Regional Data Centre
|
Keeping
pace with technological development, Regional Office Data Centre (RODC) in Bhopal was set
up with financial assistance from the World Bank. It utilizes state-of-the art
technologies for the purpose of processing, storage and dissemination of data in a
systematic manner. |
RODC houses the Data
Processing Centre (DPC) and the Data Storage Centre (DSC).
Similar Data Processing and Storage Centres have been established in different
organiations at several places with a National Data Storage Centre in NewDelhi. This is a
part of the HIS (Hydrogeological Information System) which has been envisaged to integrate
the countrywide data bases so that they can be disseminated to the different users.
In DPC, the field data are computerized
and subjected to 2 levels of validation, primary and secondary including hydrogeological
validation. Other activities of DPC are analysis, processing and reporting. Here the data
is stored in temporary data bases. At the end of hydrogeological year, once the data has
been properly validated, processed (authenticated), data is transferred to data storage
center.

GWDES (Ground Water Data Entry System)/GEMS (Groundwater Estimation and Management
System): CGWB has been using GWDES since 1999 for computerisation of historical
data. It has a MSAccess Database at the back end. Front end has been developed using VB.
It has modules like WQDES (for Chemical data) and DATAAnalyst (for harmonic analysis
etc.). Recently data already entered in GWDES has been converted into dedicated software
GEMS. Dedicated software (GEMS) Groundwater Estimation and Management System(GEMS) has
been developed by M/s TataInfotechLtd. for CGWB. This software uses industry standard
RDBMS (Oracle). This is essential for long-term sustainability as well as safety of the
data sets. Necessary features like data security, protection from data correction and
provision of controlled accessibility is part of the system design. An efficient and user
friendly query system helps in data retrieval. GEMS includes GIS support to visualize and
analyse spatial data. GEMS facilitates data entry, processing, validation and
dissemination of periodic or annual report. The data analysis tool provided in GEMS has
all the capabilities of spatio temporal analysis of hydrological data. Several methods of
multivariate statistics, timeseries and geostatistics have been provided. Most of the
generally used variograms used in spatial statistics have been developed in the system.
Various interpolation techniques including Kriging has been included. Different modules
like grainsize analysis, fence diagram for strtigraphic correlation, water quality data
analysis, geophysical profiling/ sounding data handling and analysis have also been
provided. The data-capture module handles all sorts of spatial data collected from
landscape elements from toposheets,satellite data, and attribute data such as: Well-site
details,Geologic,geomorphologic descriptions,Assembly,Aquifer data, Well-log
lithology,geophysical logs, Well performance and hydraulics, Water quality, Rainfall,
Depth of water table and Ground water abstractions. The statistics module of the
application identifies inherent characteristics in the observed data, which is essential
for appropriate model identification and use. Spatio-temporatl Data analysis tools have
been provided.
Data Storage Centre
Data Processing and Data Storage
functions are separated. Data Processing and validation is a technical task for which
hydrogeologists/ geohydrologists are qualified. Whereas final data storage i.e. library
function is the domain of data base managers. This distinction is absolutely necessary for
number of reasons. Processing and storage are different disciplines, which require
different expertise, tools, hardware support, activities and responsibilities. To
guarantee discipline in building the data base and its sustainability in the long run. To
make sure that for design and decision making data are being used which passed all steps
of validation To avoid mixing of fully processed data and data under processing To ensure
compatible database configuration by all agencies To mainatain a professional data
security system For an easier upgrading/ replacement of either data storage or data
processing tools in case of new development. Data Storage Centre provides information on
spatial and temporal characteristics of water quantity and quality variables / parameters
describing the water respurces/ water use system in all the states. It provides a valuable
and convenient source of information for decision / policy makers. At the DSC metadata
will be available about the data stored in the database. Data that flows are of the
following types: Hydrgeological Data Field data Authenticated data Object data Temporary
data Metadata MIS data GIS data
