Our GIS and data experts
are always stirring up conversation so we decided to
let them go global with a blog.
Join the conversation with Fred Zimmerman,
host of Global
Data Hound, and his occasional guest bloggers.
GLOBAL DATA HOUND - A CONVERSATION ON DATA
As a Research Scientist our data hound, Fred Zimmerman,
spends much of his time sniffing out data. Fred makes
of the collective skill set here at ISciences. We
years of experience
in identifying, acquiring, and creating global datasets to
illuminate complex scientific, socio-economic, and
policy problems. Find out what the Global
Data Hound has sniffed out today. You'll find a discussion
of pixel sizes and map scales for global gridded datasets and
some thought-provoking images like the HANPP data
The Global Data Hound also draws on guest bloggers to help frame and parse important geospatial issues.
Dave Carson, Director
of GeoSpatial Solutions at ISciences, is the ultimate tour guide to digital spatial data exploitation - from dataset selection and integration, to visualization, to analysis.
Thomas Parris, VP and Director of Sustainability Programs at ISciences, and a frequent contributor to Environment magazine, brings his inciteful analysis to the GIS challenges and opportunities presented by global sustainability issues.
Map: Human Appropriation of Net Primary
Image Source: CIESIN
Remarks from the Global Data Hound: "HANPP
shows human appropriation of net primary productivity
as a percentage of local
primary productivity, so you can think of it as a
measure of the stress that humans are putting
on the local
ecological resources (or, if you will, as a measure
of the efficiency with which humans have turned the
local ecology to our purposes). The point is not
that the HANPP map is exactly 'right' as
a literal representation of reality, but
rather that it is directionally illuminating
and thought-provoking. That’s often
the case for any global map that does more
than count known entities. Cartography has
a strong element of art."
