Label | Explanation | Data Type |
Mosaic Dataset | The mosaic dataset that you want to build overviews on. | Mosaic Layer |
Output Location (Optional) | The folder or geodatabase to store the overviews. | Workspace |
Extent from Dataset
(Optional) | A raster dataset or feature class to define the extent of the overviews. | Raster Layer; Feature Layer |
Extent (Optional) | Manually set the extent using the following minimum and maximum x and y coordinates. The mosaic dataset boundary will determine the extent of the overviews if you do not define an extent. | Envelope |
Pixel Size (Optional) | If you prefer not to use all the raster's pyramids, specify a base pixel size at which your overviews will be generated. The units for this parameter are the same as the spatial reference of the mosaic dataset. | Double |
Number Of Levels (Optional) | Specify the number of levels of overviews that you want to generate overviews. A value of -1 will determine an optimal value for you. | Long |
Number Of Rows (Optional) | Set the number of rows (in pixels) for each tile. Larger values will result in fewer, larger individual overviews, and increase the likelihood that you will need to regenerate lower level overviews. A smaller value will result in more, smaller files. | Long |
Number Of Columns (Optional) | Set the number of columns (in pixels) for each tile. Larger values will result in fewer, larger individual overviews, and increase the likelihood that you will need to regenerate lower level overviews. A smaller value will result in more, smaller files. | Long |
Overview Sampling Factor (Optional) | Set a ratio to determine the size of the next overview. For example, if the cell size of the first level is 10, and the overview factor is 3, then the next overview pixel size will be 30. | Long |
Force Overview Tiles (Optional) | Generate overviews at all levels, or only above existing pyramid levels.
| Boolean |
Resampling Method (Optional) | Choose an algorithm for aggregating pixel values in the overviews.
| String |
Compression Method (Optional) | Define the type of data compression to store the overview images.
| String |
Compression Quality (Optional) | Choose a value from 1 - 100. Higher values generate better quality outputs, but they create larger files. | Long |
