DRONE MAPPING AND SURVEY IN ARUNACHAL PRADESH

Digital Terrain Map

What are the benefits of the Drone Survey in Arunachal Pradesh?

Less Time & Less Cost- Capturing topographic data with a drone is up to five times faster than with land-based methods (like total station ) and requires less manpower. With PPK geo-tagging, you also save time, as placing numerous GCPs is no longer necessary. You ultimately deliver your survey results faster and at a lower cost.

Provide accurate and exhaustive data

Total stations only measure individual points. One drone flight produces thousands of measurements, which can be represented in different formats (orthomosaic, point cloud, DTM, DSM, contour lines, etc). Each pixel of the produced map or point of the 3D model contains 3D geo-data.

Map otherwise inaccessible areas

An aerial mapping drone can take off and fly almost anywhere. You are no longer limited by unreachable areas, unsafe steep slopes, or harsh terrain unsuitable for traditional measuring tools. Do not need to close down highways or train tracks. You can capture data during operation without any difficulties with other operations.

Where you can use drone mapping?

Land surveying/cartography

Survey drones generate high-resolution orthomosaics and detailed 3D models of areas where low-quality, outdated, or even no data, are available. They thus enable high-accuracy cadastral maps to be produced quickly and easily, even in complex or difficult-to-access environments. Surveyors can also extract features from the images, such as signs, curbs, road markers, fire hydrants, and drains. After post-processing with photogrammetry software, these same images can produce very detailed elevation models, contour lines, and break lines, as well as 3D reconstructions of land sites or buildings. For eg Drone Survey in Arunachal Pradesh is far easier compared to hilly terrain.

Land management and development

Aerial images taken by drones greatly accelerate and simplify topographic surveys for land management and planning. This holds for site scouting, allotment planning and design, as well as final construction of roads, buildings, and utilities.

These images also provide the foundation for detailed models of site topography for pre-construction engineering studies. The generated data can also be transferred to any CAD or BIM software so that engineers can immediately start working from a 3D model.

As data collection by drones is easily repeatable at low cost, images can be taken at regular intervals and overlaid on the original blueprints to assess whether the construction work is moving according to plan specifications.

Precise measurements

High-resolution orthophotos enable surveyors to perform highly accurate distance and surface measurements.

Stockpile volumetric measurements

With 3D mapping software, it is also possible to obtain volumetric measurements from the very same images. This fast and inexpensive method of volume measurement is particularly useful for calculating stocks in mines and quarries for inventory or monitoring purposes.

With a drone, surveyors can capture many more topographic data points, hence more accurate volume measurements. They can also do this in a much safer way than if they had to manually capture the data by going up and down a stockpile. Since drones are capturing the data from above, operations on-site won’t be interrupted. The short acquisition time enables capturing a site snapshot at a specific point in time.

Slope monitoring

With automated GIS analysis, it is possible to extract slope measurements from DTMs and DSMs generated by drone imagery. Knowing the steepness of the ground’s surface, the areas can be classified and used for slope monitoring purposes, including landslide mitigation and prevention.

With orthomosaics taken at different times, it is possible to detect changes in earth movement and to measure its velocity. This data can help predict landslides and prevent potential damage to roads, railways, and bridges.

Compared to traditional monitoring techniques, where sensors are placed on single points, drones enable more comprehensive data collection. Drones with PPK capability, which do not require laying out of multiple GCPs, are optimal for this application since these areas are often hard to reach or even dangerous.

Urban planning

The development of increasingly dense and complex urban areas requires intensive planning and therefore time-consuming and expensive data collection. Thanks to drones, urban planners can collect large amounts of up-to-date data in a short period and with far less staff. The images produced in this way allow planners to examine the existing social and environmental conditions of the sites and consider the impact of different scenarios.

Thanks to 3D models, buildings can also be easily overlayed onto their environment, giving planners and citizens an experimental perspective of a complex development project. 3D models also allow analysis and visualization of cast shadows and outlooks/views.

 Accuracy of Drone Survey?

The quality of camera resolution, the height at which the drone flies, and the method and technology used to geolocate the aerial images can heavily influence the accuracy of drone survey mapping. At this point, it is possible to reach an absolute accuracy down to 2-5 cm.

Drone Survey Methodology?

Before leaving the office for the Drone Survey, the team initially preliminarily surveyed with Google Earth to check the obstructions and site accessibility.

After reaching the site, the team started by putting the DGPS base and taking the RTK values at regular intervals. Drones capture aerial images after picking all the values across the area of interest. With the help of photogrammetry software like Pix4D or Agisoft, dgps, and drone data are merged to form a seamless orthomosaic or 2D map. You can achieve an accuracy of up to 2-5 cm.

Cost for Drone Survey in Arunachal Pradesh? 

Getting a Drone survey is extremely cost-effective. However, the cost of doing the Drone Survey in Arunachal Pradesh depends on various factors like the type of terrain, outputs of the drone survey, weather, etc. However, the Drone survey costs around Rs 60,000 to 75,000 per sq km.
