Bheemdutta drone survey and mapping

The technical team from Geovation Nepal carried out an airborne survey in two wards (Ward 04 and Ward 18) of Bhimdutta Municipality. The obtained high resolution images were used to generate a high resolution orthomosaic, Digital Elevation Models. A geodatabase that includes natural and manmade features such as building footprints, road lines, openspaces was prepared through these outputs to prepare topographic maps, Landuse maps. These results were used for house survey, humanitarian open space mapping and to identify present condition of roads within two wards.

High resolution survey of an Urban municipality

Changu Narayan Municipality, an urban municipality in Kathmandu, approached Geovation to deploy our long-range drone to rapidly capture high-resolution drone images of the entire municipality. The work had to be carried out  within nine days as the site was close to the  airport. However, due to the ongoing COVID cases in the country, the imposed lockdown provided a limited traffic air space for easy deployment of the drones. Within 9 days, a 42-megapixel high-definition RGB sensor captured 11,000 images covering a total area of 64 square kilometers. The municipality later used those images with other tech consulting companies to generate street names and household numbers and also used them as baseline imagery in the open data portal. 

Drone based aerial survey of Phewa Lake

Geovation Nepal carried out an aerial survey using a drone to capture high-definition, geotagged images of Phewa Lake and its surroundings. Our team processed these images in image processing software to produce orthomosaics and elevations. Then, the obtained results were further analyzed and used to identify, demarcate, and map the Phewa Lake boundary in the MUTM (Modified-UTM) system.

High altitude Trail mapping and Surveys

Mt. Cho- Oyu (8201m) in the Khumbu Himalayas under the Mahalangur Range is the fifth highest mountain in Nepal and the sixth highest in the world. Located in Nepal and the People’s Republic of China, this mountain is one of the most popular mountains for mountaineering tourists. Hundreds of climbers apply for the permit to climb this mountain every year, the technical aspects of this mountain are full of diversity, making it the choice of mountaineers. In this regard, a recce trip was made to explore the area prior to the technical team’s task. A team led by the representatives of the Ministry of Culture, Tourism, and Civil Aviation, the Department of Tourism, the Nepal Tourism Board, and the Nepal mountaineering Association headed to the region for the aerial study. A drone pilot and a photographer accompanied the team for visual documentation.

The aerial recce trip was conducted to understand the terrain of the mountains in order to identify the safe mountaineering route for commercial mountain climbing. The route which mountaineers follow from the Nepal side has very little ascent, is technically difficult and has had cases of accidents with casualties. The team also projected an orthophoto map that identified big cracks and possible risks in the route.

Hyderabad, India – Drone Based Aerial Survey

The firm had successfully completed its first international project for Hyundai Motor Company in India. The project objectives were to conduct drone based aerial surveys for capturing high resolution imageries for a construction site. Furthermore, to use the collected images to generate 2d models i.e Orthomosaic, DSM and DTM as well as 3d point cloud and 3d model, finally converting the processed data to CAD compatible format for designing and construction of the new manufacturing plant.
