Business Wire
DigitalGlobe, Inc. (NYSE: DGI), the global leader in Earth
imagery and information about our changing planet, today announced
the SpaceNet Challenge Round 2 results and plans for the next two
SpaceNet Challenges. A collaboration between DigitalGlobe, CosmiQ
Works, and NVIDIA, SpaceNet leverages an online repository of
publicly accessible satellite imagery, co-registered data layers
for training algorithms, and prize challenges to accelerate
innovation in machine learning.
The SpaceNet Challenge Round 2, hosted on TopCoder, was a
continuation of the first competition and invited participants to
improve automated mapping algorithms for building footprint feature
extraction from overhead imagery. Building on the success of the
first competition, SpaceNet Round 2 incorporated several
enhancements, including the release of higher resolution imagery
from WorldView-3 (30 cm resolution), improved building footprint
training data from four new geographically diverse areas and an
extended competition length to provide more time for algorithm
development.
The winning algorithms achieved performance with potential for
automated mapping tasks. Such algorithms can help keep maps
up-to-date at scale and serve end-users when current information is
needed to direct resources, such as first responders during natural
disasters. CosmiQ Works’ blog post provides further technical
detail on the top three winning solutions. As in the first
challenge, the winning algorithms are available to the open source
community through the SpaceNet GitHub repository and users of
DigitalGlobe’s Geospatial Big Data platform, GBDX.
“SpaceNet’s innovation is having a meaningful impact within the
first year, thanks to the collaboration between developers and data
scientists to apply open data and machine learning in the
geospatial field,” said Tony Frazier, Senior Vice President and
General Manager of DigitalGlobe | Radiant. “The results from Round
2 show developers are harnessing machine learning and
high-resolution training data to achieve outcomes that indicate
automation could be used in the near future to support broader
geospatial analytics. We are excited to grow the SpaceNet training
datasets library for an even broader range of applications and
hosting additional public competitions to further machine learning
capabilities in the future.”
The third SpaceNet Challenge will shift focus from automated
building footprint extraction to road network extraction and
optimized vehicle routing. This challenge will utilize machine
learning to gain insights into transportation networks and
navigation. The fourth competition will focus on processing
off-nadir imagery produced by high-revisit constellations, like
DigitalGlobe’s next-generation WorldView Legion constellation, in
unprecedented rapid timelines and at global scale. The goal of this
challenge will be to create algorithms that automatically detect
objects from more diverse angles than current nadir imagery. More
information on these upcoming challenges will be available as they
approach starting in fall 2017.

to any of our satellites; delays in the construction and launch of
any of our satellites or our ability to achieve and maintain full
operational capacity of all our satellites; loss or damage to the
content contained in our ImageLibrary; interruption or failure of
our ground systems and other infrastructure; decrease in demand for
our imagery products and services; increased competition that may
reduce our market share or cause us to lower our prices; changes in
political or economic conditions, including fluctuations in the
value of foreign currencies, interest rates, energy and commodity
prices, trade laws and the effects of governmental initiatives to
manage economic conditions; our ability to recruit, hire or retain
key employees or a highly skilled and diverse workforce; failure to
obtain or maintain required regulatory approvals and licenses; and,
changes in U.S. or foreign law or regulation that may limit our
ability to distribute our imagery products and services. Additional
risks and uncertainties related to the proposed transaction with
MacDonald, Dettwiler and Associates Ltd. (“MDA”) include the
possibility that the parties may be unable to obtain required
regulatory approvals or that other conditions to closing the
transaction may not be satisfied, such that the transaction will
not close or that the closing may be delayed; the potential adverse
effect on partner and customer relationships, operating results and
