The field of Very-High-Energy (VHE, E>100 GeV) gamma-ray astronomy is entering an era of precision measurements. Over the last decade, innovations in instrumentation have led to a drastically improved understanding of the most energetic objects in the Universe. New results by the High Altitude Water Cherenkov Observatory (HAWC) have shown the unique insights that large-field-of-view survey instruments like HAWC can provide to the field. The recent 2HWC catalog and other publications have revealed gamma-ray emission from several large extended sources such as TeV halos surrounding pulsar-wind nebulae. Synergies between ground- and space-based survey and pointing instruments have already led to the identification of several new sources and source candidates. In this poster, we will explore the potential of future improvements to the field. In particular, the proposed Southern Gamma Survey Observatory (SGSO) will further improve our view of the VHE sky. We will discuss future opportunities for Galactic astrophysics: Further study of TeV halos, the search for large extended structures such as possible counterparts of the Fermi bubbles at TeV energies and gamma-ray emission from molecular clouds. The SGSO, with its wide field of view and low energy threshold compared to current ground arrays, is particularly suited to the study of these objects, which may extend beyond the field of view of most IACTs.
