Adds a new color map or
replaces an existing color map on a raster dataset.
1. Input Raster

add or replace a color map.
2. Input Template Raster (optional)
A raster dataset that
has a color map that you want to apply to the input raster dataset.
3. Input .clr or .act File (optional)

Batch Build Pyramids
Builds pyramids for
multiple raster datasets.
1. Input Raster Datasets
The raster datasets for
which you want to build raster pyramids.
Each input should have
more than 1024 rows and 1024 columns.
2. Pyramid levels (optional)
Choose the number of
reduced-resolution dataset layers that will be built. The default value is -1,
which will build full pyramids. A value of 0 will result in no pyramid levels.
3. Skip first level (optional)
Choose whether to skip the first pyramid level. Skipping the first level will take up slightly less disk space, but it will slow down performance at these scales.
- Unchecked—The first pyramid level will be built. This is the default.
- Checked—The first pyramid level will not be built.
4. Pyramid resampling technique (optional)
The resampling technique used to build your pyramids.
- NEAREST—The nearest neighbor resampling method uses the value of the closest cell to assign a value to the output cell when resampling. This is the default.
- BILINEAR—The bilinear interpolation resampling method determines the new value of a cell based on a weighted distance average of the four nearest input cell centers.
- CUBIC—The Cubic convolution resampling method determines the new value of a cell based on fitting a smooth curve through the 16 nearest input cell centers.
5. Pyramid compression type (optional)
The compression type to use when building the raster pyramids.
- DEFAULT—If the source data is compressed using a wavelet compression, it will build pyramids with the JPEG compression type; otherwise, LZ77 will be used. This is the default compression method.
- LZ77—The LZ77 compression algorithm will be used to build the pyramids. LZ77 can be used for any data type.
- JPEG—The JPEG compression algorithm to build pyramids. Only data that adheres to the JPEG compression specification can use this compression type. If JPEG is chosen, you can then set the compression quality.
- NONE—No compression will be used when building pyramids.
6. Compression quality (optional)
The compression quality
to use when pyramids are built with the JPEG compression method. The value must
be between 0 and 100. The values closer to 100 will produce a higher-quality
image, but the compression ratio will be lower.
7. Skip Existing (optional)
Specify whether to build pyramids only where they are missing or regenerate them even if they exist.
- Unchecked—Pyramids will be built even if they already exist. Therefore, existing pyramids will be overwritten. This is the default.
- Checked—Pyramids will only be built if they do not exist.
Batch Calculate Statistics
How to Batch Calculate
Statistics Tool in Arc Toolbox ArcMap ArcGIS??
Batch Calculate Statistics

Batch Calculate Statistics
Calculates statistics
for multiple raster datasets.
1. Input Raster Datasets
The input raster
datasets.
2. Number of columns to skip (optional)
The number of horizontal
pixels between samples.
A skip factor controls
the portion of the raster that is used when calculating the statistics. The
input value indicates the horizontal or vertical skip factor, where a value of
1 will use each pixel and a value of 2 will use every second pixel. The skip
factor can only range from 1 to the number of columns/rows in the raster.
The value must be
greater than zero and less than or equal to the number of columns in the raster.
The default is 1 or the last skip factor used.
The skip factors for
raster datasets stored in a file geodatabase or an enterprise geodatabase are
different. First, if the x and y skip factors are different, the smaller skip
factor will be used for both the x and y skip factors. Second, the skip factor
is related to the pyramid level that most closely fits the skip factor chosen.
If the skip factor value is not equal to the number of pixels in a pyramid
layer, the number is rounded down to the next pyramid level, and those
statistics are used.
3. Number of rows to skip (optional)
The number of vertical
pixels between samples.
A skip factor controls
the portion of the raster that is used when calculating the statistics. The
input value indicates the horizontal or vertical skip factor, where a value of
1 will use each pixel and a value of 2 will use every second pixel. The skip
factor can only range from 1 to the number of columns/rows in the raster.
The value must be
greater than zero and less than or equal to the number of rows in the raster.
The default is 1 or the last y skip factor used.

If the skip factor value is not equal to the number of pixels in a pyramid

4. Ignore values (optional)
The pixel values that
are not to be included in the statistics calculation.
The default is no value.
5. Skip Existing (optional)
Specify whether to calculate statistics only where they are missing or regenerate them even if they exist.
- Unchecked—Statistics will be calculated even if they already exist; therefore, existing statistics will be overwritten. This is the default.
- Checked—Statistics will only be calculated if they do not already exist.

Build Pyramids
Builds raster pyramids
for your raster dataset.
This tool can also be
used to delete pyramids. To delete pyramids, set the Pyramids Levels parameter
to 0.
1. Input Raster Dataset
The raster dataset for
which you want to build pyramids.
The input should have more
than 1,024 rows and 1,024 columns.
2. Pyramid levels (optional)
Choose the number of
reduced-resolution dataset layers that will be built. The default value is -1,
which will build full pyramids. A value of 0 will result in no pyramid levels.
To delete pyramids, set
the number of levels to 0.
The maximum number of
pyramid levels you can specify is 29. Any value that is 30 or higher will
revert to a value of -1, which will create a full set of pyramids.
3. Skip first level (optional)
Choose whether to skip the first pyramid level. Skipping the first level will take up slightly less disk space, but it will slow down performance at these scales.
- Unchecked—The first pyramid level will be built. This is the default.
- Checked—The first pyramid level will not be built.

- JPEG_YCbCr—A lossy compression using the luma (Y) and chroma (Cb and Cr) color space components.
- NONE—No compression will be used when building pyramids.
6. Compression quality (1-100) (optional)
The compression quality
to use when pyramids are built with the JPEG compression method. The value must
be between 0 and 100. The values closer to 100 will produce a higher-quality
image, but the compression ratio will be lower.
7. Skip Existing (optional)
