Randomized trial demonstrates effective monitoring of linear infrastructures, suggesting improved safety and efficiency.
Key Points
The study aims to develop a computationally efficient approach for monitoring spatial displacement gradients in linear infrastructures using SAR images.
Proposes a new approach utilizing known locations of linear infrastructure for estimating differential displacement velocities.
Evaluates the method using TerraSAR-X and Sentinel-1 images.
Assesses the sensitivity of grid size on root mean square error (RMSE).
Achieves a root mean square error (RMSE) of approximately 0.1 cm/year compared to conventional MTInSAR results.
Demonstrates effectiveness with grid sizes larger than 300 m, smoothing small variations.
Reports good agreement between estimated velocities and conventional results.
