Looking forward
ESRI has made major investments
in the development and implementation of open GIS standards,
not only to serve our own customers but also to promote
sharing geographic data across all GIS platforms. We believe
our continuing investments in open technologies and participation
in organizations will result in increasingly open and interoperable
GIS solutions.
The following initiatives are some
of the areas in which ESRI is concentrating its efforts
with regard to standards and interoperability. When available,
these technologies will be downloadable from the ESRI Interoperability
Technology Download Center.
Enhancements to
the OGC Web Map Service Connector for ArcIMS
ESRI is enhancing the WMS connector
for ArcIMS to support a Styled Layer Descriptor (SLD). The
Open GIS Consortium, Inc. (OGC), SLD Web Map Server component
responds to requests for a Web map service to produce maps
of georeferenced data.
The SLD component allows features
from a Web feature service to be retrieved and allows a
user to set explicit styling information in order to render
a map. Users will also be given the capability to dynamically
request features that are rendered on top of existing map
layers.
The SLD component of the OGC Web Map Service Connector for
ArcIMS will be available in the spring of 2003.
Enhancements to
the OGC Web Feature Service Connector for ArcIMS
The OGC Web Feature Service connector
for ArcIMS allows a client to retrieve spatial data encoded
in Geography Markup Language from multiple Web feature services.
The OGC specification defines two types of Web feature services,
basic and transactional. A basic WFS, currently implemented
as the OGC Web Feature Service, implements the GetCapabilities,
DescribeFeatureType, and GetFeature operations. A transactional
Web feature service supports all the operations of a basic
Web feature service and, in addition, implements the transaction
operation and, optionally, the LockFeature operation.
The OGC Web Feature Service Transactional component will be
available in the spring of 2003.
ArcGIS Interoperability
Toolkit
ESRI will provide add-ons to the
ArcGIS Desktop products (ArcView, ArcEditor, ArcInfo) that
allow Web mapping client applications to access multiple
OGC WMS, OGC WFS, and Registry services. The client applications
include ArcGIS applications such as ArcMap and ArcCatalog
(for ArcView, ArcEditor, and ArcInfo), JavaServer Pages-based
HTML applications, and Java-based applet or desktop clients.
The ArcGIS Interoperability Toolkit will be available in the
spring of 2003.
