Two 2°x2° fields centred at l=30° and l=59° have been observed with the SPIRE and PACS photometric cameras in parallel mode during the Herschel science demonstration phase (SDP). From the images, compact sources are extracted for which the distance must be established in order to determine their physical properties. The aim of this paper is to present the distance determination strategy for the Hi-GAL compact sources. We illustrate this strategy for the two fields at l=30° and l=59°. Description: We obtain velocities along the line of sight to Hi-GAL sources, where possible, using CO data observed with the SEQUOIA receiver on the FCRAO 14m telescope. In the l=30 ° region we use the 13CO J=1-0 data from the BU-FCRAO Galactic Ring Survey (GRS, Jackson et al., 2006ApJS..163..145J) while in the l=59° region we use 13CO and C18O J=1-0 observations obtained as part of the Exeter-FCRAO CO Galactic Plane Survey (Brunt et al., in prep.).

Note (1): if not indicated, the stellar distance (Dist) is adopted Note (2): "Wat", "SW", "A" correspond to radio sources listed mainly in Watson et al. (2003ApJ...587..714W), Sewilo (2004, Cat. J/ApJS/154/553) and Anderson et al. (2009, Cat. J/ApJS/181/255), respectively. The molecular information is from Dame et al. (1986ApJ...305..892D) for "GMC", from Roman-Duval et al. (2009ApJ...699.1153R) for "GRSMC" clouds, from Solomon et al. (1987ApJ...319..730S) for "Sol" clouds, from Jacq et al. (1988A&A...195...93J) for "Bx" clouds and from Simon et al. (2006, Cat. J/ApJ/653/1325) and Jackson et al. (2008, Cat. J/ApJ/680/349) for "IRDC". For "GMC" and "Bx" clouds the radius and velocity FWHM of the cloud is given in brackets. Note that the typical radius and velocity FWHM of "GRSMC" clouds are 0.35±0.12 degrees and 3.57±1.21km/s. These values are lower than the typical values for GMC. Note (3): When different values are found in the literature, they are given separated by a semicolon. If several velocities (along the line of sight) are measured they are separated by a backslash. Note (4): Near/far/tangent solution mainly from HI emission/absorption or HI self-absorption methods and references. N means near, F means far, T means tangent. When two solutions are proposed in brackets the first comes from the HI emission/absorption method, the second from the HI self-absorption method (Anderson & Bania, 2009, Cat. J/ApJ/690/706). For sources where the two methods disagree, the favoured one by Anderson & Bania (2009, Cat. J/ApJ/690/706) is marked with an asterisk. Note (5): References as follows: a = Watson et al. (2003ApJ...587..714W) b = Solomon et al. (1987ApJ...319..730S) c = Sewilo et al. (2004, Cat. J/ApJS/154/553) d = Pandian et al. (2008, Cat. J/A+A/486/191) e = Kolpack et al. (2003, cat.
