The aerial photographs below are examples of analog imagery (film) on the left compared to digital imagery (right). You can see the digital image is much sharper with greater contrast and color saturation. Click on the pictures to get a full screen comparison.
In addition to the visual advantages that digital imagery offers, the amount of imagery that a digital camera can store far surpasses film based analog cameras. This allows longer flights which cover more area with digital cameras. The digital data is easier to handle, ship, or transmit and readily suits image processing, enhancement, registration and integration with GIS.
