Location: 

CGIS Knafel, room K262 (Bowie-Vernon room) or Virtual via Zoom

Speaker

Daniel Krol, Sandstorm Community Project

Abstract

In the modern era of data collection by governments and corporations, concerns have grown over user privacy and autonomy in personal and cloud computing. One outgrowth of this concern is the "self-hosting" movement which promotes open source web applications that are made for users to install and manage themselves, ideally on their own hardware. Self-hosting is an alternative to using... Read more about Desert Atlas: Building A Self-Hosted, Collaborative, Online Map that is Easy and Private (GIS Colloquium)

Semi-Arid Carbon Stocks of 9.9 Billion Trees from 326,000 Commercial Satellite Images

12:00pm to 1:00pm

Location: 

CGIS South, room S050 (Thomas Chan-Soo Kang Room) and virtual via Zoom

Presenter

Dr. Compton J. Tucker

Abstract

Dr. Compton Tucker will describe the marriage of commercial satellite data, machine learning with high performance computing, and field measurements, which together enabled the carbon content of ten billion semi-arid trees to be estimated with an uncertainty of ±20% over an area of 10 million km2. Dr Tucker found that his team's results differ from all previous studies using observations, and from numerical simulation models. The voluminous output data required the...
