highly interactive and efficient mechanism to access,
view and process geophysical datasets in a large project.
5. Implementation Example
The GIS Project Manager component has been success-
fully implemented in a seismic refraction data processing
software, which is a three stage application for picking
arrival times, computing refractor model and finally cal-
culating statics. A new project is created and all project
datasets and processing parameters are defined into its
database. Using the GIS or Project Explorer any dataset
can be interactively opened and processed according to
the predefined job sequence (Figure 3). In this way the
Project Manager acts as an efficient data management
tool in handling large seismic exploration projects. An-
other advantage of the Project Manager is that once all
datasets have been defined in its database, there is no
need to load them over and over again. Whenever the
project data needs to be viewed or reprocessed, simply
loading the project database provides full access to all
defined datasets.
6. Conclusions
A GIS Project Manager component is presented which
can be used by geophysical software applications dealing
with seismic refraction, gravity, magnetic or electrical
resistivity data. It provides a user-friendly interface for
managing large geophysical exploration projects with
several datasets and processing tasks. Datasets are ac-
cessed directly from the GIS, without using the conven-
tional menus, thus saving a lot of user time. In addition
the geographic location, type and status of all datasets
involved in the project are directly shown on the GIS,
which provides a complete picture of the project in terms
of spatial distribution and processing status. The GIS
based Project Manager is an effective and efficient tool
for interactive and integrated data management of large
geophysical projects.
