Come and join Sen Xu for a tech talk based on his past 6 years of industry experience, all in the field of Geo applications. The topics covered in this talk includes:

  1. What's the de facto standard of Spatial Indexing technique that Google/Twitter/Uber uses in production?
  2. How do software patents work in the industry?
  3. What are the common challenges industry face when working in the field of geo/mapping tech?
  4. Exploratory application on the new frontier of mapping.

Sen Xu is a PHD candidate (ABD) from Penn State Univ's Geography department. His advisor is Prof. Alexander Klippel.
