During the last decade, the techniques to generate digital elevation models (DEM) from SAR interferometry have been demonstrated and refined to a quasi-operational status using data from the ERS tandem mission. With this experience and an improved single-pass system concept, data from the Shuttle Radar Topography Mission (SRTM) acquired in 2000 have been used to produce a global DEM with unprec...

A raster grid with 1m spacing was created using simple kriging from LiDAR point clouds. The 2, 3, 4, 5, 8, and 10 m resolution were created from the original 1 m DEM using nearest neighbor resampling method. The derived DEM were used to study the sensitivity of terrain attributes while changing DEM resolution and possibly introduce a minimum required resolution for the study area. A variety of ...

The geodetic information of the terrain can be measured using remote sensing techniques such as photogrammetry, airborne laser scanner (ALS) and interferometric synthetic aperture radar (InSAR). They are considered to be more cost-effective and complementary to conventional ground-based surveying methods. Differential InSAR (DInSAR) can be further used to monitor the dynamic change of the terra...

The application of radar quantitative precipitation estimation (QPE) to hydrology and water quality models can be preferred to interpolated rainfall point measurements because of the wide coverage that radars can provide, together with a good spatio-temporal resolutions. Nonetheless, it is often limited by the proneness of radar QPE to a multitude of errors. Although radar errors have been wide...

This paper presents an effort to evaluate the generated digital elevation model (DEM) from active sensor onboard satellite of Sentinel-1A and aerial photos taken using unmanned vehicle (UAV). The objective is compare quality DEM review processes for disaster mitigation prevention plans application. radar data acquisition used in this study pair SLC-type data. interferogram processed coherence p...
