DDWIDirect Difference Water Index

WaterMultispectralCitation Rank #252

Summary

The Direct Difference Water Index (DDWI) is a water spectral index intended for multispectral sensing. It was introduced in 2022; its source is cited as Hazem Usama Abdelhady, Cary David Troy, Ayman Habib, & Raja Manish (2022). A Simple, Fully Automated Shoreline Detection Algorithm for High-Resolution Multi-Spectral Imagery. Remote Sensing, 14(3). https://doi.org/10.3390/rs14030557 .

Based on the latest citation data, this index is in the 20.06th percentile overall, ranking 252 out of 314 indices with citation data. Among the 51 indices published within two years of 2022, it ranks 20 (62.75th percentile). Within the water application domain, it is in the 43.75th percentile and ranks 19 out of 32 indices with citation data. Among the 12 similarly aged water indices, it ranks 6 (58.33th percentile).
