Eliminando franjas de las imágenes Landsat 7 SLC OFF

LauraDoughty

<\/HEAD>

Actualmente estoy tratando de encontrar una manera de eliminar las franjas dejadas por el mal funcionamiento del sensor SLC en Landsat 7. ¿Existe una forma relativamente rápida y sencilla de rellenar las franjas de 'sin datos' en ArcGIS? <\/P>

<\/P>

Utilizaré las imágenes para la clasificación de tierras en escenas tomadas entre 2002 y 2013, por lo que usar imágenes de otros satélites no es una opción.<\/P>

<\/P>

¡Agradecería cualquier ayuda!<\/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

ArcGIS Help (10.2, 10.2.1, and 10.2.2)

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

ChrisDonohue__GISP

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:

single image triangulation interpolation
two image global histogram matching
two image local histogram matching

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,

Laura

Could give me tool which remove lines of ETM image

Which is called Landsat toolboxfor arc10.8
