The spatial data and
non-spatial data together with the developed application tool with GIS interface
can help the District Administration in various useful aspects like property
management. Which could be:
- Locating plot(s) belonging to person(s).
- Mutation of land based on various criteria.
- Faster updation and presentation of data (Spatial & Non-spatial)
- Planning of revenue generation.
- Planning of irrigation pattern.
- Land acquisition.
- Development of existing and planning of new structures.
- Finding of land use like residential, commercial, industrial, water bodies
etc.
- Generating of reports for higher officials / management with adequate maps.
- Generating a component for MIS at State/National level.
- Accessing the data at the fingertips.
MethodologyThe data utilised here could be divided into two groups
i.e. Non-Spatial auxiliary data and Spatial map data. The non-spatial data
should be in the form of external database, which facilitate the user to use the
same database for other application like MIS. In the present study, the database
is in ORACLE. The database is stored in deferent tables using the concepts of
RDBMS for faster and easier accessing of the data with proper multi threaded
security.
The spatial data conversion process normally begins with the
identification of the data source for the land base. These sources of
information may range from extremely accurate surveyed maps containing no ground
control references. Source data may also be existing in the computer files in
deferent formats. Before starting the creation of database the source data has
to be updated and verified so as to generate the accurate existing data. Some
times the data is not clear enough to distinguish the features, which create
problems for the operator and inaccurate data may get generated. As the
decisions of a planner are based on the data, the inaccuracy in the base data
may create problems to the planner too. So the maps has to be made
distinguishable before considering it as source data.
Detail of plots
in a village Bhola RawalIn the present case the spatial data is being
created using on-screen digitisation process of khasra level village maps (cloth
maps) and integrated with the digitised Survey of India maps. The cloth maps
those have been developed during the Chakbandhi are being considered to be the
source data, Chakbandhi happens once in twenty-five years. The cloth maps are
converted to the raster format images using the scanner and subsequently to the
vector format using the onscreen digitisation process. These vectorised village
maps are made error free with GIS tools and are geo referenced in respect of the
Survey of India Maps. An integrated single map is being generated from several
cloth maps. This makes the user to access all the village maps at the same time.
The next step that is being carried out is linking of the two databases
with the help of the plot nos. and village codes. This generated database can be
used for the making decision for the district administration using the developed
tool, which is capable of various automatic query analysis, thematic mapping,
report generation etc.
This front-end tool which is being developed can
be incorporated with regional languages so as to facilitate the user to use the
tool in user friendly manner for the planning. Here in the present case the tool
is using the Hindi language both for data updation and data representation with
query analysis.
ConclusionThe generation of the base map and
attachments of attributes not only help the administration but also to other
government and non-government organisations providing multiple usage of onetime
effort. The use of the front-end tool will help in improving the revenues as
well as the services benefiting time and economy.
