2. CollabCAD CAD Group, National Informatics Centre
had been developing a 3D CAD / CAM Software called
CollabCAD
For Indian Strategic Sectors, like Space, Atomic Energy…
Registered in US Patent Trademark Office.
Based on OPEN Source / Libraries like:
OpenCascade, Java, Java 3D, PostgreSQL
CollabCAD runs on
Windows 95/98/NT/2000, Linux and Solaris platforms.

3. Genesis of CollabLand
Requests from various states like TN, Karnataka, Kerala for:
A software for drawing FMB Maps, to be incorporated in
the existing software for non-spatial Land Record Data.
A cost effective solution for deployment upto Taluk/Block
level, based on Open-Source technology
A system to provide the citizens, the Maps (FMB Extracts)
of their plots on demand at an affordable price.
A solution where the Government holds the technology,
for further enhancement and support.

4. Main Objectives Viewing / Printing FMB Extracts as a Citizen Service
Create FMB Maps from 5-Column Ladder Data
Viewing / Printing FMB Extracts as a Citizen Service
Perform Transactions like Sub-Divisioning & Merging
Provide integrated Solution with Non-Spatial Data

5. Salient Features Boundary and Adjacency information in Table format.
Facility to enter Ladder Data, Sub-Division Point Data,
Boundary and Adjacency information in Table format.
Drawing of FMB Maps from the above data with a
Single mouse click.
Saving / Restoring Maps into / from Database

6. Basic Features Option for Clockwise / Anti-Clockwise Traversal
Automated computation of Line Lengths from Tables
Computation of optimum text placement position
Option for Units for Data, like Meter, mm, Link, Feet
Extensive checks for input data validation

7. Basic Features … Interactive Modification and Moving of various Texts
Interactive Aligning with North Direction
Viewing / Printing of the Map of the Entire Plot or of a
Particular Sub-Division
Viewing / Printing to Standard Scales
Provision for Bulk Data Import to Tables from Flat Files

8. Sub-Division Features
Interactive Creation of Sub-Division Points / Lines
Creation of Sub-Divisions with a single mouse Click
Merging of Sub-Divisions
Automatic synchronization of input data in Tables
Display/Comparison of Actual and Displayed Area

9. Detailing Features 100+ scalable Symbols, Customisable (using XML)
Non-Aligned Symbols such as: Houses, Wells / Tanks
Notes : With modifiable Text sizes and Orientation
Fixed-Length Frill Lines for Adjacent Plot Boundary
Interactive Moving / Modification / Deletion of Details

10. Detailing Features … Free-Hand Sketches to represent Rivers, Streams,
Roads, Railway/Telephone/Telegraph/Electric Lines
Polygons with Hatching facility to represent Buildings
Polygon / Poly-Line creation with Constraints
Arrows with User-Specified Size

11. Display Features Option to display GPS Coordinates, Border / Title,
Sub-Division Area and Survey Number, on the Map
Display of Ladder / Extended Table on the Map at
the desired Location and Format
Control on Thickness of Lines and font Size of Texts.
Selective display of various Points and Lines

12. Display Features …
Interactive Zooming and Panning using Mouse / Key Board
Permanent / Temporary Rotation of maps to suit Printing / View
Provision for Page Setup: Working in Preview
Facility to set Standard Plot Scales

13. Workflow Workflow with 3 levels of participants :
Draftsman : Performs actual FMB modifications;
Forwards to Head Surveyor for checking
Head Surveyor : Checks modifications by Draftsman;
Forwards to Tehsildar for approval
Tehsildar : Finally approves the FMB Modification

14. Security Role Based User Groups – Tightly coupled with a
similar functionality in Database Management System
Role Based Menu – Dynamically Created from Database
Log maintenance of all Important events in the database.
Facility to View / Compare older versions of Maps

15. Mosaicing Plotting of Traverse Data to get Village Traverse
Importing of FMB Maps onto Village Traverse Maps
Automatic and Manual Positioning of FMB Maps
Moving / Rotating Imported FMB Maps
Automatic and Manual merging of Vertices / Sides

16. Miscellaneous Features
Unlimited Undo – Redo facility
Local Language Support – Using Unicode
Measuring Tool to get distance between Points / Lines
GUI Based facility for Database Backup / Restore
Report Generation using Jasper Reports
Lite Version for Public implementation (at Kiosks etc)

17. Why CollabLand ? 5 Good Reasons
Platform Independent : Works on Linux / Windows
Negligible cost : Due to use of Open-Source Tools
Caters requirements of various Survey Systems :
Ladder / FMB Data; Total Station Data (directly from Instruments); Shape File Data; Data from other Software
Integration with Non-Spatial Land Records Application
Modifiable Software – IPR is with Govt. of India
