Digitising cadastral land records paves a roadmap for planning and development. Recognising this, the state of Uttarakhand is gearing up to usher in a new era of g-governance by initiating modernization of its land records
At present we are living in the decade of e-governance and the next decade would be of g-governance. G-Governance requires a huge GIS infrastructure and the need of the hour is to formulation of a roadmap for development of GIS infrastructure of land records. To sensitize the users about making land records GIS-ready using the latest geospatial technology, Center of Excellence for Natural Resources Data Management System in Uttarakhand (COE, NRDMS), Department of Geography, Kumaun University SSJ Campus Almora and the District Administration Pauri recently brought together key stakeholders in the state to provide them hands-on training and exposure to the technologies.
The Centre of Excellence (COE), NRDM in Uttarakhand, Department of Geography, Kumaun University started work of GeoPortal development for one of the districts of Uttarakhand, viz., district Almora in 2009, with the help of the financial and technical support of the Department of Science and Technology, Government of India and technical support of the Department of Computer Science, IIT Mumbai and School of Information Technology, IIT Khargpur. GeoPortal provides single window service for accessing data/information with digital map of a targeted region/area/place by clicking few mouse battens in the computer. The Almora GeoPortal is a web-base GeoPortal which is tagged with India GeoPortal established at the NSDI, epartment of Science and Technology Government of India, New Delhi which shall also be tagged soon with the UCOST, Dehradun for the use of State and district level planners/administrators of the Uttarakhand State. Different line departments can access information with digital maps through a single window by clicking two/three mouse buttons in computer.
Mosacking of cadastral maps
The first step for modernization of cadastral maps through GIS technology is mosacing of all the cadastral sheets of one village through computer. Normally there are 5 to 15 cadastral sheets of one village. The users got a demonstration on how to mosaic all the cadastral sheets together to get a village map in raster form through computer.
Data capturing by GPS
The second step of modernisation of cadastral maps is registration of cadastral village map in GIS software through geo-referencing technique. For geo-referencing, coordinates (i.e., latitudes and longitudes) of the village are required but these are not available on the cadastral maps, therefore, coordinates of different control points of the village are required by GPS. How to get the coordinates of different control pints of a village through GPS? How to geo-reference cadastral map using coordinates (i.e., latitudes and longitudes) captured by GPS? During this technical session, participants were given hands-on training on data capturing through GPS.
Geo-referencing of cadastral maps
The third step of modernization of cadastral maps is registration of village map on WGS84 projection in GIS software using ground control points, captured by GPS. This step is also known as geo-referencing. Hands-on training on geo-referencing of cadastral map was given to users. For hands-on training on geo-referencing, an open source GIS software was used by the participants.
Digitization of cadastral maps
The fourth step of modernization of cadastral maps is transforming the data of cadastral map in to GIS software in vector format. This process is known as digitization. During this session, participants learned practically how to convert spatial data, i.e., point, line and polygon of cadastral map in to vector form in the GIS software using digitization technique.
Data integration on digital cadestral maps
The fifth step of modernization of cadastral maps is integration of Khasara data, i.e., plot number and details of their ownership. This process is known as integration of non-spatial data in the GIS software. In this session, the participant learned practically the process of non-spatial data integration with the all three forms of spatial data, i.e., point, line and polygon.
Hands-on training on land data integration
Discussions and recommendations
After deliberation and discussions in this session, the Pauri district of Uttarakhand has decided on the following decisions for modernization of cadastral records and for developing GIS infrastructure of the entire district Pauri:
– A GIS cell shall be established for Development of District GIS for Pauri District at Vikash. The GIS Cell shall function under the control of the District Magistrate and the Chief Development Officer Pauri shall be the Nodal Officer for GIS development of Pauri District. The objectives of the GIS Cell shall be:
• To modernise the cadastral records of district Pauri;
• To develop GIS infrastructure of each line department as per their own needs;
• To make applications of GIS in planning, project implementation, monitoring, management and in administrative works;
• To update district GIS at monthly, bi-annually and annual basis through the concerned departments;
• To make efforts for capacity building of the district for GIS development.
– For smooth functioning of the GIS Cell and for monitoring of GIS activities in the district, a District Coordination Committee shall be constituted.
– To begin with:
o two rooms (one for GIS Lab and other for displaying GIS Maps of the district) and two computers for GIS lab shall be provided by the district administration
– For developing GIS Infrastructure, one GIS Technician shall be provided by the COE, NRDMS Kumaun University for a period of one year only, after that government shall make arrangement of GIS technician and Analyst for updating the Pauri GIS; and
– COE NRDMS, Kumaun University shall extend technical support by providing on-job training to the Officers of District Pauri for their capacity building in GIS development and applications.
– The Heads of all the line departments shall be the Nodal Officer of their own department for GIS development
– To review the progress of the development of Pauri GIS, the DCC meeting shall be held bi-annually or as and when required.
– To develop Uttarakhand GeoPortal, GIS Development Working Group-was formed. All the participants of this workshop shall be member of this working group.
