Off-Nadir Delta is a real-time event and geospatial intelligence platform that decides what is worth observing. Disasters, conflict, environmental change, and infrastructure failures unfold worldwide every day, but the signals are scattered across news, open data, and satellite imagery — and reading them takes expertise and time. Off-Nadir Delta combines an AI analyst, maps, satellite data, and open sources to explore, visualize, and prioritize geographic events, and to answer the questions that precede any imagery spend: can a satellite settle this, is free Sentinel-class data enough or does it need commercial tasking, and when can the place next be imaged. Factual claims link to their sources, judgments are labelled as judgments rather than facts, and each brief reports its own citation coverage — naming any claim that lacks a source — instead of producing an assessment anyway. There are three ways to look, distinguished by scope: Delta Watchfloor (everywhere, today — today's prioritized picture of global risk, so you know where to look now), Delta Map (one place, right now — verify an event from space with Sentinel-1 C-band SAR, NISAR L-band SAR, Sentinel-2 optical, VIIRS nighttime lights, and NASA FIRMS active fires, no GIS software required), and Delta Monitor (one place, over time — fix an area, pick what to count such as ships alongside a berth, burned area or water extent, and every new Sentinel-1 or Sentinel-2 acquisition over it is measured automatically, with unusual readings flagged against the history). And two ways to be told: Delta Agent (an AI analyst that explains what happened and why it matters, and recommends which satellite sensor and area to image next) and Delta Reports (a written daily assessment with Key Judgments, calibrated confidence, and an outlook). Built for OSINT, geopolitical-risk, and satellite-intelligence analysts, and for developers integrating live signals and briefs through the API and MCP. Also applicable to emergency management, media, enterprise-risk, and research workflows. No intelligence background required. Free tier available.
