QuestionPrimary fit

Event-time surface-water observation

For a buyer-selected place and time, NASA CMR provides spatial and temporal discovery and standing access to 30 m DSWx-HLS tiles whose WTR and BWTR layers classify open or partial surface water and whose metadata pins sensing time, processing time, product version, and software version. The mapping is limited to observed surface-water presence and must not be represented as flood anomaly, floodwater attribution, permanence, or water depth.

Surface water classification

CoverageGlobal

NASA CMR metadata gives the collection a near-worldwide bounding box from 84°S to 84°N across all longitudes. Polar areas outside that latitude range are excluded.

Access & termsFree

The cited public agency dataset, lookup, download, or API endpoint is directly available without an order, subscription, membership, or payment step. The standing route represented by this source is therefore free; any optional records services outside that route are not part of this classification.
