You have to make sure that the output raster allows for NoData values. It might also depend on the format of the export. You&#039;re safe to go with GeoTIFF. But if you export as a JPG, then it won&#039;t allow you to have export a clip raster with null values.]]></description>

					<description><![CDATA[After completing steps 1-5 of option 2: Clip Raster with Raster Functions, I attempted step 6, but the raster that was exported didn&#039;t honor to clip from the previous steps. I repeated the process a couple of times with the same result. Do you have any ideas as to why that might be? Thank you in advance!]]></description>

Hard to say without seeing the data.

But my guess is that it sounds like your original raster was Esri grid format. The raster table was a value attribute table (VAT).  

After you clip the raster and export, did you try running the tool &quot;build raster value attribute table&quot;.  Make sure you backup your data before you test it out. If it&#039;s a GeoTIF, then this format does not support VAT (at least from what I can remember).

So, you might want to try using the clip tool and keep the same format of your original raster. If you want to use the Image Analysis toolbar, there&#039;s a drop-down list where you can pick the format. 

If you could fimd the original raster format, that would be helpful. Then, you can export with that same format.

Any more information would be helpful for me. Let me know how things work out.]]></description>

					<description><![CDATA[I am pretty new to rasters and I have been stumbling around for a while so I was glad to find this post, but I am still having a problem.

I don&#039;t actually know the format of my input raster, but it had float values attached to some attribute data. My output raster had no attribute data when I clipped using the image analyzer. Is this because I outputted as TIFF or was there a box somewhere that I needed to check and didn&#039;t?

Thanks]]></description>

					<description><![CDATA[In reply to &lt;a href=&quot;https://gisgeography.com/clip-rasters-arcgis-polygon-boundary/#comment-17925&quot;&gt;kerry holmberg&lt;/a&gt;.

Are the pixels actually shifting?  For example, the input raster will have different values compared to the output raster in different locations of the raster?  Or is the shift associated with how/where the shapefile is clipping the raster?

If you were to resample your raster to a finer resolution and then clip the raster, what would be the result? Would there still be a shift?

Is the shapefile used to clip the input raster in the same coordinate system?

Sorry, but I&#039;m a bit confused with the question]]></description>

					<description><![CDATA[Would you please address the cell shift that Adam mentioned?  All my rasters that I clipped with a shapefile have a slight shift right.  Is there a way to avoid this?]]></description>

					<description><![CDATA[I wish Split Raster worked.  Tried it on 10.3 and 10.5.  Empty folder resulted.  Maybe a file size issue?  Inputs were source_dem, output folder, output base name, split method of polygon features, output format tiff (and ENVI, and GRID), Resampling nearest, split polygon feature class was a ~200 feature polygon shape file, other options were set to units:meters, cellsize specified same as imput DEM, and no data -9999.  The output folder was empty on every try.]]></description>
