thank you for the response,
I would like to know if there is any restriction on publishing the contents of S- 1A images in the international journals
2nd query is
can I know Sentinel pass dates for the coming days of March and April month
thank you
Hi, for your second query, I suggest you look at the planning for S1-A and S1-B available via https://sentinel.esa.int/web/sentinel/missions/sentinel-1/observation-scenario/acquisition-segments. You will need to download the latest kml files and use with Google Earth - as the screenshot below shows, the next acquisition over your site is on 31st March.
hi
displaying Sentinel 1A images using SNAP takes long time ( more than 30 minutes)
how to speed up the process
what are the minimum work station requirements to process S1 and s2 images using SNAP
I strongly recommend at least to use SSD for usage (then, you can use HDD for storage). Also I recommend at least 16Go RAM. In terms of CPU, the stronger the better but CPU is not really a bottleneck of SNAP operation whereas lack of RAM clearly prevents SNAP from using some functionalities.
Hi
thank you for earlier responses
what is velocity of the Sentinel 1A satellite/sensor
Is it possible to obtain information on the slant range of every pixel of S-1A , IW, GRD image using SNAP tool
kindly guide
thank you
sir,
can we successfully coregister two S-1a, IW SAR images using SNAP
kindly guide
You can use the S1 TOPS Coregistration which contains all necessary steps but it allows to only select one swath in the Split tab. So you have to do this for all three swaths and then apply S1 TOPS Merge.
This entire graph takes quite much resouces, so you can also perform the single steps individually.
In any way, you need to apply S1 Deburst to later joint the single bursts of your swath after the coregistration.
As @ABraun explains to you and also, please take a look at this tutorial from Show Room, for more details.
thk you for response sir,
The sentinel 1A data for the year 2018 of the loctaion: latitude 12 deg and longitude 77 degree
has become offline . what is the way we can get access to data of the year 2017 and 2018 for all months
kindly guide
You can request them to be online one at a time (with a single user).
Alternatives are Alaska facilites of NASA, they work with Amazon and normally are not offline.
It happened to me this week to get data from NASA as from scihub takes an non-specific amount of time to get data online, without the chance to get any notification.
So options are:
ALASKA Facilities: https://search.asf.alaska.edu/#/
PEP-CNES:https://peps.cnes.fr/
SciHub : https://scihub.copernicus.eu
DIAS (creodias, sobloo, mundi, onda)
each of them with their pro and cons.
I hope this helps
Make your choice!
as mentioned by @mdelgado Alaska Facility has all the data online - its also very easy to search for the same frame in certain period and with certain time span - in your case 2017-2018 every month
Thk you for the response
could you clarify the following
thk u
sir,
kindly clarify the following error
if your product was acquired within the last two weeks, no precise orbit files are ready to download yet. Is this the case?
Hello ALL,
How could we calculate the RCS for a Radarsat 2 data??
Thanks in Advance
Thank you Sir, Is there any alternate method. Like doing it manually.
please check chapter 7 of this document
To clarify: You mean that calibration is currently broken in the latest version of the toolbox, not that it’s generically unsupported for RADARSAT-2, correct?
I have to admit I never actually validated the results myself, but the toolbox was previously capable of supposedly calibrating typical RADARSAT-2 products
