deegree - Components and Framework for SDI
URBAN AND TOWN PLANNING
The processes of urban and town planning
require integration of a variety of
data sources as well as the distribution
of planning information to a wide audience.
Integration of data is possible
using two methods, one being the
usage of raster information that still is
the rule, although much information is
lost this way. The second method is the
exchange of object-structured information
that is theoretically superior but in
practical projects still the exception.
Distribution of the information can
best be done using the Web, therefore
application of geoportals and corresponding
standards like WMS and WFS
seem necessary. A number of deegreebased
projects in Germany and the
Netherlands address these issues.
Major problems were identified regarding
the integration of data while applying
the approaches described above.
While raster integration seems technically
unproblematic, existing data
often does not satisfy basic requirement
like proper georeferencing or
common application of styling rules.
While an object-oriented approach
seems much more satisfying and standards
like GML are by now able to scope
with the necessary complexity, the
practical problems here are still hard to
overcome. Using deegree a prototype
implementation of an object-model
(XPlanGML) based planning information
system was developed under the
name XPlanung Publishing Platform.
In the future, the development and
application of object models for planning
purposes and the coupling of 2D
data with 3D city models will be major
themes handled by deegree.
ENVIRONMENTAL INFORMATION SYSTEMS
Almost all environmental information
is geospatial information and can best
be analyzed when displayed together
with other georefenced data. Although
environmental information systems
include additional aspects ,they benefit
greatly from an SDI approach. SDI
allows integration of distributed data
PROJECT DESCRIPTION
Vietnam is the destination for the new century and
Ho Chi Minh City is the biggest city in Vietnam.
Because of its fast growth, tourists and explorers
will find this website useful. There is a detailed
map of Ho Chi Minh City with streets, land marks,
rivers, buildings, hotels It's possible, if you have an
account, to bookmark your own points of interest
on this map. There is also statistical information
about the administrative unit of Ho Chi Minh City
including population, area, education and other
things. (Text taken from http://www.opengeospatial.

What is MIDAS?
MIDAS is a 'one-stop shop' for companies and
online services needing easy and efficient online
access to weather information.
What MIDAS Does
MIDAS provides online access to a rich set of
dynamic weather forecast, satellite nowcast and
marine environmental information for easy real-time
integration into third-party end-user applications
and web services. MIDAS provides two simple to
use IP-based APIs to support the inclusion of its
content: (i) a simple HTTP-based OGC-compliant
interface, and (ii) an XML-based interface supporting
more complex data retrieval requests.
ProSiN
The planning portal of Hamburg offers the public
information about planning data - both the current
legally binding development plans which can be
downloaded as PDF files as well as development
plans being still in process. The portal is based on
WMS, WFS-G and WMC standards. The citizen
can navigate via a gazetteer enabling a search via
street and house number. The next step is the integration
of participation module based on WFS.

sources, their analysis and display. deegree-
based systems can be coupled
with tools such as iReport to handle
environmental reporting tasks.
DISASTER AND RISK MANAGEMENT
The application SDI this technology to
disaster management poses several
challenges, the two most important
being reliability of the overall system
and integration of up-to-date sensor
information. An approach to this is
under development in a joint German-
Turkish research project called EDIM
(Earthquake Disaster Information System
for the Marmara Region, Turkey),
funded by the German Federal Ministry
for Education and Research. The architecture
of the system is based on standards
developed by the OGC e.g. WMS,
WFS and SOS. The software components
used in the project will mainly be
taken from deegree, so that transfer of
project results to other regions with
similar disasters will be easy and costeffective.
Transferability and fail-proof
strategies and dynamic integration of
sensor data linked to cartographic display
will be cornerstones of the project.
PROFESSIONAL SERVICES
deegree is a commercial Open Source
project in the sense that lat/lon bases
its business model mainly on services
about deegree. Although a number of
other institutions are contributing to
the deegree project, the majority of its
development still is done as part of
lat/lon's projects. The services offered
by lat/lon include development of project
solutions, consulting and coaching
for institutions using deegree and support
of businesses who want to develop
solutions and products using deegree.
CURRENT STATUS
In June 2007 deegree day took place in
Bonn Germany. At the same time, the
2.1 releases of deegree were published.
The corresponding demo releases are
extremely easy to install as they come
as WAR-archives and can be deployed
within seconds if a Tomcat Servlet
engine is available. The demo releases
include a WMS, a W Fs (with gazetteer),
a WCS, a Catalogue Service-Web (for ISO
metadata), a WTS. All demo releases
come with preconfigured data sources
and detailed documentation. The
release 2.1 is a major step forward
in deegree's development. Visit

regarding deegree day 2007 and deegree
releases.
