The advent of large-format array cameras has heralded a new era for the previously unexplored submm region of the spectrum. Large-scale surveys are now becoming a reality and over the next few years several ambitious programs will be undertaken to study a whole range of galactic phenomenon, from the environments of star formation to the occurrence and diversity of cold debris disks. In this talk I will review the current and near-term survey plans by comparing and contrasting their scientific goals and capabilities. Currently underway are surveys of the Galactic Centre (GC) region using BoloCAM (CSO) and Laboca (APEX). Such surveys will investigate, for example, how massive stars form and how their evolution is controlled by the environment around them.
Deeper and wider surveys of the GC at shorter submm wavelengths are planned in the next few years using PACS and SPIRE (Herschel) and SCUBA-2 (JCMT). The JCMT is also planning a number of additional legacy-style surveys which include the giant molecular clouds in the Gould Belt to provide a complete census of all pre-stellar and proto- stellar sources within 500 pc of the Sun. Finally, there are ambitious plans to carry out a shallow "all-sky" submm survey to address issues such as the relationship of infrared dark clouds to star formation and galactic structure. Such a survey will provide the first submm "atlas" of the sky and will undoubtedly be an invaluable tool for the new generation interferometers such as ALMA.
