Development of GIS for Pradhan Mandhri Gram Sadak Yojana Roads

Date of Start:July 2004
National Institute of Technology, Trichy (R, S)

Scope and objectives
To create Graphical User Interface (GUI) of the Tamilnadu rural road network which can be in the data format compatible to the requirement of users involved in rural development.

Methodology

The core network and habitation details have been collected from DRDA. The spatial and non-spatial data were integrated in GIS environment.

Findings and Conclusions

(i) Using this GUI, we can determine proximity between features (roads and villages).
(ii) It is possible to summarize the fields eg. total length of particular (MDR, VR) road category.
(iii) We can combine the information from each table and simply search one location. This function also allows bringing in      database files (dbf) from other sources and connecting them to maps. Using this function, new data can easily be      appended in the database.
(iv) We can retrieve data specifically by using query option.
(v) Using “Spatial join” function, one can get more precise information about total new construction.

The present information system can be effectively used for fast and specific data retrieval. It can also serve as an efficient tool for decision making.
