Creating multiple subset tiles

You can create multiple subset files using the tiling feature on the Clipping/Subsetting window. In the Clipping/Subsetting window preview window, the bounding outline is replaced by a grid to help you divide the data into the number and size of tiles you want. After you have selected and prepared the data you want to work with, you access the tile output controls by clicking the Tile Output command button. You can choose from two tiling methods and you can control the amount of overlap between each file. When you process the data, Focus creates a new file based on each tile and the input data you selected.

  1. In the Clipping/Subsetting window, click Tile Output.
  2. In the Tile Definition area, choose one of the following options from the Definition Method list box:
    • Use tile size and overlap:creates tiles based on the size measurement values that you enter in the Tile Size X and Y boxes.
    • Use number of tiles and overlap: creates tiles based on the values you enter in the Number of Tiles X and Y boxes.
  3. Choose a unit of measure from the Units list box. The Geocoded option derives the tile coordinates from the input data. You can move and re-size the tile bounding grid to any location within the preview window.
  4. Enter values that represent the amount of overlap you want between each of your subset files in the Overlap X and Y boxes.
  5. Click Clip.
