Let’s take a look at different datasets with help of some Visualizations. The two datasets used are -

  1. AVISO GDR
  2. ALES OpenADB coastal retracked from Technical University of Munich (TUM)

Learning Rabbit Hole

I find myself chasing after the next best thing: data structures and algorithms, Linux, Julia, signal processing, etc… The accessibility to learning content online and the lectures/tutorials on YouTube provide an instant dopamine hit from learning new stuff.

Troubleshooting and Understanding

I had been struggling with the InSAR processing using SNAP for quite some time. There is always one cryptic message after another. The one that halted my progress was related to topographic phase removal. There was an issue with downloading the EGM96 model. I wondered why one requires a geoid model when I already have DEM for phase removal.

Before joining IIT Kanpur, I only knew about Prof. Dr. Bharat Lohani from his Surveying NPTEL course (the best Surveying course to date on the Internet) and his company GeoKno’s pioneering work in LiDAR technology. My reason for staying is my newfound interest in the field of Geodesy.

Orbit Corrections in SNAP

2 minute read

There’s a pretty common issue while performing orbit correction in ESA-SNAP. There’s a simple way to pre-download the required orbit files:

  1. All the files one at a time (bulk)
  2. As per the requirement.
