Abstract: Imaging the solar polar regions remains a challenging endeavor - a victim of solar system geometry and orbital mechanics. There are dedicated spacecraft with ecliptic advantages to more directly image these regions, however, they do not always provide dedicated long-term data sets. Towards this aim, we have developed a technique for reconstruction of polar imagery using existing EUV datasets, with a focus on coronal hole features. Using this methodology, we create virtual EUV imagers sitting stationary above the North and South solar poles, with the dataset spanning the observational range of SDO / AIA data. These data are outlined, along with the use of these data to better constrain the extent of polar coronal holes and enclosed magnetic flux over the span of solar cycles 24 and 25.
