現在、Landsat 7のSLCセンサーの故障によって残ったストライプを除去する方法を探しています。ArcGISで「no data」のストライプを比較的迅速かつ簡単に埋める方法はありますか？<\/P>
<\/P>
2002年から2013年の間に撮影されたシーンの土地分類にこれらの画像を使用する予定なので、他の衛星の画像を使うことはできません。<\/P>
どんな支援でも感謝します！<\/P><\/BODY><\/HTML>
Hi Laura, the last link is still working
gapfil_AG9x_10x.rar — RGhost — file sharing
Check the 2 pdfs if you have problems with the tool.
Here
EarthExplorer
you can download the new landsat v8 data for free.. You need only to register an account
I uploaded the free idl version of the tool. It's a x86 application, but is still good
external link here
MEGA
To start the tool, double click on frame_and_fill_win32.exe.
For more info read the read.txt file..
If you have access to the Spatial Analyst Extension, one possibility is to recalculate the No Data areas to a different value using CON:
Conditional Evaluation with Con
ArcGIS Help (10.2, 10.2.1, and 10.2.2)
Con (Spatial Analyst) tool
One caveat - doing so will universally change all No Data areas, so check to see if there are areas where No Data will still be appropriate. If that is the situation, there will be other process steps needed to limit the area that is recalculated.

Chris, your links go nowhere, Rebecca proposed how to fix them (can't find the link) or just use 10.3 links they are 99% the same as 10.2
I'll try using the 10.3 links from now on. Not sure why the 10.2 ones don't seem to work anymore....
If you have access to ENVI, the user contributed Landsat gapfill tool is very good at filling the gaps. The tool covers the three USGS gap fill methods:
The two image methods require two SLC-Off scenes, one to be filled and one to fill with. I try to stick to scenes from the previous or next cycle but that's not always possible due to cloud.
The 3rd method "two image local histogram matching" is the most computationally expensive, but produces by far the best results.
Before:
After local histogram matching and pansharpening:

Hi Nicola,
Thanks for your response. I am having trouble getting the SLC_off project toolbox into ArcGIS. Could you talk me through how to do it?
Regards,
Laura
Laura, you need the original mask image file to blend with the SLC_off image form the ETM+7 band. In the same way it work in Envi
Sorry maybe I wasn’t clear I can’t actually get the toolbox into ArcGIS using the download from the link you provided (SLC_off project.rar — RGhost — file sharing <https://community.esri.com/external-link.jspa?url=http://rghost.net/6zRRxJTpB> ) Do I need to save it in a particular place? And what is the process for adding it to the ArcGIS toolbox?
Thanks,
Could give me tool which remove lines of ETM image
Which is called Landsat toolboxfor arc10.8
