Con
Performs a conditional
if/else evaluation on each of the input cells of an input raster.
1. Input conditional raster
Input raster
representing the true or false result of the desired condition.
It can be of integer or
floating point type.
2. Expression (optional)
A logical expression
that determines which of the input cells are to be true or false.
The Expression follows
the general form of an SQL expression. It can be entered directly, for example,
VALUE > 100. To use a text attribute field, use single quotes around the
values, for example, landuse = 'urban'. The expression can also be created in
the Query Builder dialog box that results from clicking on the SQL button.
3. Input true raster or constant value
The input whose values
will be used as the output cell values if the condition is true.
It can be an integer or
a floating point raster, or a constant value.
4. Input false raster or constant value (optional)
The input whose values
will be used as the output cell values if the condition is false.
It can be an integer or
a floating point raster, or a constant value.
5. Output raster
The output raster.

Pick
The value from a
position raster is used to determine from which raster in a list of input
rasters the output cell value will be obtained.
1. Input position raster
Input raster defining
the position of the raster to use for the output value.
The input can be an
integer or float raster.
2. Input rasters or constant values
The list of inputs from
which the output value will be selected.
The inputs can be
integer or float rasters. A number can also be used as an input.
Set Null Tool

Path to access the tool
:
Set Null Tool, Conditional Toolset, Spatial Analyst Tools Toolbox
Set Null
Set Null sets identified
cell locations to NoData based on a specified criteria. It returns NoData if a
conditional evaluation is true, and returns the value specified by another
raster if it is false.
1. Input conditional raster
Input raster
representing the true or false result of the desired condition.
It can be of integer or
floating point type.
2. Expression (optional)
A logical expression that
determines which of the input cells are to be true or false.
The Expression follows
the general form of an SQL expression. It can be entered directly, for example,
VALUE > 100. To use a text attribute field, use single quotes around the
values, for example, landuse = 'urban'. The expression can also be created in
the Query Builder dialog box that results from clicking on the SQL button.
3. Input false raster or constant value
The input whose values
will be used as the output cell values if the condition is false.
It can be an integer or
a floating point raster, or a constant value.
4. Output raster
The output raster.
If the conditional evaluation is true, NoData is returned. If false, the value of the second input raster is returned.
