GRASS Development with Eclipse / CDT
In the Distant Early Warning System (DEWS) Project
Peter Löwe
GeoForschungsZentrum-Potsdam, DRZ, Telegrafenberg, D1473 Potsdam, Germany, Contact: ploewe@gfz-potsdam.de
The tsunami disaster affecting the Indian Ocean region on Christmas 2004 demonstrated
the short-comings in tsunami detection, public warning processes as well as intergovern-
mental warning message exchange in the Indian Ocean region. The Distant Early Warning
System (DEWS) Project - aims at strengthening the early warning capacities by building
interoperable tsunami early warning systems.
Of special importance is the distant communication of warning information among warning
centres. The project complements the German Indonesian Tsunami Early Warning
System-Project (GITEWS).
DEWS provides a Reference Model for
interoperable tsunami early warning
systems and applies the Service
Oriented Architecture (SOA) paradigm.
Based on an Enterprise Service Bus
(ESB) all resources (e.g. sensors) can
be decoupled from proprietary access:
•A Service Layer provides uniform
access to resources
•An Orchestration Layer to access
workflows and processes for the early
warning phase.
The ESB concept is used in both the
upstream and downstream part of
DEWS.
Motivation
GRASS GIS is a valuable tool for complex data manipulation. It is often applied in the backend of a project
to generate spatial data resources to be used with other software tools. The DEWS project requires
siginifacnt amounts of spatial data resources. To establish reasonable production capacities, it is vital to
have specifiv GRASS versions easily available on various platforms, preferably on different operating
systems.
Approach
GRASS developers can use integrated development environment (IDE) for efficent code development and
software deployment. For this, the example of Eclipse in conjunction with the C-Development Tool (CDT) is
used. It can be used to show how to access, manage and compile the GRASS sourcecode independently
from the platform via the IDE.
Larger Picture
For developers the short-term benefits of this approach are extended options for collaborative development,
code refactoring and the wrapping of the traditional building-chain in ant-Code.
The Potential
In the last years, IDEs have
increasingly become the standard
approach to code development. Most
programmers have become used to
them and take them for granted. To
lower the curb to join the active
GRASS developer community and to
extend and rejuvenate the
community in the long term, IDE-
based platform-independent
GRASS-development will play a
prominent role in the future. This will
help to future-safe GRASS GIS as a
community-driven FOSS GIS project.
as represneetd in the Eclipse IDE. The frame in the middle shhows the ant-Code fragemnt which is used to execute the gRASS build process. The front shows
ware as it was called up right from the IDE.
