Create a mosaic with little to no seams using a list of map projected cubes
| Overview | Parameters | Example 1 |
Description
This program, noseam, creates a mosaic using an algorithm that minimizes seams.
The user will enter a text-based list of cubes that must be 1) in the same map projection
and 2) contain equivalent projection parameters such as PixelResolution, CenterLongitude, and
LatitudeSystem. More help is given in the Parameter Groups and with examples at the end of
this document.
To generate the mosaic, noseam uses the automos application. The FROMLIST and MATCHBANDBIN
parameters are taken from noseam and forwarded to automos as well as the remainder of the
parameters except with their default values. To learn more about automos parameters,
see the automos application documentation.

Files: FROMLIST
Description
A list of map projected cubes to mosaic seamlessly. The Mapping groups must match in order to mosaic the cubes.
| Type | filename |
|---|---|
| File Mode | input |
| Filter | *.txt *.lis *.lst |
Files: TO
Description
The resulting mosaic, which will be created from the listed cubes.
| Type | cube |
|---|---|
| File Mode | output |
| Filter | *.cub |
Filter Sizes: SAMPLES
Description
This is the total number of samples in the boxcar dimension applied using the highpass and lowpass filters. The number must be odd and cannot exceed twice the number of samples in the input cubes. The smaller the boxcar dimension, the more confined the filtered results are near the image seams, which will remain similar to the original mosaic. The larger the boxcar dimension, the greater the extent of the filter effects are beyond the seams.
| Type | integer |
|---|---|
| Minimum | 1 (inclusive) |
| Odd | This value must be an odd number |
Filter Sizes: LINES
Description
This is the total number of lines in the boxcar dimension applied using the highpass and lowpass filters. The number must be odd and cannot exceed twice the number of lines in the input cubes. The smaller the boxcar dimension, the more confined the filtered results are near the image seams, which will remain similar to the original mosaic. The larger the boxcar dimension, the greater the extent of the filter effects are beyond the seams.
| Type | integer |
|---|---|
| Minimum | 1 (inclusive) |
| Odd | This value must be an odd number |
BandBin Option: MATCHBANDBIN
Description
This option causes the application to fail if the input bandbin group does not match the mosaic bandbin group.
| Type | boolean |
|---|---|
| Default | TRUE |
Intermediate Data: REMOVETEMP
Description
Multiple cube images as well as lists are created during the production of the final seamless mosaic. If this parameter is changed to false, those temporary cubes and lists will not be destroyed.
If REMOVETEMP=NO:
- OriginalMosaic.cub - This file is the mosaic result (automos) of the input cubes listed in FROMLIST.
- LowpassMosaic.cub - This file is the low pass filter (samples x lines) applied to the OriginalMosaic.cub.
- HighpassMosaic.cub - This file is the mosaic result (automos) of the high pass filtered input cubes listed in FROMLIST.
- HighPassList.lis - This single column list contains the individual highpass filter image results and filenames.
- _highpass.cub - Every image in the fromlist will have a high pass filter (samples x lines) output result. This is the suffix filename appended the original input filenames.
- LowpassMosaic.cub + HighpassMosaic.cub = TO (noseam output filename)
| Type | boolean |
|---|---|
| Default | TRUE |
Example 1No Seam Result Description
This example shows how noseam works upon a small mosaic and
compares that result to an automos output.
Command Line
noseam FROMLIST=cubes.lis
TO=final.cub SAMPLES=73 LINES=73
Runs noseam with a 73x73 highpass filter and a 73x73 lowpass
filter.
