文摘
- •
We monitor rivers and reservoirs based on airborne SAR/InSAR data.
- •
We extract digital elevation models (DEMs) from SAR/InSAR products.
- •
We present a novel approach for estimating water levels from DEMs.
- •
We propose a novel contour tracking algorithm to detect river margins.
- •
Our method is accurate and reliable for estimating water levels.
