deegree - Building Blocks for Spatial Data

Markus Müller

Abstract


deegree1 is a Java-based Open Source / Free Software
framework for the implementation of Spatial
Data Infrastructures (SDI). It contains the services
needed for SDI (deegreeWeb Services) as well as portal
components (deegree iGeoPortal), mechanisms
for handling security and access control issues (deegree
iGeoSecurity) and storage / visualization of 3D
geodata (deegree iGeo3D). deegree is conceptually
and interface-wise based on the standards of the
Open Geospatial Consortium (OGC) and ISO / TC
211. At the time of writing it is the most comprehensive
implementation of those standards in one Open
Source framework. The framework is componentbased
to a high degree, allowing the flexible creation
of solutions for a wide variety of use cases. deegree
is the official reference implementation of the OGC
for the Web Map Service and Web Coverage Service
standards. It is published under the GNU Lesser
General Public License (LGPL).
