What it does

The simplest way to explore satellite imagery. Off-Nadir Delta is a web-based platform that lets you access satellite data without any GIS software. Search Sentinel-1 (Radar) and Sentinel-2 (Optical) scenes in seconds. See the Earth as natural photos, highlight vegetation health, or see through clouds with radar—one click each. Compare images over time to spot changes in construction, agriculture, or land use. Built for curious minds who want to explore our planet without heavy tools.

Off-Nadir Delta turns scattered signals — news, open data, satellite imagery — into prioritized real-time event and geospatial intelligence: what happened, where to look, and what satellites can show. Built for OSINT and geopolitical-risk analysts — and anyone doing first response and situational awareness.

Real-time event and geospatial intelligence for OSINT, geopolitical risk, and GEOINT teams. Live, geolocated and source-linked world events—enriched with satellite observability and collection-ready recommendations: what to collect, where, and when. Use it in the web app, over the REST API, or straight from your AI agent through MCP. Seeing the event is easy. Knowing what you can prove—and what evidence is still missing—is the product. flood water extent at Kathmandu, Nepal; sentinel-1-sar + flood-mapping to map the inundated area against the pre-event shoreline.

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

    Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
