UKIDSS is a set of five surveys. The areas and 5-sigma depths are as follows:

1. Large Area Survey (LAS)4000 sq. degs K=18.4extraGalactic
2. Galactic Plane Survey (GPS)1800 sq. degs K=19.0Galactic
3. Galactic Clusters Survey (GCS)1400 sq. degs K=18.7Galactic
4. Deep Extragalactic Survey (DXS)35 sq. degs K=21.0extraGalactic
5. Ultra Deep Survey (UDS)0.77 sq. degs K=23.0extraGalactic

The surveys will use 1000 nights of UKIRT time over 7 years, beginning in April 2005. The pages for each survey provide details of the filters, depths, areas, and targets. Each page summarises the overall 7-year plan as well as the plan for the first 2 years. The 7-year plans may change somewhat as the surveys progress. The 2-year plans have been worked up in detail and are now essentially fixed. The figure below shows the 7-year UKIDSS sky coverage.
