"They don’t have ground penetrating memory," No, they don't. I'll point out that the article mentions they "remove the dense tree canopy to create a 3D map".

"They don’t have ground penetrating memory," No, they don't. I'll point out that the article mentions they "remove the dense tree canopy to create a 3D map". It does not say "they used ground penetrating Lidar". Seems to me you underestimate what they know and overestimate what you know and that is exactly what I was saying they found irksome.
