METHOD AND APPARATUS FOR VISUALLY COMPARING GEO-SPATIALLY ALIGNED DIGITAL CONTENT ACCORDING TO TIME

Abstract:

In example embodiments, techniques are provided for visually comparing digital content for an infrastructure project according to time using 4-D construction modeling software. The 4-D construction modeling software includes a cloud-based 4-D comparison service and a local 4-D modeling client. The 4-D comparison service includes a digital content alignment service and a 4-D difference engine. The digital content alignment service aligns different pieces of digital content and produces views that provide visual comparison between different pieces of digital content. The 4-D difference engine automatically determines differences between different pieces of digital content. The 4-D modeling client includes a 4-D comparison user interface (UI) process that receives user input used to generate, and then displays a generated visual comparison between different pieces of digital content. The 4-D comparison UI utilizes time control channels for selecting digital content and comparison controls for selecting a type of visual comparison.
