Spatial computing and spatial big data have already enriched billions of lives via pervasive services
(e.g., navigation and ride-sharing apps), ubiquitous systems (e.g., geographical information system,
spatial database management system), and pioneering scientific methods (e.g., spatial statistics).
2 billion receivers in use for location and time services, the GPS has become a critical
infrastructure for the world economy for use cases ranging from
to navigation to ride sharing to
smart cities. Moreover, billions of weather forecasts are used every day around the
global agriculture is monitored to anticipate and prevent food shortage
leveraging spatial big data from Earth Observation satellites.
These success stories are only a beginning and many transformative opportunities lie ahead.
a 2019 U.S. national academy report projects $1.6 trillion in savings for energy generation
and use from earth observation data by 2035. Earlier,
the 2011 Mckinsey Big Data report
estimated that location trace data will generate about $600 billion annually by 2020.
Furthermore, government and industry have recently started major initiatives such as
NASA Earth Exchange, Amazon Earth on AWS,
Google Earth Engine,
Microsoft AI for Earth, and NSF
Navigating the New Arctic
for meeting grand challenges facing our changing planet such as climate change
and environmental sustainability.
However, many spatial data science questions need to be probed to realize the transformative potential.
For example, how may modern economy survive wide-spread GPS-jamming (or spoofing)?
How may one continuously monitor our changing planet at high spatial resolution even during nights?
How may spatial big data (e.g., smart-phone trajectories) be mined without violating privacy ?
How may machine learning methods be generalized to address spatial challenges
(e.g., auto-correlation, multi-scale, modifiable areal unit problem such as Gerrymandering)?
How may we address spatial bias in data even when social feedback loops increase it?
How may algorithms scale up to spatial big data to learn unbiased models?
How may we leverage vehicle big data (e.g., on-board diagnostics with high
spatio-temporal resolution) for eco-routing to model edge dependence of energy-use and emissions?
This presentation shares a perspective on the societal accomplishments,
opportunities, and research needs in spatial computing, spatial big data and spatial data science.
