We attemp to make a complete census of massive-star formation within all of GMC G345.5+1.0. This cloud is located one degree above the Galactic plane and at 1.8kpc from the Sun, thus there is little superposition of dust along the line-of-sight, minimizing confusion effects in identifying individual clumps. GMC G345.5+1.0 is located approximately between 344.5° and 346.5° in Galactic longitude, and between 0.2° and 2.0° in Galactic latitude. Description: Observations toward the whole GMC 345.5+1.0 were made using SIMBA Bolometer in 1.2mm continuum emission. The observations have a spatial distribution of 0.2pc and cover 1.8°x2.2° in the sky with a noise of 20mJy/beam. 201 clumps were identified with diameters between 0.2 and 0.6pc, masses between 3.0 and 1.3x103M, and densities between 5x103 and 4x105cm-3. Observations were made in October 2002 and July 2003. File Summary:
