Atomic Minerals Data Centre (AMDC) is responsible to meet all the IT related needs of the Directorate.
The major activities of the group are as follows.
AGRS Data processing
In
its earlier incarnation as Central Data Processing Unit (CDPU),
established approximately 30 years back, the center started
developing computer programmes for processing Airborne Gamma
Ray Spectrometry (AGRS) data, generated from routine AGRS survey
conducted by the Directorate. The data processing technique
developed by the group is in conformity with IAEA Technical
Reports Series No.323 published in 1991. Various computer programmes/
softwares and their objectives developed in this regard are as follows:

presently available in the data library.
Database development
Database
development is another major field, the center is mostly engaged
in. Beginning
with a modest development of a database (LOGIC-D) for borehole
logging data and (INDUGEO) for U-occurrences
in India, the group is presently involved in collecting, classifying,
synthesising and storing data in databases for easy retrieval. The
geoscience database on atomic mineral exploration was designed
and developed in paradox software at AMD headquarter, Hyderabad. The
same was deployed at all regional centers where database is
being populated. Works are at hand for design and development
of geoscience database in oracle under 3-tier architecture.
In
addition, a number of utility databases have also been developed
for various in-house applications.
Local & Wide Area Network
AMDC
presently operates a network of computer comprising a number
of network servers with operating systems such as Windows NT,
LINUX and AIX. Through ISDN connectivity communication
between headquarter and various regions is established. This
facility is in use on regular basis for exchange of reports,
maps, research papers, and other information between various
units of AMD.
Web designing
AMDC has
been entrusted with the
task
of design, development, promotion and updating of AMD's website
depicting all the activities of AMD. It is responsible
for updating all the information on the site on a regular basis.
Anunet
Data
center is actively collaborating in the VSAT based ‘ANUNET’
project of DAE. ANUNET provides satellite-based communication
between all major centers of DAE. It has two data channel and
a voice channel. To provide seamless voice connectivity, EPABX
exchange of AMD has been configured with ANUNET. AMD library
server is also connected to LAN and ANUNET. Data center has
provided network and ANUNET connectivity to its server. Users
can browse library information for their routine requirements.
A
video conferencing system has been setup to communicate between
various DAE units using VSAT based connectivity. Data encryption
technique is being used for secure communication during video-conference.
Map digitisation and data integration using GIS
Digitisation
of geological maps and its integration with spatial data has
been one of the major works taken up by the data center since
1997. The digitised maps are being used for exploration activities
and geo-technical investigations. Nearly fifty maps in various
scale have so far been digitized covering large areas of the
country. Spatial databases for Geochronological and Geotechnical
data have been created and integrated with the geological maps
using GIS packages.
