Field notes on satellite change detection — how the detection model works, what Sentinel-2's 10 m resolution can and cannot resolve, why independent corroboration matters for alert precision, and how teams use satellite monitoring for ESG reporting, forestry and construction oversight.
- Getting Started With TerrAlert: What You Need to Know
A practical first-day guide: what TerrAlert is, who it's for, how to pick a plan, how to set up your first area, and where to get help.
- How TerrAlert Works: A Simple Guide
A plain walkthrough of what TerrAlert actually does, end to end, from drawing an area on a map to receiving an alert, describing only functionality that exists today.
- Why Clear Information Matters During Important Decisions
Ambiguous or overstated information costs more than it seems, especially when a decision has real consequences. This is about why plain, precisely-scoped information beats an impressive-sounding but vague claim.
- Satellite Detection vs. Manual Site Visits: What's the Difference?
Neither approach is strictly better. They have different strengths. This compares satellite-based monitoring against physically visiting a site, honestly, including where a site visit still wins.
- How to Choose the Right Detection and Monitoring System
A buyer's checklist: the questions that actually separate a reliable monitoring system from an impressive-sounding one, covering cost, accuracy claims, support, security and integration.
- How Fast Are Satellite Alerts, Really? Explained in Simple Words
'Real-time' gets used loosely in satellite monitoring marketing. This is a plain, honest walkthrough of the actual delay between a change happening on the ground and an alert reaching you, and why it is measured in days, not minutes.
- Understanding False Alarms: Why Accuracy and Context Matter
Every detection system makes two kinds of mistakes, false alarms and missed events, and they trade off against each other. This explains both, and why corroborating a finding against an independent source is the most reliable way to reduce false alarms without just going quiet instead.
- How Organizations Can Build a Better Monitoring Strategy
Practical, non-vendor-specific steps for deciding what to monitor, how often, and how to make sure alerts actually lead to action instead of getting lost.
- From Data to Action: How Detection Systems Support Better Decisions
A satellite pass, by itself, decides nothing. This is the full chain, from raw data to a human decision, and where each link can break.
- Too Much Data? How Monitoring Systems Help You Find What Matters
There is more satellite imagery available today than any team could review by hand. This is about how automated monitoring turns an unmanageable volume of data into a short, relevant list.
- What Makes a Good Alert System?
Reliability, speed and clarity are the three things that separate an alert system people actually trust from one they learn to ignore. Here's what each one means in practice.
- How Maps and Satellite Data Help Us Understand What Is Happening on the Ground
Raw satellite imagery is just pixels. This piece explains the steps, from a picture to a map to an insight, that turn a satellite pass into something a person can actually use to understand a place.
- What Is Geospatial Data? A Simple Guide
Geospatial data is just information tied to a place on Earth. This guide explains the basic building blocks, coordinates, polygons, pixels and layers, in plain language.
- How to Spot Important Changes Before They Become Bigger Problems
A practical look at why catching a small change early is usually cheaper and easier than dealing with the large problem it grows into, and how to set up monitoring that actually catches it.
- What Is Satellite Monitoring and How Does It Work?
A beginner's guide to how satellites see the ground, why clouds are the biggest obstacle, and what 'resolution' actually means for what you can and cannot see.
- How Early Alerts Help People Make Better Decisions
Why finding out about a change a week sooner is usually worth more than finding out with perfect precision, and where that trade-off breaks down.
- What Is a Change Detection System and Why Does It Matter?
A plain-language explanation of change detection: comparing two pictures of the same place, taken at different times, to find what's different, and why that simple idea matters for anyone who cannot visit a place often enough.
