Weather Forecasting Department ( WF ) in IMD is concerned with Analysed Weather Charts, where all the charts are manually marked minutely with everydays events and weather parameters, this Research and Scientific selected on Daily basis and recorded in various RC's and RMC's .. [Read More]


DATA RESCUE SCHEME was necessary to be implemented because of the following reasons :-

  • ACCESSIBILITY - This Data was inaccessible because it was stored in various store rooms in random manner along with other Sheets of Data, it took weeks and sometimes months to trace a particular charts
  • To Search a specific Sheet it was impossible for the IMD officers to access the old data, so the officer were depended only on the latest 3-5 years of Data for Analysis and Research Purposes
  • VALUABLE DATA – this data of such great importance was lying unused
  • Since this Data was very old some Paper Sheets started Decaying and were deteriorating day by day and there was possibility of losing all the important Data
  • In future this Data can also be used by various other Governmental Bodies for their Research work and linked to their DataBases
  • This Data can also be used in Collaboration with other Global Community and Countries for better Analysis and Forecasting
  • VALUABLE FOR FORECASTING AND ANALYSIS – Once the data is Digitally Photographed, named and proper search engine be developed this valuable data would be made available to the Scientific Community just by the click of mouse

Condition of some of the Store Rooms was very critical

  • Digititalisation had to be done to urgently to stop the further damage of the Weather Charts
  • Since these DATA was there on Paper Sheets of various Sizes this Data had to be brought on Uniform Digital Format in a smart way where it could be accessed by a click of the mouse
  • Once the DATA is rescued a professional Search Engine could be developed to access and utilize these DATA
  • How did we photographed the charts that were torn, partially cut, eaten by termites ?
The Photographs that were torn, partially cut, eaten by termites were to handled in different way depending on the degree and way the Weather Charts were affected There were different procedure that were followed to revive the Maps, the procedure were as follows :-  
  • For Torn Maps or Maps eaten by termites
  • We had to first see or rather identify which part of the Map/Chart is eaten by the termite if the part containing the Date and height is missing the Map is useless but if the sign of the officer is along with the Date still the Map can be
  • First the Damaged or the cut Map/Weather Chart is to be sticked with the tape and than has to be mounted on the map holder stand which was specially designed to hold the chart against the blank back ground (i.e white paper as background) or base map which is exactly the same as a background
