I find stereo pair aerial imagery hugely helpful in understanding terrain. While Google Earth is great to get a gross overview, our eyes are much better at inferring sub-meter detail from pairs of stereo photos, e.g. from a single airplane taken a few seconds apart. What are some good sources of public aerial stereo imagery? The only source I've found is NOAA https://www.noaa.gov/topic-tags/aerial-imagery https://www.noaa.gov/topic-tags/aerial-imagery
