TerraglassSTAC API

Earth observation

Imagery that is ready when you are

Atmospherically corrected, cloud-masked, co-registered and tiled — so your first analysis is an analysis, not three weeks of preprocessing.

What analysis-ready means here

Surface reflectance

Atmospheric correction applied per scene with the aerosol retrieval documented, not a black box. Top-of-atmosphere is kept alongside if you disagree with our choices.

Cloud and shadow masks

Per-pixel probability, not a binary flag, so you can choose your own threshold. Validated against 41,000 hand-labelled chips.

Co-registered

Sub-pixel alignment across sensors and dates, so a time series is a time series rather than a slideshow with drift.

Cloud-optimised

COGs with internal tiling and overviews. Read a 200×200 pixel window from a 10,000×10,000 scene without downloading it.

STAC everywhere

STAC 1.0 with the EO, SAR and projection extensions. If your tooling speaks STAC, it already speaks to us.

Provenance kept

Every derived product records the processing baseline, the auxiliary data version and the software commit that made it.

Scale

What a real project moves

A crop-monitoring study over one European country, one growing season, Sentinel-2 only. This is not an unusual request — it is a Tuesday.

  • 1,240 scenes covering the area of interest
  • Six revisits per tile across the season
  • Surface reflectance plus masks: 4.1 TB
  • With SAR added for cloud-free coverage: 9.8 TB

Common questions

The source data is, and always will be — we do not resell it. You pay for the processing, the co-registration, the masks and the fact that you can pull a window instead of a scene.
