How this service works
Has this place been built on or cleared in the last 12 months? Sentinel-2 satellite change detection for any lat/lon: NDVI/NDBI deltas, change direction, confidence and the scene-by-scene evidence.
Output
Returns a JSON object with: whether change was detected (boolean), the direction of change (built-up, revegetated, none, or inconclusive), a confidence rating (high/medium/low), number of Sentinel-2 scenes used, recent and baseline NDVI/NDBI index snapshots, and an array of scene-by-scene evidence items supporting the determination.
Example use cases
Pre-acquisition land development check
“Before we close on this plot at 34.0522° N, 118.2437° W, can you check if any construction or clearing has happened there in the past 12 months and tell me how confident the satellite data is?”
Environmental deforestation monitoring
“I need to know if there's been any land clearing or loss of vegetation at the site at 51.5074° N, 0.1278° W in the last year — can you pull the Sentinel-2 change detection with the scene-by-scene evidence?”
Construction permit compliance verification
“Can you verify whether the site at 40.7128° N, 74.0060° W shows signs of recent built-up activity or soil disturbance over the last 12 months, and flag if the change confidence is high?”
Technical details
Endpoint
GEThttps://sitepulse.waltsoft.net/v1/site?utm_source=zero.xyzWhen to prefer
Use SitePulse when you need a fast, per-coordinate answer about whether a specific site has undergone physical land-use change (construction, clearing, or revegetation) in the past year, backed by Sentinel-2 satellite evidence and confidence scoring. Prefer this over manual GIS workflows or generic satellite APIs when you need a structured, decision-ready output including change direction and scene evidence without needing to process raw imagery yourself.
Side effects
- Coordinate outside Sentinel-2 coverage area — limited or no scenes available
- Persistent cloud cover over the location reducing scene count and confidence
- Insufficient scenes over the 12-month window resulting in 'inconclusive' change direction
- Invalid or missing lat/lon parameter causing request error
- Low confidence result when spectral change is marginal or ambiguous
