FAQ
All questions
What is TERRASENSE?
A satellite + vision-AI service that supports crop disaster loss assessment, built by MomentCube. It compares satellite images before and after a disaster to find damage-suspect fields and survey points, and carries them through to a draft report for the certified assessor.
Does it replace the loss assessment?
No. It is a satellite first screening of suspected damage. The loss rate and indemnity are confirmed by a certified assessor in the field.
Which satellites?
Optical Sentinel-2 (10 m) and radar Sentinel-1, free from the European Copernicus programme.
How are damage grades set?
By how far per-10 m NDVI dropped between Sentinel-2 images before and after the event, graded minor, moderate or severe, corrected with the crop growth curve and discounting normal harvest decline.
What about cloud?
Cloud cells are dropped and the next clear scene is used. Floods after rain and typhoons are found with radar, which sees through cloud.
How are survey points chosen?
Up to three of the worst-hit points and one healthy control per field, exported as CSV, GeoJSON and PDF.
Does the satellite identify the crop?
No. Paddy, upland or orchard is chosen by the user.
Does it estimate yield?
No. No yield (t/ha), shipping dates, official crop surveys or crop-insurance reviews.
Are parcel boundaries official?
No. SAM2 parcel candidates are not cadastral or official boundaries and are not for land-use or direct-payment reviews.
How much does it cost?
An annual subscription of $35,000 (KRW 48 million plus VAT in Korea) covering 10,000 ha, 240 growth screenings a year, disaster analysis, damage maps, survey points and a draft report.
Is field photo reading available?
The stage-2 vision-AI field survey for lodging, flooding and fruit drop is in preparation and rolls out during the pilot.
Which languages?
The interface switches between 17 languages, including English and Korean.
