Decline
Use of photographic plates has declined significantly since the early 1980s, replaced by charge-coupled devices (CCD). CCD cameras have several benefits over glass plates, including high efficiency, linear light response, and simplified image acquisition and processing. However, even the largest CCD formats (e.g., 8192x8192 pixels) still do not have the detecting area and resolution of most photographic plates, which has forced modern survey cameras to use large CCD arrays to obtain the same coverage.
