The Mosaic Generation module creates a series of output files in the specified output folder, depending on the specified options. For example, if you specified tiled output, the output folder will contain the mosaicked result in a series of tile files. The file names for the tiles are generated automatically.
In the specified output folder, the Mosaic Generation module also creates a definition folder containing a mosaic-definition file and a polygon-vector file.
Like the Mosaic Preparation module , the Mosaic Generation module can detect voids to help you assess the quality of the mosaic. A void is considered an area in the output image tiles where the pixels are NoData values. To make sure large areas around the edges of mosaics are not included, any cluster of void pixels which add up to greater than 100,000 pixels are not included by default. If voids are found, a warning message will display in the mosaic-generation child job.
Additionally, a file named <tile_ID>_Voids.pix is created with a polygon layer indicating the voids for that mosaic tile. All such void files are combined into a single file, MergedVoidFiles.pix .
If necessary, you can turn off void generation by opening the settings.py file in a text editor, and then changing the value of mosgenFindVoids from True to False , as shown in the following example:
You will find the settings file in the %PROHOME%\exe\PGS\config folder of your CATALYST Enterprise installation.
