Cell Statistics
Calculates a per-cell
statistic from multiple rasters.
The available statistics
are Majority, Maximum, Mean, Median, Minimum, Minority, Range, Standard
deviation, Sum, and Variety.
1. Input rasters or constant values
A list of input rasters
for which a statistic will be calculated for each cell within the Analysis
window.
A number can be used as
an input; however, the cell size and extent must first be set in the
environment.
2. Output raster
The output raster.
For each cell, the value
is determined by applying the specified statistic type to the input rasters at
that location.
3. Overlay statistic (optional)
Statistic type to be calculated.
- MEAN—Calculates the mean (average) of the inputs.
- MAJORITY—Determines the majority (value that occurs most often) of the inputs.
- MAXIMUM—Determines the maximum (largest value) of the inputs.
- MEDIAN—Calculates the median of the inputs.
- MINIMUM—Determines the minimum (smallest value) of the inputs.
- MINORITY—Determines the minority (value that occurs least often) of the inputs.
- RANGE—Calculates the range (difference between largest and smallest value) of the inputs.
- STD—Calculates the standard deviation of the inputs.
- SUM—Calculates the sum (total of all values) of the inputs.
- VARIETY—Calculates the variety (number of unique values) of the inputs.
The default statistic
type is Mean.
4. Ignore NoData in calculations (optional)
Denotes whether NoData values are ignored by the statistic calculation.
- Checked—At the processing cell location, if any of the input rasters has NoData, then that NoData value will be ignored. The statistics will be computed by only considering the cells with valid data. This is the default.
- Unchecked—If the processing cell location for any of the input rasters is NoData, then the output for that cell will be NoData.

Path to access the tool
:
Combine Tool, Local Toolset, Spatial Analyst Tools Toolbox
Combine
Combines multiple
rasters so that a unique output value is assigned to each unique combination of
input values.
1. Input rasters
The list of input
rasters to be combined.
2. Output raster
The output combined
raster.
A unique integer value
is assigned to each unique combination of input values.
Equal to Frequency
How to use Equal to Frequency Tool in Arc Toolbox??

Equal to Frequency |
Path to access the tool
:
Equal
to Frequency Tool, Local Toolset, Spatial
Analyst Tools Toolbox
Equal to Frequency
Evaluates on a
cell-by-cell basis the number of times the values in a set of rasters are equal
to another raster.
1. Input value raster
For each cell location
in the input value raster, the number of occurrences (frequency) where a raster
in the input list has an equal value is counted.
2. Input rasters
The list of rasters that
will be compared against the value raster.
3. Output raster
The output raster.
For each cell in the
output raster, the value represents the number of times that the corresponding
cells in the list of rasters are the same as the value raster.
Greater Than Frequency

| Greater Than Frequency |
Path to access the tool
:
Greater
Than Frequency Tool, Local Toolset, Spatial
Analyst Tools Toolbox
Greater Than Frequency
Evaluates on a
cell-by-cell basis the number of times a set of rasters is greater than another
raster.
1. Input value raster
For each cell location
in the input value raster, the number of occurrences (frequency) where a raster
in the input list has a greater value is counted.
2. Input rasters
The list of rasters that
will be compared against the value raster.
3. Output raster
The output raster.
For each cell in the
output raster, the value represents the number of times that the corresponding
cells in the list of rasters is greater than the value raster.
Highest Position
How to use Highest Position Tool in Arc Toolbox??

| Highest Position |
Path to access the tool
:
Highest
Position Tool, Local Toolset, Spatial Analyst Tools Toolbox
Highest Position
Determines on a
cell-by-cell basis the position of the raster with the maximum value in a set
of rasters.
1. Input rasters or constant values
The list of input
rasters for which the position of the input with the highest value will be
determined.
A number can be used as
an input; however, the cell size and extent must first be set in the
environment.
2. Output raster
The output raster.
For each cell in the output raster, the value represents the position of the raster with the highest value.
