Min function in Raster Calculator

PascalPiquemal — Wed, 11 Aug 2010 12:36:08 GMT

Hi,

Min function seems not work on 10 like it was on 9.3

min("a", "b") lead to an 000539 error.

Same rasters on 9.3 give good results.

Any idea ??

Hi Pascal,

Lowest Postion describes the position of the inputs with the lowest value, hence order of inputs is relevant. What you want is Cell Statistics with the Minimum statistic type. Order of inputs is irrelevant and calculates the minimum (smallest value) of the inputs. There is no need to have Min and Cell Statistics with the Min option since they are essentially the same. The toolset was cleaned up in 10.

Cell Statistics

Best Regards,
Eric

While you may have "cleaned up" the toolset, taking out the GRID functionality from raster calculator is a huge step back in the wrong direction.
