The UDS (extra-Galactic) covers an area of 0.77 square degrees within the XMM-LSS field (which is contained within the DXS) in JHK to a depth of K=23.0. This is the deepest near-infrared survey yet conducted over such an area of sky, with the aim of studying the formation and evolution of galaxies in

telescope in the
Southern hemisphere. It aims to cover 7500 square degrees of the Northern sky. Four particular areas of investigation for UKIDSS are: "the coolest and nearest brown dwarfs, high-redshift dusty starburst galaxies, elliptical galaxies and galaxy clusters at redshifts 1 <
222:
The DXS (extra-Galactic) covers an area of 35 square degrees in JK to a depth of K=21.0 with 5 square degrees also imaged in H. The survey fields are at high
Galactic latitudes with low extinction, and are chosen to overlap with deep observations made at other wavelengths.
191:. While the high Galactic latitudes covered by the LAS make it suitable for observations of sources outside the Milky Way, the survey also targets Galactic sources, incorporating a second pass in J to measure proper motions of nearby stars.
213:
The GCS (Galactic) covers an area of 1400 square degrees in JHK to a depth of K=18.7. The area is distributed over ten open star clusters with the aim of measuring the mass function in a variety of
Galactic environments.

Of the five surveys in UKIDSS, two are directed towards
Galactic targets and three are optimized for extra-Galactic observations. The surveys are described here in decreasing order of area. The letters refer to

Galactic Plane than is possible at optical wavelengths, due to absorption by material in the disk of the galaxy.
