| Zusammenfassung |
| Finding and retrieving space physics data is often a complicated task
even for publicly available data sets: Thousands of relatively
small and many large data sets are stored in various formats and, in
the better case, accompanied by at least some documentation. Virtual
Heliospheric and Magnetospheric Observatories (VHO and VMO) are being
developed to help researches by creating a single point of uniform
discovery, access, and use of heliospheric (VHO) and magnetospheric
(VMO) data.
The VMO and VHO functionality relies on metadata expressed using the
SPASE data model. This data model is developed by the SPASE Working
Group which is currently the only international group supporting global
data management for Solar and Space Physics. The two Virtual Observatories
(VxOs) have initiated and lead a development of a SPASE-related standard
named SPASE Query Language for provided a standard way of submitting
queries and receiving results.
Our presentation will demonstrate how the VMO and VHO use SPASE and SPASEQL
for searches based on various criteria as, for example, spatial location,
time of observation, measurement type, parameter values, etc. The results
can then be saved, downloaded or displayed as, for example, spatial-temporal
plots that quickly reveal where and how often was the searched-for
phenomenon observed.
We will also demonstrate how a local application, written in the IDL
programming language, can submit queries and retrieve results from the VxOs
by employing SPASEQL.
