RE: NEST on a stick

2012-01-25T14:51:47Z

This should be possible. You only need what is in the NEST installation folder. Any other folder such as the .nest and auxdata folders are created at runtime.

I'll package a plain zip file without installer for this purpose.

wind field estimation

2012-01-10T03:34:12Z

Hi all,

First of all, let me congratulate you for the great job you have been doing with NEST.

I've been using ENVISAT data and I'm interested in the wind field estimation file generated by NEST.
Example of one of the rows of these files:
<windFieldInfo lat="35.13" lon="-121.95" speed="8.6" dx="-21.21" dy="-425.47" ratio="0.72" />

Concerning these files 2 questions arise:
1-What are the units of dx and dy?
2-So far the ratio values have been pretty high, average=0.7.
Are these normal ratio values? Is there any known bug in calculation of ratio value?

Best Regards,
Ricardo Vicente

RE: ATI Support

2011-08-15T19:13:08Z

NEST version 4A-1.6 fails to read any ATI datasets, I get the same error as I mentioned to you before. Should I try version 4B beta?

RE: ATI Support

The reader should be able to read the product including the before and after acquisitions. It may be possible to run the coherence on it but other insar operators would require more work to handle it properly.

NEST cannot read TerraSAR-X ATI (Along-Track Interferometry) data currently. Any tool for that would be really great.

wind field estimation tool

2010-12-16T22:12:14Z

First of all, congratulations for the impressive work you guys have been doing.

An item to my wish list. In my opinion, the wind field estimation tool is far from ideal. Would be great if you could improve it, allowing us to really extract wind speed and direction. I have tried using an image with low wind speed conditions and it did not work satisfactory. Would be great to have a more robust tool to do this job.

Can Sandia SAR Data be supported

2010-11-28T12:33:22Z

hellow!
Can we imagine that NEST could support theSandia SAR Data?

Dear Antoine,

Do you have a description of the file format, metadata etc.

Best regards,

Hi Folks,

Can we imagine that NEST could support the Cassini RADAR data?
If not why?

Thank you

RE: command line/batch processing

2010-08-10T19:53:56Z

Indeed, the command line tool is not very user friendly. What it needs is better substitution of variables.

From the graph builder, create your graph and save it. Edit it in a text editor inserting variable for anything you want replaced at the command line.

For example:

1
2<node id="1-Read">
3 <operator>Read</operator>
4 <sources/>
5 <parameters class="com.bc.ceres.binding.dom.Xpp3DomElement">
6 <file>$file</file>
7 </parameters>
8 </node>

the from the command line you can substitute for that variable

gpt graph.xml -Pfile=c:\data\myfile.dim

Look in the NEST4A/commandline/ folder for examples.

I believe you can import a geometry from a shape file when a product is currently opened.
You can define a bitmask using that geometry from the bitmask manager or band arithmetic.

command line/batch processing

2010-07-27T09:42:50Z

Hello,
first of all thank you for the unvaluable work you do in the development of NEST.

second, I would like to add a couple of topics to the wishlist:

1) the ability to:
1.a) import a geometry
1.b) define a mask based on the imported geometry

2) some examples on using gpt.sh, even under linux: I could not find useful information in nest help or reading the .bat files. I tried to use my graphs, which work well from the graphical UI, but under gpt.sh they don't work: something is always not working.
for example, using this graph:

1) read a cosmo-sky-med image
2) apply land mask
3) write the result in beam-dimap

from UI is ok and results in a "target.dim" file with relative data directory in the input file directory.

I tried to run the graph from the command line, but it results in a warning and an error:

$> gpt.sh /path/to/graph.xml /path/to/file.h5 -t /path/to//target.dim

Range Normalization

2010-07-07T04:29:02Z

I'm just wondering about the possibility to get a "range normalization" which works over ocean for ASAR image?

RE: Ship detection Results to Shape file

2010-06-29T16:37:42Z

Yes, we're working on this. The ocean tools should produce Geometries which you can then run statistics on or use as ROI and export them to shape.

RE: Wishlist

2010-06-29T16:37:01Z

Thanks a lot M for the great feedback.

classification and dem from interferogram are already scheduled to be implemented within the next few months.
search options and .nest location should be available in the next release by June.
We'll examine the rest and see where they fit in.

Thanks

RE: polarimetric SAR

2010-06-29T16:34:54Z

We don't plan to add polarimetric processing. ESA's PolsarPro? software handles that. We will try to integrate better with PolsarPro? so that the tools of both software can be shared.

It would be nice to have some more tutorials, and some with more detail than those currently provided. Just trying to get my head around the relationship of projects, sessions, products, .beam, .dim etc. plus all the functionality is taking some time and trial and error. I have already screwed up several sessions along the way.
