- Explanation of the interfaces (Logical
Tools):
 |
| Logical Tools |
- Boolean and: Performs a Boolean and operation on the cell values of two input rasters.
- Boolean or: Performs a Boolean or operation on the cell values of two input rasters.
- Boolean XOr: Performs a Boolean eXclusive or operation on the cell values of two input rasters.
- Combinatorial And: Performs a Combinatorial And operation on the cell values of two input rasters.
- Combinatorial Or: Performs a Combinatorial Or operation on the cell values of two input rasters.
- Combinatorial XOr: Performs a Combinatorial exclusive or operation on the cell values of two input rasters.
- Diff: Determines which values from the first input are logically different from the values of the second input on a cell-by-cell basis.
- Equal To: Performs a Relational equal-to operation on two inputs on a cell-by-cell basis.
- Greater Than: Performs a Relational greater-than operation on two inputs on a cell-by-cell basis.
- Greater Than Equal: Performs a Relational greater-than-or-equal-to operation on two inputs on a cell-by-cell basis.
- Less Than: Performs a Relational less-than operation on two inputs on a cell-by-cell basis.
- Less Than Equal: Performs a Relational less-than-or-equal-to operation on two inputs on a cell-by-cell basis.
- Not Equal: Performs a Relational not-equal-to operation on two inputs on a cell-by-cell basis.
- Over: For the cell values in the first input that are not 0, the output value will be that of the first input. Where the cell values are 0, the output will be that of the second input raster.
Input raster or constant value 1
The first input to use
in this bitwise operation.
A number can be used as
an input for this parameter, provided a raster is specified for the other
parameter. To be able to specify a number for both inputs, the cell size and
extent must first be set in the environment.
Input raster or constant value 2
The second input to use
in this bitwise operation.
A number can be used as
an input for this parameter, provided a raster is specified for the other
parameter. To be able to specify a number for both inputs, the cell size and
extent must first be set in the environment.
Output raster
The output raster.
The cell values are the
result of a Bitwise eXclusive Or operation on the two inputs.
- Explanation of the tool interface Boolean Not
 |
| Boolean Not |
Boolean Not: Performs a Boolean Not (complement) operation on the cell values of the input raster.
1. Input raster or constant value
The input raster on
which to perform the Bitwise Not (complement) operation.
A number can be used as
an input for this parameter, provided a raster is specified for the other
parameter. To be able to specify a number for both inputs, the cell size and
extent must first be set in the environment.
2. Output raster
The output raster.
The cell values are the result of a Bitwise Not operation on the input.
- Explanation of the tool interface InList
 |
| InList Tool |
InList: Determines which
values from the first input are contained in a set of other inputs, on a cell-by-cell
basis.
For each cell, if the
value of the first input raster is found in any of the list of other inputs,
that value will be assigned to the output raster. If it is not found, the
output cell will be NoData.
1. Input raster or constant value
The input raster whose
values will be looked for in the input list.
A number can be used as
an input for this parameter, provided a raster is specified for the other
parameter. To be able to specify a number for both inputs, the cell size and
extent must first be set in the environment.
2. Input raster or constant values
A list of input rasters
in which the cell values from the first input will be looked for.
A number can be used as
an input for this parameter, provided a raster is specified for the other
parameter. To be able to specify a number for both inputs, the cell size and
extent must first be set in the environment.
3. Output raster
The output raster.
- Explanation of the tool interface Is Null
 |
| Is Null Tool |
Is Null: Determines
which values from the input raster are NoData on a cell-by-cell basis.
1. Input raster
The input raster being
tested to identify the cells that are NoData (null).
The input can be either
integer or floating-point type.
2. Output raster
The output raster.
The output identifies
with an integer value of 1 which cells in the input are NoData. If the input is
any other value, the output is 0.
- Explanation of the tool interface Test
 |
| Test Tool |
Test: Performs a Boolean evaluation of the input raster using a
logical expression.
1. Input raster
The input raster on
which the Boolean evaluation is performed, based on a logical expression.
2. Where clause
The logical expression
that will determine which input cells will return a value of true (1) and which
will be false (0).
The Where clause 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'. It can also be created in the Query
Builder dialog box that results from clicking on the SQL button.
3. Output raster
The output raster.
The output values will be either 0 or 1.
