In order to facilitate the integration of the attribute data (ROR) with the cadastral maps
NIC has finalised a product using geotools for various operations like storage of the
maps, fast retrival of the plots, display of a plot related to owners and updation of plots
because of mutations. This tool is named as “BHU-NAKSHA” and is developed using
open source java library called “GeoTools”. This tool caters to all basic necessities of
Patwari with regard to the cadastral map or land parcel management.
Digitisation and Scanning Process
For each village (one or two) cadastrals map sare available at Tehsil records rooms. It is
very essential to convert them to electronic formats for further processing and records
keeping process.Various steps involved in the digitization work are as under:
Examination and availability of Cadastral Maps
Digitization of Cadastral Maps depends upon availability of maps, their sizes, quality of
maps, scale, features, availability of grid points, S/W or color status, media used, etc.
hence in the first step it would be required to examine availability of the same and
evaluate them for further processing.
In areas, where cadastral maps are not available or Cadastral maps are in bad quality or
land pattern has changed, survey/re-survey using modern technology of surveying &
mapping is proposed. In such cases a policy decision is to be taken for conducting fresh
survey (De-novo Survey).
Appointment of a Nodal Officer, Formation of QC Team, Single point of contact, Setting
up of tolerance limit (depending upon the source map) should be finalised for the Tehsil.
Indexing & Coding
All the village maps may be indexed to the standard numbering/naming convention and
the same should be used for scanning and further activities. This should enable to keep
track of all sources in proper order.
All sheets have to be indexed with appropriate index number. The index number is to be
generated using the village metadata with respects of the various administrative codes
(state, district, tehsil, revenue inspector/patwari circle/mouza and village code). The
index number should be a unique number with information of the administrative
hierarchy of the village. Census Codes may be used for sheet indexing.
The source condition, legibility and completeness should be checked. If any
discrepancies are observed with source material, they should be referred back to Land
Records Department for replacement or clarification.A “Village Index of Survey Sheets”
is to be prepared. This process will help in effective monitoring and verification strategy
of the project.
