The document discusses how 2 billion jobs may disappear as technology disrupts various industries. Jan Grønbech, the Country Director of Google Norway, emphasizes that companies must either disrupt their industries or be disrupted by other innovative competitors. He notes that while such disruption can eliminate many jobs, it can also create new types of jobs to drive industries forward in a changing environment.
This document discusses the power of imagery in GIS platforms and ArcGIS specifically. It highlights that imagery is at the heart of many GIS systems and the ArcGIS platform is highly capable for imagery. ArcGIS allows users to see imagery, find patterns within imagery remotely, and share imagery and insights with others. New products like Drone2Map for ArcGIS help turn drone imagery into enterprise tools for tasks like orthomosaicking, 3D modeling, and inspections.
