It’s Unstoppable and Headed Your Way

This entry is part 7 of 7 in the series PangaeaFrom time to time I like to stop and think about the mission of Pangaea and explain that mission to you. My task is exposing you to new, emerging geospatial technologies. But why bother? Here’s a little analogy I thought of to help explain why...

High-definition mapping sensors (lidar, digital, and oblique imagery, here mounted on a helicopter during collection of an autonomous vehicle mapping project) provide an accurate, cost-effective approach to limit the interference and potential delays related to collecting extensive control on a right of way.
