Elements
of the Internet Computing Model for Geoprocessing
The Internet
Computing Model for Geoprocessing consists of the core
technologies and standards for implementing distributed geoprocessing,
which are woven into mainstream IT as an integral part of the global
information economy.
The
key elements of the model are defined below:
- Digital
Earth A virtual model of the earth, comprised of
the total set of geospatial holdings on the Net. These holdings
are bound together as a coherent, consistent and universal
earth model by virtue of common standards for geospatial data
and geoprocessing. The Digital Earth is part of the Global
Information Infrastructure.
- Geospatial
Components The plug-and-play building blocks for
ubiquitous geoprocessing. Multipurpose components with standardized,
easily composed interfaces and well-defined behaviors.
- Geospatial
Agents Active (mobile on the Net), autonomous applications
that have the means to search, discover, access, interact and
assimilate geo-intelligence from remote services (e.g. geospatial
servers and appliances). They are comprised of one or more
geospatial components.
- Net-enabled
Geospatial Applications Standalone geospatial applications
that access other Net-based resources, including net-source
geospatial servers, data, applets, agents and appliances. They
are comprised of one or more geospatial components.
- Net-source
Geospatial Servers Net-enabled servers that are
capable of serving subsets of their geospatial data and/or
geospatial applet holdings to remote clients that are requesting
service. The clients may be geospatial applications, applets,
appliances or other geospatial servers. They are comprised
of one or more geospatial components.
- Net-source
Geospatial Data Geospatial data that are packaged
and transported over the Net.
- Net-source
Geospatial Applets Plug-in geoprocessing applications
that can operate through a Web browser. Comprised of one or
more geospatial components. Geospatial applets can be easily
transported over the Net.
- Net-source
Geospatial Appliances Spatially-enabled devices
that are accessible on the Net. They are comprised of one or
more geospatial components.
- Geospatial-hybrids Any
applications, servers, data, applets, agents and appliances that
make use of geospatial data and embedded geospatial components,
but serve primarily a non-geospatial oriented purpose.
- The
Net The Global Network Infrastructure that supports
distributed communications and computing, including the physical
network, network computers and core network services. This
infrastructure includes Java Platform and Jini; the core software
technologies for enabling distributed geoprocessing.
The "GeoJava" Internet
Computing Model
This section
briefly addresses how the Internet Computing Model for Geoprocessing
can be implemented with Java to support ubiquitous geospatial data
and geoprocessing.
The
GeoJava Internet Computing Model is built upon the Global Network
Infrastructure and provides an extended service infrastructure
consisting of core geoprocessing services and application support
services. This service infrastructure includes Java Platform and
Jini, the foundation software technologies that enable distributed
GeoJava applications and services.
The
GeoJava Internet Computing Model supports a variety of GeoJava-based
elements that can be transported over the Net, namely: geospatial
data in the form of Java Data Containers; simple geospatial
components (objects) in the form of JavaBeans; intelligent
geospatial components in the form of Java Agents; geospatial
applications in the form of Java Applets; and hybrid versions
of these four types of elements, where geospatial data and software
are integrated, packaged and transported with non-geospatial data
and software.
Within "service
consumer" environments that implement the GeoJava Internet
Computing Model, service consumers can invoke GeoJava applications
on local workstations, via Web browsers with Java Applets,
or through thick-client or thin-client Java Applications.
Local service consumers can also gain access to Java Applications and Java
Servlets on local proxy servers. In more complex enterprise
settings, service consumers may also invoke extended enterprise
functionality over intranets and extranets. These capabilities
are implemented through component-based Enterprise JavaBeans and
through hybrid Java Applications and Java Servlets,
or they may exploit mobile computing services consisting of Java
Applets, Java Data Containers or Java Agents.
"Service
provider" environments that implement the GeoJava Internet
Computing Model can offer a variety of net-source GeoJava services.
These include: geospatial appliances that run Java Applications, Java
Agents and/or Java Beans; geospatial servers that run Java
Servlets and Java Applications, which access and serve
up geospatial and/or hybrid data (e.g. "Digital Earth"),
applets or beans; and specialized geospatial agencies that serve
up intelligent Java Agents.
In summary,
the GeoJava Internet Computing Model allows any geoprocessing or
hybrid application in any service consumer or service provider
environment to access any net-source GeoJava servers, data, applets,
agents or appliances.
