Prasanta Kumar Pramanik Digitization of Mouja Map & its integration with RoR in WEST BENGAL [Presentation at NLRMP workshop on 24-25th Sept 2008] Prasanta Kumar Pramanik Senior Technical Director National Informatics Centre Government of India

Agenda Digitization of Mouja Map Updating a map Integration of digital map with ROR Computerised Map Services to citizen

Digitization of Mouza Map A brief past of Land Records & Maps in West Bengal Land records prepared as per Permanent Settlement Regulation in 1793 First series of cadastral maps [CS maps] prepared in 1888 – 1940 2nd series of cadastral map [RS maps] prepared in 1954-1962 under Revisional Settlement Operation 3rd series of cadastral map [LR maps] are being prepared by updating RS maps since 1972 & is nearing completion

LR Mouza Map ( scanned copy)

LR Mouza Map All the Mouza maps are prepared following a scale Total No of Mouza: 42041 Total Mouza maps: 67,436 All the Mouza maps are prepared following a scale Scale: 16’’= 1 mile (1:3960) mostly also 32”= 1 mile (1:1980) & 64’’= 1mile (1:990)

The Digitization Process of maps involves (i) Scanning of maps using precision scanners (ii) Redrawing points, lines, polygons on image of map-also called layers (iii) Topology building (iv) Data integration (v) Map composition from different layers and (vi) Integration on Bengali Script for labeling

Inclusion of various non-map features as A digital updatable Map is developed by the composition all the components listed Point layer Line layer Area layer and Inclusion of various non-map features as legend the label of the map bata plot information various geographical features (the alamaths) / conventional signs, in-situ points which are represented by symbols and integration on Bengali Script as label

Output of Digitization process Print Copy of Map Softcopy in .SHP format along with all relevant image files & dbf files and other files related to non-map features

Plot Extraction

Plot-2360 is being extracted for division

Single Plot Plot-2360

Creating a bearing Node Plot-2360 Node-13: 60 ft from node 5 & 35 ft from node 6

Creating a perpendicular Node Plot-2360 Node 14: At a perpendicular distance of 35 ft from line 6,12 at the point 12

Creating Parallel Node Plot-2360 9 Nodes 15, 16 Parallel to line 8,9 at a distance of 25 ft

Joining Nodes Plot-2360

Calculating Area Plot-2360 System calculated area: .0481 Acre

New Plot Plot-2360 A new plot 3462 is created from 2360

Completion of updation of Map New plot is placed in the Mouza map

BHUCHITRA Integration of Mouza map with ROR text data

BHUCHITRA: Functionalities Village level Land Records Management Cadastral Mouza Map Management Map enabled Query/MIS report generation Generation of derivative maps Citizen Services On-line Up-dation of Land Records & Map * Administration

BHUCHITRA Village/ Mouza Based Information Map enabled query/MIS report shows query results shown on the map itself. Cadastral Mouza Map based information includes displaying a mouza map, showing plots owned by a raiyat, coloring plots with specific land class, area, possession , owner

Mouza map information can be available from the main menu of the BHUCHITRA

Interface to select a particular Mouza for which information is required

On selection a mouza map is displayed On selection a mouza map is displayed. The map can be zoomed in or out by pressing buttons

The zoomed out view

On clicking a particular plot within the map plot details are displayed with a different color mark along with owner(s) details

In the ROR information option any plot number can be searched within the map in enlarged view and adjacent plots will be shown.

The plots with a specific range of area (in acre) can be displayed with a different color mark.

The plots of a specific land classification can be viewed in the map The plots of a specific land classification can be viewed in the map. Different land classifications can be viewed in the mouza using different color legends.

Different types of Possessor existing in the plots can be viewed using different color legends on selection of the type of possessor.

Map information details with relevant court fee is displayed along with normal ROR copy.

Plot maps with table of measurements for a khatian is shown and be printed use Laser printer for delivery to citizen.

Generation of Map Service to Citizen Plot Map along with the neighboring plots Printing of Mouza Map in pdf format with 1:1 scale Printing of zoomed image of a plot showing dimensions of the sides of the polygon
