http://gis.stackexchange.com/questions/129487/how-to-subtract-rasters-using-the-gdal-calculate-command
Is this what the OP is doing?

just want to know how to subtract two raster using gdal_calculate command? Or what is the proper way of subtracting using this? Any idea would be greatly appreciated.
Note: gdal_calc is different from gdal_calculate.py. The raster I am using have different dimensions.

Yes I really want to. Maybe because it's missing some command?A command which will make it execute? And it just call the ordinal date and echoed that is why it was displayed only on the screen.

This just tells me that the several weeks we have been helping, you have not bothered to learn or understand any of the code we have supplied you on this forum or the other forums we have helped you on. At this point you have no other option but to accept my offer to do this for you by providing the information I requested in my previous post.

We might as well turn this website into a "Sports Betting" site.  Then at least I could make some money for all my hard work.  I will take the over on 8 pages.

You are just like Vegas.  Stacking the odds in your favor.  You should consider switching jobs.

Not a bad idea...

Can you teach me more please?  I'm trying my best to understand the code you gave me. What should be answer to your question? What is the additional command to make the calculation execute instead of just displaying it on the screen? I can't understand codes that easy and immediately.

Show me the line of code that Foxidrive posted for you that runs your gdal_calculate command.

Show me the line of code that Foxidrive posted for you that runs your gdal_calculate command.

Code: [Select]

echo gdal_calculate --outfile=%out_path%\%%a --calc="((image1-image2))" --image2=%sample_path%\sample_file_!Month!.tif --image1=%in_path%\%%a --extent=INTERSECT

Code: [Select]

echo gdal_calculate --outfile=%out_path%\%%a --calc="((image1-image2))" --image2=%sample_path%\sample_file_!Month!.tif --image1=%in_path%\%%a --extent=INTERSECT

What is the first word in that line of code?

What is the first word on that line of code?

The first word is echo. It display a string of characters on screen.

So if you want your gdal_calculate command to execute, what do you think you would need to remove from that line of code to make gdal_calculate execute?

I think I would need to remove the echo to execute. Does echo really affect lines of code or command from executing whereas it just prints string of characters on screen?

BINGO!
