| Geographic Product Locations - Detailed | |
| Producing Daily Global Coverage? | True |
| Globally Extensible | True |
| Product Delivery Latency | Varies with flood AOI, currently as high as ~ 30 hours because products are only distributed once per day. This could be reduced to about 6 hours after last MODIS collection of the day (~1:30 local). |
| Data Type | Optical, Potential flood alert system |
| Associated Capacity Development Resources | None |
| Product Format | Currently email, working on automated file transfer |
| Archived | None |
| Tailored Service Available | None |
| License Type | very limited distribution for near term evaluation due to lack of maturity of product |
| Spatial Extent | Land surfaces from 60S to 70N |
| Spatial Scale | 24 km x 24 km areas containing potential floods. Working to reduce this to circles of varying radius containing potential floods |
| Caveats | False positives due to residual cloud shadow, terrain shadow, and imperfect masking of "normal" water |
| Frequency | Daily |
| Overpass Latency | TBD |
| Downlink Latency | TBD |
| Processing Latency | TBD |
| Impacted By Cloud Shadows | None |
| Impacted By Terrain Shadows | True |
| Status | In Development |
