For OSINT & investigations

Satellite Intelligence for OSINT

Discover world events, ask an AI intelligence analyst what they mean, and confirm them from space — one browser-based platform, on open data you can legally publish. Built for journalists, researchers, and open-source analysts.

Quick Answer: Geospatial OSINT answers “what is happening, where” using only public sources — open event data plus open satellite imagery. Off-Nadir Delta runs the whole loop in the browser: the Watchfloorsurfaces geolocated events (signal), Delta Agent recommends which sensor and area to image next (collect), and the Map confirms it with Sentinel-1 SAR and Sentinel-2 optical (interpret) — all on openly licensed data you can publish with attribution.

The OSINT workflow: from signal to satellite

A plain imagery viewer assumes you already know where and when to look. Off-Nadir Delta closes the loop — the event surfaces the area, the AI analyst plans the collection, and the map confirms it.

1. Signal · Watchfloor

The Watchfloor surfaces geolocated geopolitical and security events worldwide (Delta Signals, distilled from global news media), ranked by severity. The event tells you where and when to look — you do not have to guess coordinates.

2. Collect · Delta Agent

Ask Delta Agent in plain language. It reasons over the live signals with real GEOINT/OSINT tradecraft and returns a sourced, geolocated brief — recommending which sensor (SAR or optical) and which area to image next.

3. Interpret · Map

Open the finding on the Map to confirm it: stack Sentinel-1 SAR (all-weather, day or night) and Sentinel-2 optical, compare dates, run change detection, and detect vessels — then export on openly licensed data.

Who it is for

Journalists & newsrooms

Corroborate breaking events with satellite imagery, document change over time, and publish on openly licensed data you can legally reuse.

OSINT researchers & analysts

Move from a geolocated signal to the right imagery fast — with an AI analyst that reasons in real tradecraft and shows its sources.

NGOs, humanitarian & policy teams

Watch the places that matter, detect what changed, and brief stakeholders — without GIS software, code, or per-image contracts.

Open data, situational awareness — by design

Off-Nadir Delta uses only public, open sources and cites them. It is built for situational awareness — understanding events and places — not for tracking or targeting individuals. It runs on open Sentinel-class data (~10 m), so it is not a sub-meter provider; pair it with a high-resolution source when you need to identify individual objects.

Frequently Asked Questions

What is geospatial OSINT?
Geospatial OSINT (open-source intelligence) is the practice of answering "what is happening, where" using only publicly available sources — news and event data, plus open satellite imagery — rather than classified collection. A typical workflow localizes an event in space and time from open event data, then confirms and measures it with satellite imagery. Off-Nadir Delta runs this whole loop on open data in the browser.
Can I do OSINT with free satellite imagery?
Yes, for a large share of OSINT work. Open imagery — Sentinel-2 optical (~10 m) and Sentinel-1 SAR — resolves regional change such as flooding, fire scars, large construction, and vessel activity, and it is openly licensed so you can publish it with attribution. Identifying individual objects like specific vehicles or aircraft generally needs sub-meter commercial imagery, which you would source separately. Off-Nadir Delta is built on open Sentinel-class data with a free tier.
How do I find where to look in the first place?
Event data drives the area of interest. The Watchfloor surfaces geolocated events from global news media as they are reported, and Delta Agent turns a question into a brief that points you to the location and date worth imaging. Plain imagery viewers have no concept that "an event happened here," so they leave the where-to-look problem entirely to you.
Optical or SAR — which should I use for an event?
Use SAR (Sentinel-1) when the scene is cloudy or at night, or to detect vessels and structural change — radar provides its own illumination and sees through cloud. Use optical (Sentinel-2) for visual confirmation in clear daylight. Delta Agent recommends optical vs SAR for each event automatically, so you do not reach for an optical image of a cloudy scene.
Is this legal and ethical for OSINT?
Off-Nadir Delta uses only public, open sources — open event data and openly licensed satellite imagery — and its outputs cite their sources. It is intended for situational awareness, not for tracking or targeting individuals. Open data (Sentinel, Landsat, NASA) is broadly reusable with attribution, which is what makes it suitable for published investigations.
Do I need GIS software or coding?
No. Off-Nadir Delta runs entirely in the browser with no GIS software, no scripting, and no API keys. You can browse the Watchfloor and explore without an account; a free account unlocks Delta Agent and saving your work.
