Bharat Net Phase-II will be completed by 31 March 2019 to connect the remaining 150,000 village councils covering 325,000 villages. Once all the gram panchayats have been connected by the dedicated fibre optical network, the last mile connectivity to all villages will be provided by the commercial telecom operators by expanding the current national network of 38,000 Wi-Fi hotspots to 700,000 Wi-Fi hotspots to cover all 625,000 villages in India.
To accurately map such a large rural road network of Bharat Net OFC project, ‘Prashant Surveys’ has provided the Mobile LiDAR Mapping service for more than 2,200 Km in 6 blocks of the Chhattisgarh Infotech Promotion Society (CHIPS) project in Chhattisgarh.
We have the capacity to survey about 200 Km of road network per day using our Two numbers of ‘Leica Pegasus Two’ mobile LiDAR Mapping Systems. Accordingly, we can easily complete the data capture of about 5,000 Km rural road network for the Bharat Net project in one month. The data processing and feature extraction of the same can be completed in about two more additional months using our existing in-house strength of data processing teams, software’s and infrastructure.
1) Mobile LiDAR Data can be collected with the speed of vehicle varying from 10 Km / hour up to 80 Km / hour (for rural roads). Ideal vehicle speed maintained by us is usually 30 to 40 Km / hour depending upon the condition of the rural roads.
2) Each run of Mobile LiDAR can easily capture about 150 m corridor (i.e. 75 m on either side of the run) with dense 3D point cloud data, 360 degrees panoramic view camera data and GNSS / IMU data. Usually single run is sufficient for capturing data for rural roads in such OFC projects.
3) In one day, about 80 Km to 100 Km length Mobile LiDAR data can be easily collected by 'Leica Pegasus Two' on a two-lane rural road with single run depending upon the condition of the rural roads.
4) The raw data collected on site is so dense (about 1 GB data collected for 1 Km length of highway) that it has to be downloaded into external hard disk and transported to the head office for further data processing and feature extraction, from the registered 3D point cloud data.
5) LiDAR data processing and registration on 3D point cloud is done using 'Leica Auto Process' software, whereas the feature extraction of point, line and polygon features are done using multiple licenses of Leica Map factory software. Final delivery of 3D topographic plan can be made in Arc GIS shape files or AutoCAD Dwg files & MS Excel files as per the requirements of the client. Some sample deliveries are enclosed for reference.
