<DIV>Hi All,</DIV>
<DIV> </DIV>
<DIV>I am trying to use an integer GRID to convert a portion of a raster DEM to NoData. My syntax is as follows:</DIV>
<DIV> </DIV>
<DIV>OutputDEM = setnull(IntegerGrid > 0, InputDEM)</DIV>
<DIV> </DIV>
<DIV>The map algebra statement executes but returns a GRID with all the cells equal to 0. The result is the same whether I use the tool or command line.</DIV>
<DIV> </DIV>
<DIV>Any ideas?</DIV>
<DIV> </DIV>
<DIV>Thanks, Greg</DIV>
