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.
Google Earth Pro vs Google Earth on the web vs Off-Nadir Delta
Facts last reviewed 2026-09-29.
| Capability | Google Earth Pro (desktop) | Google Earth on the web | Off-Nadir Delta |
|---|---|---|---|
| Status | No new downloads from 25 Jun 2027; existing installs keep working | Available; Google’s recommended path | Available |
| Runs in the browser | No | Yes | Yes |
| Imagery | Google Earth imagery, incl. historical imagery | Google Earth imagery, incl. historical imagery and 3D | Open Sentinel-2 optical (10 m) and Sentinel-1 radar scenes by acquisition date |
| KML / KMZ files | Yes | yes (Google publishes a migration guide) | no — convert to GeoJSON |
| 3D globe | Yes | Yes | no (2D map) |
| An area re-measured automatically as new passes arrive | Not described by Google | Not described by Google | yes (1 area free) |
| Best for | Keeping an existing desktop workflow | The Google Earth experience, KML projects, 3D | Dated open imagery, change over time, watching an area |
Google facts are from Google’s Update Google Earth Pro help page and the Google Earth team’s announcement and follow-up in the Google Earth Community. Off-Nadir Delta is an independent project and is not affiliated with Google.
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
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.
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.
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.
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.
