NOTAM are essentially circles of influence around a well-defined point. In some cases we are able to more specifically narrow down the displayed area, but only in special well-defined circumstances as they were never designed to convey geospatial information. We can generally display polygons and lines if the coordinates are well formatted.
SkyDemon is used by militaries throughout Europe and NOTAM do not have a flag saying "military interest only" so we are unable to give the user an option to filter out such NOTAM.
