or <a href="/wiki/Astrophotography" title="Astrophotography">image</a> of a region of the <a href="/wiki/Sky" title="Sky">sky</a> (or of the whole sky) that lacks a specific observational target. Alternatively, an astronomical survey may comprise a set of images, spectra, or other observations of objects that share a common type or feature. Surveys are often restricted to one band of the <a href="/wiki/Electromagnetic_spectrum" title="Electromagnetic spectrum">electromagnetic spectrum</a> due to instrumental limitations, although multiwavelength surveys can be made by using multiple detectors, each sensitive to a different bandwidth.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">&#91;</span>1<span class="cite-bracket">&#93;</span></a></sup> </p><p>Surveys have generally been performed as part of the production of an <a href="/wiki/Astronomical_catalog" title="Astronomical catalog">astronomical catalog</a>. They may also search for <a href="/wiki/Transient_astronomical_event" class="mw-redirect" title="Transient astronomical event">transient astronomical events</a>.

In some cases, an astronomer interested in a particular object will find that survey images are sufficient to make new telescope time entirely unnecessary. </p><p>Surveys also help astronomers choose targets for closer study using larger, more powerful telescopes. If previous observations support a hypothesis, a telescope scheduling committee is more likely to approve new, more detailed observations to test it. </p><p>The wide scope of surveys makes them ideal for finding foreground objects that move, such as asteroids and comets. An astronomer can compare existing survey images to current observations to identify changes; this task can even be performed automatically using <a href="/wiki/Image_analysis" title="Image analysis">image analysis</a> software. </p><p>Besides science, these surveys also detect <a href="/wiki/Potentially_hazardous_object" title="Potentially hazardous object">potentially hazardous objects</a>, providing a service to <a href="/wiki/Spaceguard" title="Spaceguard">Spaceguard</a>. For example, the <a href="/wiki/Asteroid_Terrestrial-impact_Last_Alert_System" title="Asteroid Terrestrial-impact Last Alert System">Asteroid Terrestrial-impact Last Alert System</a> (ATLAS) system surveys the entire night sky every night and, like <a href="/wiki/NEOSTEL" title="NEOSTEL">NEOSTEL</a>, is intended to detect objects as they approach.
