Transform - Tiles: Copy

The Copy template appears in the template list when a raster tile field, of type Tile, has been picked in the Transform pane.  The template provides numerous operators to extract or to compute pixel or tile characteristics.

 

Copy

Provides numerous operators to extract or to compute pixel or tile characteristics and to save to the specified Result destination, using the data type required and providing options for each operation.  Available operations include:

 

  • channel - Extract raster data from the given Channel and copy to the Result destination, creating a new image if desired from the result.
  • channel average - Report the average value for the given Channel for pixels in the tile. For example, if the image has a single channel with pixel values giving terrain elevation, this will report the average terrain elevation in the tile.
  • channel maximum -  Report the maximum value for the given Channel for pixels in the tile.  For example, if the image has a single channel with pixel values giving terrain elevation, this will report the maximum terrain elevation in the tile.
  • channel minimum - Report the minimum value for the given Channel for pixels in the tile.  For example, if the image has a single channel with pixel values giving terrain elevation, this will report the minimum terrain elevation in the tile.
  • channel std deviation - Report the standard deviation of values for the given Channel for pixels in the tile.
  • channel std deviation pop - Report the square root of the population variance of values for the given Channel for pixels in the tile.
  • channel sum - Report the sum of values for the given Channel for pixels in the tile.
  • channel variance - Report the sample variance of values for the given Channel for pixels in the tile.
  • channel variance pop - Report the population variance of values for the given Channel for pixels in the tile.
  • number of channels - Report the number of channels in the tile.
  • number of missing pixels - Report the number of NULL pixels in the tile.
  • number of pixels - Report the number of non-NULL pixels in the tile.
  • pixels - Copy tile pixels into the specified Result destination.
  • x size - Report the x size of the tile in number of pixels.  A 128x128 tile will have an x size of 128.
  • y size - Report the y size of the tile in number of pixels.  A 128x128 tile will have a y size of 128.

 

Launch the template by choosing a Tile field and then double-clicking the Copy template.  When the template launches we can specify options.

 

 

Copy : channel

Extract raster data from the given Channel and copy to the Result destination, creating a new image if desired from the result.

 

Copy : channel average

Report the average value for the given Channel for pixels in the tile. For example, if the image has a single channel with pixel values giving terrain elevation, this will report the average terrain elevation in the tile.

 

Copy : channel maximum

Report the maximum value for the given Channel for pixels in the tile.  For example, if the image has a single channel with pixel values giving terrain elevation, this will report the maximum terrain elevation in the tile.

 

Copy : channel minimum

Report the minimum value for the given Channel for pixels in the tile.  For example, if the image has a single channel with pixel values giving terrain elevation, this will report the minimum terrain elevation in the tile.

 

Copy : channel std deviation

Report the standard deviation of values for the given Channel for pixels in the tile.

 

Copy : channel std deviation pop

Report the square root of the population variance of values for the given Channel for pixels in the tile.

 

Copy : channel sum

Report the sum of values for the given Channel for pixels in the tile.

 

Copy : channel variance

Report the sample variance of values for the given Channel for pixels in the tile.

 

Copy : channel variance pop

Report the population variance of values for the given Channel for pixels in the tile.

 

Copy : number of channels

Report the number of channels in the tile.

 

Copy : number of missing pixels

Report the number of NULL pixels in the tile.

 

Copy : number of pixels

Report the number of non-NULL pixels in the tile.

 

Copy : pixels

Copy tile pixels into the specified Result destination.

 

Copy : x size

Report the x size of the tile in number of pixels.  A 128x128 tile will have an x size of 128.

 

Copy : y size

Report the y size of the tile in number of pixels.  A 128x128 tile will have a y size of 128.
