10. Integration of map with RoR
10.1 Each plot of land is represented on the digital map as a closed polygon. Such polygons are identified by a unique 5 digit number, that is, its plot number. In the RoR database, such plot numbers are referenced. This provides a basis for integration of digital map with the digital RoR data. The RoR database consists of several related tables (7 main tables and several master tables) of information that provide ownership, land classification, etc. information which are essentially text data types. All the tables are connected by two common data fields. These are:
Idn: a seven digit code to identify a Mouza (2-digit for District, 2-digit from Block & 3-digit for the Mouza)
Plot No.: a five digit Plot number
10.2 For digital map, data (contained in more or less 36 files) are distributed in three tables under various columns having the above two common fields (Idn. and Plot No). Shape files (.shp, .shx and .dbf) are binary files, and are stored in BLOB data format -- a facility available in the MS-SQL Server 2005 DBMS. The existing RoR database is added along with the above three tables containing map information to form an extended database of RoR.
10.3 Data, both spatial and textual, are used by the application software “BHUCHITRA” (developed by the NIC, West Bengal State Unit) to provide the necessary integration of data. Such integration provides all the flexibility to manipulate textual data and spatial data without any constraint and provides a platform for various improved citizen-centric services and MIS reports. Some of them are given as follows:
1) Providing plot map (parcel map), showing dimensions of each side and area along with the RoR.
2) Generating various derivative maps based on possessions, classifications, legal sections applicable, size of the plot, etc.
3) Generating analytical reports on area in the RoR with respect to the digital map so as to help in data correction, both text as well as map.
4) Integrating the RoR updation with its map updation.
