10 Year Anniversary!

10 years ago today I formed Aaslestad Preservation Consulting llc to better pursue my interest in ways of capturing, understanding, and visualizing the built world. Its led me to some great collaborations in unique places. I’m very grateful and looking forward to new horizons under changing skies, somehow still afloat and seaworthy!

View of “internal organs”

Using a medical analogy to understand new ways of accessing point cloud data… The slide above shows the point cloud in RECAP software with the exterior envelope layer turned off, revealing the cluster of internal spaces.

The slides below show a series of “slices” taken vertically through the buildings at 1 meter intervals, from north towards the south and then from east proceeding towards the west.
