<DIV><FONT face=Arial size=2><SPAN class=098430017-15082008>I used the
geostatistical analyst extension to do some ordinary kriging of precipitation
data so I can then block krige the predicted rainfall for specific
watersheds. After the geostatistical layer is produced of predicted
rainfall I then do the following steps to obtain the rainfall predictions in the
watersheds of interest:</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=098430017-15082008>1. Right-click
on the geostatistical layer then properties then symbology tab and select
grid.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=098430017-15082008>2. Then I
select the geostatistical layer again, do data export to
raster.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=098430017-15082008>3. I then use
the spatial analyst to do zonal statistics on that raster
data.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=098430017-15082008></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=098430017-15082008>Under the symbology
tab, there are options of setting number of cells and cell size and number of
predictions in each cell. Also doing the data export raster step there are
options to set the number of rows, columns, and cell size, and to set block
interpolation. Does anyone have any advice, experience, or references as
to how to decide what the options should be set to under the symbology tab,
step 1, and the export to raster, step 2?</SPAN></FONT></DIV>
