Last time, we talked about despeckling. Another popular workflow with GeoExpress 7 uses two new features: output tiling and decoding.

Lots of customers have massive SID images that they need to chop up into smaller tiles and decode out to TIFF. In prior versions of GeoExpress, you could use a series of command line tools to do this, but of course this was unwieldy.

Here’s how easy it is to do in GeoExpress 7:

1. Add the file(s) you want to work with to the Images tab of the job list.
2. Select Image Crop… from the Tools menu. The Image Crop dialog appears.
3. In the Output Tiling section, choose how many rows and columns you want to divide your image into and click OK.
4. Now, just choose “GeoTIFF” as your output format (use the drop-down menu on the main interface) and click Encode Selected Images.

In no time, you’ll have a series of GeoTIFF tiles created from your original SID image.
