Hi everybody,

Is there any way how to write SQRT function in Band Arithemtic raster function ? or POW ?

I tried **, ^. But doesnt work.

Thanks.

In Band Arithmetic Function, the supported operators are -,+,/,*, and unary -.

Could you use Raster Calculator?

Expression (Choose any 1):  For Square Root

Power(RASTER,0.5)

Power(RASTER,(1.0/2.0))

SquareRoot(RASTER)

Or You may use Arithmetic (Raster Functions)

Thanks.

Now I see it in the documentation for User Defined function. What a pitty..other functions support also sqrt (for example MSAVI). We need raster function because we want to use together with published image service and dont want to use geoprocessing (which is much slower). Anyway thanks for pointing me to documentation.

You may use Calculator Function

** works in this function
