Off-Nadir Delta
Google Earth Pro Alternative

A Google Earth Pro Alternative for Dated Satellite Imagery

Google Earth Pro for desktop stops being available for download on June 25, 2027. If what you used it for was seeing how a place looked on a given date, Off-Nadir Delta does that in the browser with open Sentinel imagery — and it is not a copy of Google Earth.

Quick answer — what Off-Nadir Delta is

Google states that as of June 25, 2027, Google Earth Pro for desktop will no longer be available for download; existing installations keep working, and Google points users to Google Earth on the web and mobile. Off-Nadir Delta is a different kind of alternative: a browser map of open Sentinel-2 optical and Sentinel-1 radar scenes by date, with terrain, GeoTIFF/GeoJSON upload, and area monitoring — Sentinel-1 and Sentinel-2 are on the free plan. It has no Google basemap imagery, 3D globe, or KML/KMZ import.

What to use instead of Google Earth Pro

Google Earth on the web

Google’s own recommendation. Google says it has the desktop app’s most popular features and historical imagery, and it publishes a guide for moving KML/KMZ and My Places files over. Start here if you want Google Earth itself.

QGIS or Copernicus Browser

QGIS is free and open-source desktop GIS for Windows, Mac and Linux. Copernicus Browser is the official Sentinel browser; it needs a free account and supports timelapse and download.

Off-Nadir Delta

For dated Sentinel scenes, terrain and your own rasters on one map, and for having an area watched over time rather than re-opened by hand.

Sentinel-2 by Date

10 m optical scenes with True Color, False Color and indices like NDVI. On the free plan.

Sentinel-1 Radar

C-band SAR that images through cloud and at night. On the free plan; NISAR L-band is on paid plans.

Terrain

A Copernicus DEM (GLO-30, 30 m) elevation layer on the map — a 2D layer, not a 3D flythrough.

Your Own Data

Upload GeoTIFF, Cloud Optimized GeoTIFF or GeoJSON and overlay it. KML/KMZ needs converting to GeoJSON first.

Watch an Area

Put an area on the Watchlist and it is re-measured as new passes arrive. One area on the free plan.

Paid Plans

VIIRS nighttime lights, NISAR radar and two-date change detection are on paid plans.

How It Works

1

Create a free account and open the map

Off-Nadir Delta runs in the browser; there is nothing to install. The map needs an account, and a free one is enough to start.

2

Pick a place and a date range

Search Sentinel-2 optical and Sentinel-1 radar scenes over the area and add the dates you want as layers.

3

Compare dates on the map

Toggle between scenes from different dates, switch to False Color or an index like NDVI, and add the Copernicus DEM terrain layer.

4

Leave the area watched

Put the area on the Watchlist and it is measured again as new passes arrive, instead of you reopening the map to check.

Frequently Asked Questions

Is Google Earth Pro being discontinued?▼
Google’s help page states: "As of June 25, 2027, Google Earth Pro for desktop will no longer be available for download." In the linked announcement, the Google Earth team says you can continue using the desktop app, and that if you are an existing user or download it before June 25, 2027, you can keep using it "like you always have even past that date." What ends is new downloads.
What does Google recommend instead?▼
Google Earth on the web and on mobile (Android and iOS). Google says the web version includes the desktop app’s most popular features, that historical imagery is available there, and that it recently added shapefile import, an elevation profile, and a flight simulator. Google also publishes a step-by-step guide for bringing KML/KMZ and My Places files into Google Earth on the web. If you want the Google Earth experience itself, that is the direct path.
Is Off-Nadir Delta a replacement for Google Earth Pro?▼
Not a like-for-like one. Off-Nadir Delta is a 2D web map with an OpenStreetMap basemap: it has no Google basemap imagery, no 3D globe or terrain flythrough, no KML/KMZ import, no Google historical-imagery slider, and no print layouts or movie maker. What it does is different: it shows open Sentinel-2 optical and Sentinel-1 radar scenes by acquisition date, lets you compare those dates, overlays terrain and your own GeoTIFF or GeoJSON, and watches an area over time. If your use of Google Earth Pro was "what did this place look like on a given date, and has it changed", that is the overlap.
How sharp is the imagery compared with Google Earth?▼
Coarser. Sentinel-2’s finest bands are 10 m, and the terrain layer is the 30 m Copernicus DEM (GLO-30). You will see fields, burn scars, flooding, construction sites and coastline change, not individual cars or rooftops. The trade-off is that each scene is a dated acquisition you can put next to another date, and Sentinel-1 radar sees through cloud and at night.
Can I open my KML or KMZ files?▼
No. The map accepts GeoTIFF (including Cloud Optimized GeoTIFF) and GeoJSON; KML, KMZ and shapefiles are not accepted, so convert them to GeoJSON first (QGIS can do this). Google Earth on the web is the place that imports KML/KMZ directly.
Is it free, and do I need an account?▼
There is a free plan. It includes Sentinel-2 and Sentinel-1 on the map, the terrain layer, GeoTIFF/GeoJSON upload, and one monitored area on the Watchlist; imagery rendering and processing are metered in tokens. VIIRS nighttime lights, NISAR radar and change detection are on paid plans. The map needs an account (a free one is enough); the in-browser GeoTIFF viewer on the GeoTIFF Upload page works without one. The pricing page has the current split.
