Zoom Earth Alternative

A Zoom Earth Alternative for Analysis & Monitoring

Zoom Earth is great for live weather. When you need to analyze high-resolution imagery, monitor areas over time, and connect world events to what satellites see, Off-Nadir Delta picks up where a live map stops.

Quick Answer: Zoom Earth specializes in near-real-time weather and hazard imagery from geostationary satellites. Off-Nadir Delta is an alternative for analysis and monitoring: high-resolution Sentinel-1 SAR and Sentinel-2 optical imagery, area monitoring over time with anomaly detection, NASA FIRMS active fires, and an event-intelligence layer that fuses world events with satellite imagery — all free to start in the browser.

Which one do you need?

Choose Zoom Earth for…

Live weather, storm and hurricane tracking, and watching current conditions with near-real-time geostationary imagery.

Choose Off-Nadir Delta for…

Analyzing high-resolution imagery, monitoring areas over time with anomaly detection, and connecting geolocated world events to satellite imagery.

Event Intelligence

The Watchfloor maps geolocated world events and ranks them by severity — a situational picture, not just weather.

High-Res Analysis Imagery

Sentinel-2 optical (10m) and Sentinel-1 SAR (all-weather) for real analysis, not only geostationary frames.

Monitor Over Time

Track any area as a time series with automatic ±2σ anomaly detection.

Active Fires

NASA FIRMS hotspots overlaid on imagery — then monitor burn extent and recovery over time.

Events × Imagery

Move from a reported event to imagery of the affected area in one tip-and-cue workflow.

Free & Browser-Based

No install, free to start, and the Watchfloor is public to browse.

How It Works

1

Start with the global picture

Open the Watchfloor to see geolocated world events and active fires worldwide — a situational picture, not just a weather layer.

2

Pick an area to analyze

Draw any polygon and pull Sentinel-1 SAR and Sentinel-2 optical imagery — high-resolution analysis data, not only geostationary weather frames.

3

Track it over time

Build a time series of vegetation, water, surface change, or nighttime lights, with automatic anomaly detection when readings deviate from the baseline.

4

Connect events to imagery

When something happens, move from the reported event to satellite imagery of the affected area in the same workflow.

Frequently Asked Questions

What is Zoom Earth best for?
Zoom Earth is excellent for near-real-time weather and hazard awareness: tracking hurricanes and storms, watching wildfires and smoke, and viewing live imagery from geostationary satellites (NOAA GOES, EUMETSAT Meteosat, JMA Himawari) plus twice-daily HD images from NASA Aqua/Terra. It is a fast, free way to see current conditions.
How is Off-Nadir Delta different?
Off-Nadir Delta is built for analysis, monitoring, and intelligence rather than live weather. It provides high-resolution Sentinel-1 SAR and Sentinel-2 optical imagery you can analyze with indices, lets you monitor any area as a time series with anomaly detection, and fuses geolocated world events with imagery on the Watchfloor. Think "understand and track what is changing," not just "see the current weather."
Can I still track wildfires?
Yes. Off-Nadir Delta overlays NASA FIRMS active fire hotspots (VIIRS 375m, updated daily) on satellite imagery, and you can monitor a fire-affected area over time to assess burn extent and recovery — going beyond a live hotspot view.
Is it free and browser-based?
Yes. It runs entirely in the browser with no install, and offers a free tier. The Watchfloor is publicly browsable without an account; token-based pricing covers imagery rendering and deeper processing. See the pricing page for current details.
Does it show high-resolution imagery?
Yes — Sentinel-2 optical at 10m and Sentinel-1 SAR (all-weather, day or night), which are higher resolution and more analysis-ready than the geostationary weather imagery Zoom Earth specializes in. You can also upload your own GeoTIFF or COG files.
