#25 Evaluating SpaceNet 5 Challenge Results: Road Network Detection & Optimized Routing
Despite its application to myriad humanitarian and civil use cases, automated road network extraction from overhead satellite imagery remains quite challenging. However, the SpaceNet 5 challenge made significant progress in this field with top participants being able to extract both road networks and speed/travel time estimates for each roadway. On today’s pod, CosmiQ’s Ryan Lewis and Dr. Adam Van Etten explore the challenge’s unique dataset and geographic diversity over time, the winning models, and the tradeoff between inference speed and model performance.
SpaceNet is a nonprofit LLC co-founded and managed by In-Q-Tel CosmiQ Works in collaboration Maxar Technologies, a co-founder, and the other SpaceNet Partners: AWS, Intel AI, Topcoder, Capella Space, IEEE GRSS, The National Geospatial-Intelligence Agency (NGA), and Planet.

#24 Viewing the World Through a Straw
How can lessons from geospatial computer vision applications impact bio image analysis? CosmiQ’s Dr. Nick Weir and B.Next’s Dr. Dylan George explore the intersection of these two fields and why artificial intelligence (AI) has struggled to gain traction with both satellite imagery and medicine. Hear about their project that researched similarities and differences between satellite imagery, microscopy, and “normal” photographs, and why researchers developing AI methods for microscopy might want to leverage the work done for geospatial applications.

#23 Into the Gray Zone: Emerging Technology’s Role in the Geopolitical Landscape
How does emerging technology like artificial intelligence (AI) fit into the broader geopolitical landscape, particularly one that continues to rapidly evolve? CSIS’s Melissa Dalton and Lindsey Sheppard join the podcast to discuss their recent research project, the Gray Zone Project, on current challenges faced by the U.S. and its allies, and how emerging technologies could be leveraged to help resolve or mitigate some of the analytic tasks facing national security organizations.
CSIS is an independent, bipartisan think tank in Washington, D.C. focused on producing objective analytic analysis that is targeted primarily toward U.S policy makers, but also an increasingly broader audience to include the tech community, allies and partners, and private sector. CSIS’s International Security Program analyzes how the U.S. can best deter, campaign in, and respond to “gray zone” approaches.

#22 Machine Learning Robustness Study: Building Out an Increasingly Diverse Dataset
How much labeled data does a machine learning model need in order to achieve sufficient performance? Most analyses simply use all available data and focus on model architecture, with scant attention given to whether the dataset size is appropriate for the task and architecture’s complexity. But is that the right answer?
In this episode, IQT CosmiQ Works’ Ryan Lewis, Daniel Hogan, and Adam Van Etten dive into the importance of deep quantitative analysis and the impact of training data size on model performances. Learn how they used CosmiQ’s Machine Learning Robustness Study to help address dependence on geography and dataset size at the leading edge of geospatial machine learning.

#9 Analyzing Times Series Data for Humanitarian Response
Dylan George from In-Q-Tel’s (IQT) B.Next joins CosmiQ Works’ Jake Shermeyer and Ryan Lewis to discuss how a time series of satellite imagery can be used in humanitarian response scenarios. A time series of satellite images can play a major role in these scenarios and assist practitioners in identifying areas that experience a change in population, the loss of electrical power, and/or rapid changes in land-cover. The podcast addresses two main questions: (1) How can practitioners quickly analyze these time series with open source software tools, such as CosmiQ’s CometTS tool suite; and (2) How can those tools be used to support a humanitarian response effort?
Learn how CosmiQ tackled these questions with their CometTS tool suite through the study of satellite imagery of Puerto Rico following Hurricane Maria. (31 min)

#8 Introducing Solaris: CosmiQ’s Open Source Python Library for AI
Performing machine learning and analyzing geospatial data are both hard problems requiring a lot of domain expertise. These limitations have historically meant that one needs to be an expert in both to perform even the most basic analyses, making advances in AI for overhead imagery difficult to achieve. Is there anything we can do to reduce this barrier to entry, making it easier to apply machine learning methods to overhead imagery data?
Ryan Lewis and Nick Weir tackle that question as they discuss one of CosmiQ’s new project, Solaris, a new open source Python library for performing and evaluating machine learning analyses of overhead imagery. Solaris provides an easy-to-use, end-to-end analysis pipeline for AI model training, prediction, and performance assessment, along with providing pre-trained winning models from the SpaceNet® Challenges for comparison.

#7 Are We There Yet? Announcing SpaceNet 5: Roads, Routes, & Travel Times
Determining optimal routing paths in near real-time is at the heart of many humanitarian, civil, military, and commercial challenges. This statement is as true today as it was two years ago when the SpaceNet® partners announced the SpaceNet Challenge 3, focusing on road network detection.
On today’s pod we are joined by Ryan Lewis and Adam Van Etten to learn about SpaceNet’s upcoming fifth challenge that revisits road detection, routing, and now travel time estimation from satellite imagery. This public challenge will test participants’ ability to automatically extract road networks from satellite imagery, along with travel time estimates along all roadways, thereby permitting true optimal routing.
SpaceNet is a collaborative effort between CosmiQ Works, AWS, Maxar, and Intel AI. Learn more at www.spacenet.ai. (25 min)

#6 Enabling Analytics (+ Security) at the Edge
Consider all of the onboard analytics necessary for autonomous/semi-autonomous car operations such as lane assist. These offerings present a new attack surface for malicious actors in a myriad of industries ranging from automotive to space systems. Yet, market trends are clearly moving towards more increasing connectivity and expanding edge analytics for most of the devices we use in our daily lives. The question becomes the following: what can organizations do to increase cybersecurity of their embedded systems while these market dynamics unfold?
Join us for a discussion with Red Balloon Security’s Founder and CEO, Dr. Ang Cui, and Research Scientist Joseph Pantoga, to learn about security implications (and potential solutions) of deploying artificial intelligence models to connected embedded devices.
