Open In

The Open in … split button (bottom of the General section; also in the historical timeline footer) opens the current viewport in another web viewer, carrying the camera position over so you land on the same spot. Picking a destination from the dropdown opens it immediately and remembers it as the default for the main button.

Destinations

• Iconem River-REM — rem.prod.heritagewatch.ai — river-relative elevation models (REM) for the river in view
• Iconem Search-EO — search-eo-imagery.iconem.com — search commercial/open EO imagery catalogs over the area
• ESRI Wayback Machine — livingatlas.arcgis.com/wayback — opens on the newest Wayback release at this location (the same archive the app's own historical timeline scrubs)
• Google Maps 3D — google.com/maps — Maps' photorealistic 3D globe layer, tilted view
• Google Earth Historical (web) — earth.google.com/web — top-down with the historical-imagery layer enabled
• Google Earth 3D (web) — earth.google.com/web — oblique 3D framing, no historical layer
• BBBike MapCompare — mc.bbbike.org/mc — four basemaps of the same viewport side by side

The zoom-to-camera translation is destination-specific — e.g. the Google Earth/Maps links convert the map zoom into a viewing altitude, and ESRI Wayback gets the latest release id resolved live for the current location.

Custom destinations

Add custom… accepts your own URL template with either placeholder family:

• {lat} / {lng} / {zoom} — e.g. https://example.com/?lat={lat}&lng={lng}&zoom={zoom}
• slippy-tile {z} / {x} / {y} — e.g. https://example.com/#{z}/{x}/{y}

Custom entries appear in the same dropdown and can be removed from it at any time.
