NECTAR has signed a Memorandum of Understanding (MoU) with National Highways Authority of India (NHAI) to provide specific benefits of UAV ultra high resolution aerial images in various stages of National Highway projects. NECTAR has covered more than 1400 km of linear stretch of highways in different parts of India through UAV imaging and processed the data into various high precision 3D mapping products. The benefits of drone mapping are useful for every activity of Highways viz planning, construction, monitoring quality and traffic congestion & toll management. Accurate feasibility study with respect to proper alignment preserving suitable geometry, economy of construction, land acquisition detail etc can be done through the above 3D mapping products. High Resolution Orthophoto & DEM generated from UAV data was generated which are very useful for the consultant engineers in most of the activities. The technology can provide significant amount of benefits in respect to save Time & Cost in planning and monitoring activities of National Highways.
In the areas of construction monitoring NECTAR has showcased by mapping 71 km of Eastern Peripheral Expressway for estimation of earthwork involved, measurement of width & length and monitoring different layers of pavement under construction stage etc provide a transparent & easy mechanism of monitoring the progress of highway projects. NECTAR has covered 60 % of its length for monitoring of expressway for its quality in regards to international standard for TOT awardees. The major highways covered so far is 100 km of Hyderabad-Vijaywada Expressway, 187 km of Kundapur-Goa highways along west coast, 241 km of National Highway No-8 in Gujarat-Rajasthan and 477 km of National Highway No-5 in Andhra Pradesh-Odisha along east coast.
