DroNepal just lately carried out a number of hydropower mapping tasks in remotes areas of rural Nepal to check the potential and feasibility of utilizing drones for surveying.
Situated between India and China, Nepal is planning to develop hydroelectric dams to assist energy its financial system and export electrical energy to neighboring nations. Nepal’s Division of Electrical energy Improvement has issued licenses to just about 400 personal corporations for surveys and electrical era tasks.
Final yr, DroNepal was named the winner of WeRobotics’ first Enterprise Incubation Program. The corporate acquired $75,000 to review using drones in mapping and surveying hydroelectric amenities in distant areas of Nepal’s troublesome topography.
WeRobotics operates a worldwide community of labs to speed up and scale the impression of humanitarian help, international improvement and environmental safety efforts utilizing drones and different robotic options. The group has workplaces in Wilmington, Delaware, and Geneva, Switzerland. Over the previous three years, WeRobotics has carried out dozens of aerial robotics and coaching missions internationally.
Based on DroNepal, there’s nice potential for drone-based survey work in Nepal as a result of shoppers want correct knowledge and visualization supplies for his or her hydropower tasks. The corporate stated its shoppers additionally want higher methodologies to satisfy data-accuracy necessities.
One of many areas surveyed utilizing drones was the within the neighborhood of the Hairabkunda Khola Hydropower Station the place numerous hydropower amenities have been closely broken or destroyed by an earthquake in 2015. DroNepal accomplished survey work that can be used to assist reconstruct hydropower era within the space.
Different areas surveyed by DroNepal have been the Liping Khola, Kalinchowk, Hongu Khola and Lukla hydropower stations. In a single occasion, the period of time wanted to finish topographical surveying utilizing a drone was lowered from one week to 2 days.
DroNepal stated the development of a hydropower station requires several types of land surveying work, together with: feasibility reconnaissance surveys for preliminary planning; geological and environmental surveys; entry street surveys; detailed topographical development surveys; and follow-up surveys throughout development.
The corporate stated drones are particularly helpful for mapping and surveying in Nepal as a result of nearly all of areas the place hydropower amenities are situated may be obscured by vegetation, timber and heavy forest. In such instances, drones can present topographical info reminiscent of digital floor fashions and contour maps.
DroNepal famous that knowledge seize is difficult in some areas of Nepal due to poor GPS alerts—particularly when a river is bordered by hills on each side. This requires guide pre-flights to find out the utmost distance a drone can fly with out dropping the GPS sign.
