文摘
- •
Supraglacial lake bathymetry is feasible using only remotely-sensed data.
- •
Worldview-2's stereo capability offers great potential for supraglacial bathymetry.
- •
Error in lake volume estimation in our study was < 1%.
- •
20">Lake depths estimates had near zero bias and an accuracy of 0.4 m.
- •
25">Dual-channel depth-retrieval models performed better than single-channel methods.
