ANNOUNCEMENTS
Esri, the global leader in location intelligence, recognized
Dewberry
with a Partner Conference Award for Maximizing
ArcGIS in Service Offerings at this year’s Partner Conference.
The firm was selected based on its work with Esri to integrate
elevation and hydrography tools in its new ArcGIS Pro software.
For more than 30 years, Dewberry has been an industry leader
in geospatial and remote sensing technologies, and recently
published the third edition of the DEM Users Manual, which
serves as a guide to 3D elevation technologies, products, and
applications.
“Ourlong-standingpartnershipwithEsrihasbeeninstrumental
in the success of our geospatial practice at Dewberry,” says
Dewberry Associate Sid Pandey, CSM. “As geospatial technology
continues to evolve at a rapid rate, we’re eager to help the
communities where we live and work be successful and resilient
by using the data and technology that we’re developing with the
help of organizations like Esri.”
“Having spent more than 30 years in this industry, I am
thrilled to see the advances that technology is making, and we’re
proud to be at the forefront of those changes,” states Dewberry
Executive Vice President Phil Thiel.

Spectral Evolution’s
PSR+ spectroradiometer was used in an
advanced environmental science class at Colorado College in
Colorado Springs during January/February 2019. This intensive
3.5-week undergraduate course called “Climate Change in the
High Alpine” with Dr. Ulyana Horodyskyj as the instructor,
integrated science and technology, providing students the
opportunity to get their hands dirty through field experiences
in the high alpine regions in Colorado. It was composed of 27
students, mostly junior and senior undergraduates.
“Class assignments included completing a series of “alpine
challenges” and writing up the results in technical reports,” said
Dr. Horodyskyj. “As an example, for one challenge students were
members of a US Geological Survey team, tasked with solving
a scientific problem while provided with a small budget,” she
added. Students were taught how to build their “field toolboxes”
and how to effectively use tools such as Google Earth, Excel and
SNICAR (a numerical modeling program that shows the impacts
of pollution on snow), backcountry snow kits, handheld Kestrels
(weather stations), aerial and underwater drones, and a full-
resolution visible/near-infrared spectroradiometer sponsored by
Spectral Evolution. “The course provided multiple opportunities
for hands-on experience using scientific instrumentation to
answer specific questions, depending on the alpine regionwe were
studying,” Dr. Horodyskyj said. “In many cases, the students did
not have prior experience with the instrumentation, including
the spectroradiometer, and they commented on the ease of use,
especially in challenging field conditions.”
In order to determine how pollutants such as black carbon and
natural contaminants (like dust) impacted the snowpack, the
PSR+ was useful in providing snow “spectral fingerprints.” The
dirtier the snow, the less the reflectance, which is clearly visible in
the spectrum. The less reflectance, the more the snow can absorb
solar radiation and melt faster. Spectral changes, given amounts
of snow contaminants, can be numerically modeled using the
online SNICAR tool mentioned above and compared with actual
field data collected from the PSR+. In order to determine whether
such drops in reflectance were due simply to natural causes (such
as snow grain size differences), students also collected field data
with backcountry snow kits. “Given its high resolution, ease
of use, and clean data (we collected data with a lens and not a
contact probe), the PSR+ was incredibly useful in the field for
snow/ice applications,” Horodyskyj said.

GeoCue Group
announced today the release of Get3Di, a
geospatial data portal specifically designed to make finding,
accessing, and downloading our nation’s vast collection of
public Lidar and Image data sources (3Di) as easy as any online
shopping experience.
Get3Di differs from other online geospatial data portals by
offering public data that can be used for any purpose, royalty free.
Subscription prices are set to recover data download costs.
Hank DiPietro, GeoCue’s VP of Business Development, says,
“Our mission with Get3Di is to make public 3D data easy to find
and download. Currently, to get quality public data you must
look through multiple sites or try to download the data from a
crowded server. We designed Get3Di to solve that problem. Our
goal is to make Get3Di the ‘one-stop-shop’ of the best public 3D
imagery data in the United States.”
Get3Di can be accessed at get3di.com .
The initial release of Get3Di focuses on the state of Florida,
other state datasets are coming online daily. If you are a public
data provider and want more information on how your state can
participate in Get3Di, please contact
