HI mapping at intermediate Galactic latitude (GHIGLS): deep Green Bank Telescope surveys of 21-cm line emission in 37 targeted fields (see the GHIGLS Data Repository).
The VLA Galactic Plane Survey (VGPS): A combined interferometer + single-dish survey of 21-cm (1420 MHz) line emission from neutral atomic hydrogen (HI) in the Galaxy (see the VGPS website, and the CGPS page of the Canadian Astronomy Data Centre [CADC]). The VGPS is a component of the International Galactic Plane Survey (see the IGPS website).
