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： Ø main carrying body of information resource in sustainable development, Ø effective way to integrally share the information resource, Ø strategic highland in information era Øan 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 “。 Space-borne Remote sensing Air-borne Remote Sensing GPS Digitizing instrument Engineering scanner Total station RS image receiving and processing Graph data processing and editing DEPS platform Spatial information database server (DEPS center database) Grid computing Model database server Meta database server Virtual Reality center Metadata service Map application service Resource data sharing Application server Model database server Data Receiving and Fast Processing Subsystem …… Internet 3D Simulation application Analysis model service 二、系统组成与功能 Space-borne Remote sensing Air-borne Remote Sensing GPS Digitizing instrument Engineering scanner Total station RS image receiving and processing Graph data processing and editing DEPS platform Spatial information database server (DEPS center database) Grid computing Model database server Meta database server Virtual Reality center Metadata service Map application service Resource data sharing Application server Model database server …… Internet 3D Simulation application Analysis model service 二、系统组成与功能 Model Base Subsystem Space-borne Remote sensing Air-borne Remote Sensing GPS Digitizing instrument Engineering scanner Total station RS image receiving and processing Graph data processing and editing DEPS platform Spatial information database server (DEPS center database) Grid computing Model database server Meta database server Virtual Reality center Metadata service Map application service Resource data sharing Application server Model database server …… Internet 3D Simulation application Analysis model service 二、系统组成与功能 Meta-data Service Subsystem Space-borne Remote sensing Air-borne Remote Sensing GPS Digitizing instrument Engineering scanner Total station RS image receiving and processing Graph data processing and editing DEPS platform Spatial information database server (DEPS center database) Grid computing Model database server Meta database server Virtual Reality center Metadata service Map application service Resource data sharing Application server Model database server …… Internet 3D Simulation application Analysis model service 二、系统组成与功能 Grid Computing Subsystem Space-borne Remote sensing Air-borne Remote Sensing GPS Digitizing instrument Engineering scanner Total station RS image receiving and processing Graph data processing and editing DEPS platform Spatial information database server (DEPS center database) Grid computing Model database server Meta database server Virtual Reality center Metadata service Map application service Resource data sharing Application server Model database server …… Internet 3D Simulation application Analysis model service 二、系统组成与功能 Spatial Information Database Subsystem Space-borne Remote sensing Air-borne Remote Sensing GPS Digitizing instrument Engineering scanner Total station RS image receiving and processing Graph data processing and editing DEPS platform Spatial information database server (DEPS center database) Grid computing Model database server Meta database server Virtual Reality center Metadata service Map application service Resource data sharing Application server Model database server …… Internet 3D Simulation application Analysis model service 二、系统组成与功能 Map Service Subsystem Space-borne Remote sensing Air-borne Remote Sensing GPS Digitizing instrument Engineering scanner Total station RS image receiving and processing Graph data processing and editing DEPS platform Spatial information database server (DEPS center database) Grid computing Model database server Meta database server Virtual Reality center Metadata service Map application service Resource data sharing Application server Model database server …… Internet 3D Simulation application Analysis model service 二、系统组成与功能 Virtual Reality Subsystem •Digital touring •Digital archaeology •Digital Olympics •Dynamic Urban Change Monitoring •National Standard Digitalization Base Applications in different areas VR_TOUR6 Digital Touring •Digitized and network management of Huangguoshu view designation sector •development of the 3D simulation system and Internet browsing software •establishment of the GIS information inquiring links DSC04777 111 未标题-3 VR_TOUR5 Digital Archaeology case_4_1 qbmas IKONOS images of Zhenbeitai, Yulin, Shanxi and its surrounding environment analysis Remote sensing survey of Hailongtun Remote sensing survey of Tongwancheng Digitized photo database of World War II Digital Olympics • •Implementation of the dynamically monitoring of the Olympic main venue sector projects and the environment projects in spatial scale;

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.
