“Shift” tool has performance issue,

JamalNUMAN

I observed that the “Shift” tool has performance issue. Is it normal that a raster of 113 MB takes around 4 minutes in order to be shifted (-50000, -500000)? My machine is with 4 Cores X 64GB RAM

Is there any recommendation to increase the performance of this tool?

yes... time for some scripting to

read the *.pnw, rename them *.pnw_old,
get the appropriate lines containing the X, Y values,
do the math and
save the file out to a new copy so as to retain the old.

You wouldn't want to do this manually... even though it would be quicker than shifting.

Shift—Data Management toolbox | ArcGIS Desktop probably the same in arcmap

but anyway....

you didn't specify a file extension, so it isn't the shift that is taking a long time, but it is the conversion to an esri grid in the ZZ folder.

If you want to shift specify and output type by giving the raster an extension like *.tif... (ecw isn't on ArcGIS Pro's list of output types)

Many thanks for the input Dan.

I tried it with jpg extension. it took around 2 min and 15 sec.

I observed that as the ecw file (113 MB) is shifted with jpg extension, then ovr file is created with a size of 150 MB. This means that the 113 ecw file is ending up with 135 MB for jpg in addition to 150 MB for the ovr. This means that the size is tripled just to shift the raster!

try another format... esri usually recommends *.tif

JamalNUMAN

Now the size of the tif and ovr are much bigger: 1.5 GB for the tif and 350 MB for the ovr
