The question from Vacre was: Is it possible the lower altitude is due to inferior technology?
Moores Law is somewhat relevant for sensors and data throughput, but there are other factors, like the desired scale and application that dictate flying height. Some applications demand low & slow.
For comparison: WorldView-3 at 400+km altitude, can't be construed to mean the aircraft capture systems used by Airborne operators like Nearmap must therefore be inferior. The different altitudes, indicate a different product to cater for a different scale.
It's the same reason photographic studios don't do portrait photography using 800mm lenses, or shoot sports events using a mobile phone with a 0.8μm CMOS. The seasoned photographer will select the right combination of tools for the job.
