The H.E.S.S. Galactic Plane Survey (HGPS), the first comprehensive survey of\nthe inner Galaxy at TeV energies, has led to the discovery of an unexpectedly\nlarge and diverse population of over 60 sources of TeV gamma rays within its\ncurrent range of l = 250 to 65 degrees in longitude and |b| < 3.5 degrees in\nlatitude. The data set of the HGPS comprises 2800 hours of high-quality data,\ntaken in the years 2004 to 2013. The sensitivity for the detection of\npoint-like sources is at the level of 2% Crab or better in the HGPS region. The\npopulation of TeV gamma-ray emitters is dominated by the pulsar wind nebula and\nsupernova remnant source classes, although nearly a third of the sources remain\nunidentified or ambiguous. We are presenting the latest HGPS significance and\nsensitivity maps, as well as a work on the HGPS source catalog, based on a\nuniform re-analysis of the full data set collected in the last decade. We will\nalso give a brief overview of the H.E.S.S. Galactic source population.\n
