Digital Earth is a concept that aims to
incorporate maps and data – ranging from
topography and population to weather
patterns and migration – into a seamless
geospatial system accessible
worldwide.

Understanding Digital Earth
(White paper by NASA Digital Earth office, 2000)
The Digital Earth: Understanding our
planet in the 21st Century by Al Gore
• Nová vlna technologických inovací nám dovoluje sběr,
ukládání, zpracování a zobrazování nepředstavitelného
množství informací o naší planetě a široké rozmanitosti
přírodních a kulturních jevů. Většina těchto informací je
“georeferenčních”, to znamená, že jsou vztažena k
určitému specifickému místu na zemském povrchu.
• Obtížnou součástí využití těchto předností je záplava
geoprostorových informací – problémem je převedení
surových dat do pochopitelných informací.
• Digital Earth: vícenásobná zobrazení, třídimenzionální
reprezentace planety, při němž využíváme velké
množství georeferenčních dat.
Digital Earth - nezbytné technologie
• Počítačové vědy resp. Informatika (Computer
Science)
• Obrovské ukládací kapacity pro data (Mass Storage)
• Družicové snímky (Satellite Imagery)
• Širokopásmové sítě (Broadband Networks)
• Interoperabilita (Interoperability)
• Metadata -Realizovat úplný potenciál Digitální Země
vyžaduje technologický pokrok v dalších oblastech,
zejména automatizované interpretaci snímků,
propojování dat z rozmanitých zdrojů, a inteligentní
agenty, kteří mohou nalézti a propojit informaci na
WEBu o jakémkoliv místě na zeměkouli. Už
v současnosti je k dispozici dostatečné množství
informací, aby proces mohl být úspěšně rozvíjen.
Digital Earth - potenciální aplikace
• Vedení virtuální diplomacie (mírové rozhovory
v Bosně, simulovaný let nad plánovanou hranicí,
stanovaní koridoru)
• Boj s kriminalitou (pomocí GIS v městě Salinas)
• Ochrana zachování biodiversity: (Camp Pendelton,
California, předpověď růstu populace z 1.1 milion v r.
1990 na 1.6 milion v r. 2010. V regionu 200
ohrožených, vzácných rostlin a živočichů. Na
základě informací o terénu, půdních poměrech,
ročních srážkách, vegetaci, využití půdy a
vlastnických vztahů vědci modelovali možné dopady
na biodiversitu v regionu
Předpovědi klimatických změn: (odlesňování
Amazonských pralesů na základě družicových
dat)
Růst zemědělské produktivity: (družicové
snímky a GPS pro včasnou detekci nemocí a
škůdců a nasazení protiopatření; “farming by
the inch."
Background
• Digital Earth：
 main carrying body of information resource in sustainable
development,
effective way to integrally share the information resource,
strategic highland in information era
an essential character in economy and society.
• In the late 90’s, Digital Earth concept was widely
disseminated and quickly developed. Both China
and foreign countries had experienced a completely
process in the understanding of Digital Earth
• Brought out the Digital Earth Prototype System
(DEPS) proposal

The initiative envisions a three-dimensional
globe that users could click on to access
data layers.
Sufficient data depth and breadth would
ensure its use by researchers, local,
planners, and students.
The project encompasses standards
development, idea marketing, and data
collection and draws openly on the work of
other organizations.
Like GSDI, the Digital Earth initiative
(http://www.digitalearth.gov) has contributed
to advancing the concepts and technologies
that underlie any SDI and by structuring
existing information relevant for the
implementation of interoperable geographic
information and services.
As a matter of fact, the Digital Earth
initiative has made important contributions
to the GSDI Cookbook.
