DESCRIPTION
“A Case Study in organization wide access to advanced analytical tools for broadband design” Technology is moving quickly to allow new methods and improved access to analyses that used to be only accessible by a few people with specialty software, hardware and skills sets. This presentation will show a case study on how advanced 3D analysis of view-shed, least cost path analysis and elevation data is able to be brought to anyone in your organization or your clients using Esri, Microsoft and Cloud technologies. This presentation will step through the solution as it was implemented for various organizations, then delve into the technology that makes this analysis a reality. Finally, we will review current 3D and web technologies and how they might help you and your organization.

Conclusion
Why Does this Matter to you?
Accessibility – Who needs the result? Usability – If elevation matters you should
see it. Affordability – APIs that were accessible
and free
Complex made Simple
