Tile Tutorial

In this tutorial, you'll create tiles from a single image.

1.In Adobe Photoshop, open Americas_mosaic.tif from the \Tutorial Data\Americas folder.

2.On the Geographic Imager panel, click the Tile button.

3.In the Tile dialog box, choose the By Number of Tiles option, and enter 3 into both the Horizontal and Vertical text boxes.

In the Destination frame, the total number of files that will be created is listed as 9.

4.In the Overlap frame, enter 5 into both Horizontal and Vertical text boxes. Ensure Pixels is chosen in the Units drop-down list.

This creates an overlap of 5 pixels for each adjacent image.

5.Choose Separate Row/Column Numbers from the Naming drop-down list.

Each image will contain the name of the original image plus a reference to the row and column to which it represents.

6.Choose World from the Reference File Format drop-down list.

7.Click OK.

8.Create a new Tiles directory to save the tile images in. In this case, use the default file name (Americas_mosaic_1_1.tif) and click Save.

9.When the TIFF Options dialog box appears, click OK to accept the default settings.

Any TIFF options are applied to all subsequent files (in this case, nine files). These options are good to use if you need to optimize or compress your TIFF images.

10.When the tile process is completed, navigate to the destination directory and view the tile images.

The naming separate row/column numbers format is appended to the file name: the tile America_mosaic_1_1.tif belongs in the first row and first column; America_mosaic_1_2.tif in the first row and second column; and America_mosaic_1_3.tif in the first row and third column, and so on.
