    I am willing to share with my new knowledge about Synthetic Aperture Radar applications in future. Stay tuned!

    Hello Two & Solution! Why can't my computer perform geometric correction? When I order the process, it stays in "writing target product" and does nothing. I am using a 4th generation core i7 and a 10th generation one. Greetings from Nicaragua!

      Hello Guillermo; Sorry for late response. I think that it can be related to the size of RAM, or a quality of Digital Elevation Model (DEM). My laptop has 16-GB RAM but at least 32-GB RAN recommended as I heard. A few time I didn't find any results with SRTM so chose another DEM.

    which version from ANACONDA, phyton and Sen2cor do you install? Please

      Greeting. I didn't apply to any python nor Sen2cor - only with SNAP 8.0 software for SAR processing.

    please make vedio on calculating refractive index on sar dem

      Quick googling but I can't find how to calculate refractive index from Synthetic Aperture Radar image. This journal paper showed how to retrieve refractive index from multispectral images - www.mdpi.com/2072-4292/9/4/313/htm

    hi, i have meet an error, Dimap header file failed to read, what does it mean?

    • @TWOandSolutions
      @TWOandSolutions  3 ปีที่แล้ว

      Thanks for your question. It sounds like an issue of different Sentinel 1A or 1B products at Level-1 SLC, or Level-1 GRD. It might be useful to look over the link on ESA website or step forum as following:
      - sentinels.copernicus.eu/web/sentinel/missions/sentinel-1/data-products
      - forum.step.esa.int/t/cant-open-safed-dim-files-in-snap-error-angle-is-too-high/4938

    hi two & solutions, i want to asking why my apllication snap cant open intensity or amplitude in bands? please answer my questions. Thankyou :)

      Hi Nikmah Fitria; I would suggest checking if you have Sentinel-1 raw data with EW_GRDM format. Secondly, on a step of Terrain Correction (TC), if your DEM covers sufficiently your Region of Interests. In third, please check a step including *Intensity_HH* - choose *Linear to/from dB*. Otherwise, you may find an answer from one of reference in the description of this TH-cam video ABOVE.

    Can we do moon"s analysis on it

    • @TWOandSolutions
      @TWOandSolutions  3 ปีที่แล้ว +1

      Yes or no. As long as we have a RADAR image collected from the Moon's surface, we could do data analysis. I didn't see a type of RADAR image on Moon rather than optical image to the public.

      It might be interesting for you - www.nasa.gov/mission_pages/Mini-RF/news/2009-01-16_radar_first_look.html It looks like no longer to access to ISRO/Chandrayaan mission website - www.isro.org/Chandrayaan
