The town mosaics are available as a compressed MrSID gen 4 format. The extent of the town mosaics are defined by a rectangle that includes the town boundary. The rectangle extent was used to ensure that no part of any town would be missing. Also, image data must be a rectangular shape so instead of providing you with many black pixels that contained no information, you get a full rectangle of aerial imagery!
To see the extent of the town mosaic that you can download, mouse over Mosaic Extent in the Results window. The orange square outlines the rectangular extent of imagery in that town's mosaic.
