-ready raster at that point, with the layer name and units |
| All raster values | Expand to see readings from every visible raster that has pixel data at the clicked location |
Raster readings require a local GeoTIFF with raw pixel values loaded. Python-pushed preview PNGs and GEE tiles do not return per-pixel values. If the raster section is empty, open the Layers panel → click the raster's 🎨 icon → Load raster values.
Actions¶
| Button | What it does |
|---|---|
| Quick Delineate | Runs delineatePoint(lon, lat) immediately in the background — the watershed boundary and outlet appear on the map within seconds without opening the chat |
| Delineate (agent) | Opens the chat panel with a pre-filled prompt describing the clicked location and requesting a full watershed delineation |
| Ask AI | Opens the chat with a context-rich prompt that describes the click point, all visible layers, and any vector features found there — ready for any ad-hoc question |
Cursor Value Probe (Hover Mode)¶
While the Feature Inspector is not blocking, moving the cursor over the map shows a live cursor value in the Map Status Bar for the topmost visible analysis-ready raster — no click needed. This is useful for quickly scanning a raster for value ranges without recording a reading.
Tips¶
- Quick Delineate is the fastest way to delineate a watershed — one click on the outlet, one button press, result in ~5 seconds
- Click a vector feature (watershed polygon, gauge point, MERIT river reach) to see all its properties before asking the agent about it — knowing the HUC8 code or gauge ID lets you write a more specific prompt
- If multiple vector layers overlap at a point, the inspector lists features from all of them — useful for checking whether a point falls inside a flood zone, a specific soil type, and a particular HUC simultaneously
- The Copy coordinates button in the inspector copies the lat/lon to the clipboard in the currently displayed format (decimal, DMS, or UTM)
