How to use
Click any reef, island, rock, bank, cay or similar feature to see its attributes and export options in the side panel.
Shift-click features to build a multi-feature selection — each feature is added to the list in the side panel. Shift-click again to remove it. Click the × next to any row to remove that item. A regular click clears the multi-selection and returns to single-feature mode.
Hover over a feature to see its local name and reef ID in a tooltip.
Search by typing a name in the box at the top of the side panel — suggestions appear as you type; use ↑↓ Enter to navigate, Esc to dismiss.
Draw › Polygon or BBox to select and export multiple features by area. After drawing, a panel in the lower-left shows the WKT and bounding box coordinates with Copy WKT and Copy BBox buttons.
Clear resets the drawing, the selection, and the search box.
Labels toggle shows feature names at zoom ≥ 9.
Colour switches between feature-type colours and a single neutral colour; the legend is shown or hidden automatically.
The sun / moon button in the header toggles between dark and light themes; your preference is remembered across sessions.
Polygon geometry loads in the background after the initial centroid view — export buttons that require full geometry are enabled automatically once it is ready.
Export
The export panel always includes Name, Type, UNIQUE_ID and Centroid (lon/lat in WGS84).
Toggle any combination of optional fields before exporting:
WKT — full polygon geometry as Well-Known Text.
BBox — bounding box (minX, minY, maxX, maxY) plus a WKT representation.
Buffer — applies a buffer (0–100 km, set with the slider) to the polygon before computing WKT and/or BBox; adds a buffer_km column.
WKT, BBox and Buffer are enabled automatically once full polygon geometry has loaded in the background.
Choose CSV or JSON format, then use Copy to send the data to the clipboard
or Download to save it as a file.
All coordinates are in WGS84 (EPSG:4326).
