TL;DR: Get started in minutes: 1) Sign up free, 2) Open the Watchfloor to see world events on one screen, 3) Ask Delta Agent what an event means, 4) On the Map, draw an area and search satellite imagery (Sentinel-1/2/VIIRS), 5) Upload your data or add reference layers, 6) Compare layers and monitor change over time. No GIS experience needed.
Getting Started Guide
Learn how to use Off-Nadir Delta in just a few minutes: monitor world events on the Watchfloor, ask Delta Agent what they mean, and look closer with satellite imagery on the Map. This guide walks through all three, in the order you would use them.
No prior experience with GIS or satellite data is required. Follow along and you will be reading the world — from live events to satellite imagery — in no time.
Before you begin: accounts & tokens
Browsing the Watchfloor needs no account. Create a free account (no credit card) to chat with Delta Agent and save your work. Actions that load satellite imagery or run AI analysis use tokens — check your balance in the header anytime.
Step 1 · Watchfloor
Monitor world events on the Watchfloor
Your daily global situational picture — free to browse, no account needed.
The Delta Watchfloor: geolocated world events on one screen, ranked by severity.
1Open the Watchfloor
- Open Watchfloor from the top navigation — no login required to browse
- See the latest geolocated geopolitical and security events worldwide (Delta Signals, distilled from global news media)
2Scan and filter the signals
- Events appear on the map and in the live feed, ranked by severity
- Filter by category or region to focus on what matters to you
- See exactly what changed since you last looked (paid plans)
3Scrub the timeline and save areas
- Use the timeline to look back through recent activity and understand how a situation built
- Save the areas you care about to your watchlist for fast daily checks
Tip: Browsing the live global picture is free and needs no account — start here to find where to look today.
Step 2 · Delta Agent
Ask Delta Agent what it means
An AI intelligence analyst that returns sourced, geolocated briefs.
Delta Agent: ask in plain language, get a citation-backed intelligence brief.
1Ask a question in plain language
- Open Delta Agent and type a question — e.g. "What is escalating right now?" or "What is happening near a place I care about?"
- A free account is required to chat; each question draws from your token balance
2Read the sourced brief
- Delta Agent reasons over live events with real GEOINT/OSINT tradecraft
- You get geolocated findings with citations and confidence-calibrated language
- It recommends which sensor (SAR or optical) and which area to image next
3Act on a finding
- Every finding has a one-click action that opens it on the Map
- Display the recommended imagery, run a deeper assessment, or set up monitoring
Tip: Not sure where to start? Ask Delta Agent for "the top imaging priorities right now".
Step 3 · Map
Look closer on the Map
A no-code satellite-imagery workbench — no GIS software, no API keys.
The Map: stack Sentinel-1 SAR, Sentinel-2 optical, and VIIRS, then analyze.
1Search and add imagery
- Pan, zoom, or search for a location, then draw a bounding box for your area of interest
- Choose a source: Sentinel-1 (SAR), Sentinel-2 (optical), or VIIRS (nighttime lights)
- Set a date range, search, and click a result to add the imagery to the map
2Visualize and compare
- Switch between True Color, False Color, and indices like NDVI in one click
- Stack images from different dates and adjust opacity to compare
- Upload your own GeoTIFF/GeoJSON and add reference layers for context
3Analyze
- Run change detection between two acquisitions to reveal exactly what changed
- Detect vessels in Sentinel-1 SAR — day or night, through cloud
- Monitor an area over time as a time series with ±2σ anomaly detection
Tip: Start at a lower zoom level to preview an area before zooming in — this saves tokens.
Quick Reference: satellite sources
Which source to reach for on the Map, depending on what you need to see.
Sentinel-1 (SAR)
- • Works day and night
- • Sees through clouds and smoke
- • Best for: floods, disasters, vessels, ice
- • Grayscale radar imagery
Sentinel-2 (Optical)
- • Requires clear skies
- • Natural color and false color options
- • Best for: vegetation, agriculture, urban
- • 10 m resolution
VIIRS (Nighttime Lights)
- • Captures light emissions at night
- • Daily global coverage
- • Best for: urbanization, power outages, economic activity
- • ~500 m resolution
