We’ve got incredible SAR capabilities - but still struggle to use public and commercial data together. I’ve decided to build a new tool called MultiRTC to help fix this.

🚀Excited to be giving a NASA Earthdata webinar tomorrow!
I'll be walking through how to explore the new OPERA DISP dataset via ASF’s Displacement Portal. It’s gonna be great!

Sentinel-1 orbit files are now available in the Registry of Open Data on AWS!
• Publicly available, no login required 🎉
• Less downtime, thanks to Amazon S3 🎊
• Accessible via a new s1_orbits Python library and standard S3 tools 🥳

So great to see @insar_11 using @Ak_Satellite's new Sentinel-1 burst products for landslide analyses! Our burst products are much smaller than full Sentinel-1 scenes, making them ideal for this type of analysis.

⚠️ Starting April 1st, users will be given an allotment of 10,000 credits per month instead of 1,000 jobs per month.
Each type of job will cost a different number of credits. Notably, now you will be able to run up to 10,000 Burst InSAR jobs per month, a 10x increase!

Excited about the release of burst InSAR at @Ak_Satellite! Burst-based workflows are faster, simpler, and I now use them exclusively in my own work.
Come by my poster at #AGU23 today to learn more!

🚨Sentinel-1 Burst InSAR now available in HyP3!🚨
These bite-sized interferograms are perfect for applications that analyze small areas, or that need perfectly overlapping interferograms!
