The needs for natural resources management have widely recognized; the ever-increasing population leads to pressure on the available resources that exceed their carrying capacity. Resources degradation through erosion of valuable layer of the earth surface changes in flow regimes of rivers and other phenomena are frequently the worse events facing by the present day world. To date, however, the management of natural resources seems to have had only a limited impact in abating these adverse processes.

The lack of adequate information on which mineral resources management is based ,has identified as one of the reasons for this limited impact. It is in relation to this point that discussions on information systems to support resource management were initiated.

Thus the role of information system in mineral resources from the perspective of userís present-day needs is tremendous. This approach is thought to be essential, as only the use of the information produced by Information Systems can justify their existence

Present work is a step in this direction ,an attempt is being made to develop a Mineral Resources Information System based on generic principal of data base management system using Digital Image Processing and Geographical Information System

Mineral Resource Information System is a database for mineral deposits, In this paper I have taken an example of a metallic deposit (iron and manganese ore) of Iron Ore belt, Keonjhar and Singhbhum region, Orissa and Jharkhand state, and non metallic deposits (Lime stone) of Raipur Chhattisgarh state, India. M.R.I.S contains all relevant information on mining activities of the region. Although it is developed based on the concept of Remote Sensing and Geographical Information Systems, and runs independent of any commercial GIS, Remote Sensing software and allows data updating, querying and report generation with Digital Image Processing and GIS Capabilities

The non-spatial database includes information on deposit, production, chemical composition and mine environment. The spatial database contains latest remote sensing data layers such as Indian Remote Sensing Satellite, IRS-LISS-III, LANDSAT-TM, and ERS-1-SAR. The spatial database also includes place location, mine location, drainage, road network, DEM, Slope, Aspect, Geology, and Lineament map of the region.

Digital Image Processing is used in any panacromatic Digital data and save in TIFF,JPG,BMP,IMG file format

The database is designed such that mine location and Settlement location map can be displayed together with one of the spatial data layers. At each mine locations by clicking of a mouse, all details about mining, production, chemical composition, and environment will be displayed in tabular form, which can also be generate and displayed in bar chart, pie chart etc.

Most importantly, there is a security feature, so that with only password permission the database can be edited and updated. Additionally, there is option to link advance GIS and Remote Sensing packages, if available in the system.

Thus the MRIS aims to provide all basic informationís vis-ŗ-vis spatial data layers related to the mining and geology of the Singhbhum-Keonjhar region for metallic and Raipur for non metallic deposits. The target users could be decision makers, academicians, researchers or even general public seeking to know all about mineral deposits of the region.

The software design is based on hierarchical file structure where inputs are the real data. In the MRIS, one can update and retrieve the information from the database. Both spatial and non-spatial databases are used as inputs. If the inputs are changed only in the core then database can update the data where ever it is being shared, but this change can be done by authorized users.In M.R.I.S software spatial data are displayed in the back ground and non-spatial data is displayed in the fore ground, which makes it is possible to make multiple queries. M.R.I.S is Commercial GIS and Remote Sensing software independent, however, it be linked to other GIS and Remote Sensing software if available in the local machine, Multi windows option for comparative study is also available for research, Software uses mostly Microsoft resources (Excel, Access and Word), MRIS is developed using Visual Basic 6.0.

Thus the main objective of the project is to an upgrade this advance version of M.R.I.S version 1.0 to M.R.I.S version 2..0 .which can perform independently some digital image processing techniques like user defined filters and Enhancement

Thus objective of the project is to establish an Operational Information System supporting specific requirements of mineral resources studies. It is designed to allow manipulation of data by means of intelligent quarries and to provide information in different forms i.e draft reports, deposit profiles, graphs spatial, temporal analysis, quality analysis, reaserve etc. for mineral .It can also be used for other types of spatial prediction in which the goal is to predict the probability of occurrence of point objects. To make user friendly, on line menu driven system and also in CD-ROM with extensive validation built to ensure data.

The geological and other data that are used to describe a deposit on a Mineral Information System . These are grouped into header data (deposit identification), host rock data, ore body data, sample data, data reference with respect to Remote Sensing and Geographic Information System and to acquire data for Mineral Information System. Three approaches are used, namely digitizing and capturing of existing data (completed), capture of data on a commonly basis of specialized mineral resources studies and data capturing during metallogenic mapping of selected areas.It can be easily accessible for multi-national, interdisciplinary research and for mineral industry.

It is concluded that the outcome of this project can be utilized for further development in extracting various valuable minerals with minimum wastage and at a nominal investment for an overall economic development of the area The study demonstrated that an information system with spatial and non-spatial information can be developed and can be used by clients without expensive commercial GIS packages.

In the present case only for preparing spatial data layers, GIS and DIP packages were used. For data access, display, query and updating of non-spatial data,& some image processing for spatial data, MRIS can be used.The system can be packaged and given to users who can update the database and use it as per the needs.
