Aerial Surveys

Our path breaking survey methodologies change the very way in which surveys are done. Drones are flown in pre defined paths and a large number images are captured, stitched and used to produce quick, accurate visual survey information of the site. The time taken is reduced to a great extent, resulting in reduction of overall project costs. Survey outputs are highly accurate and comparable with traditional survey methodologies.

Orthomosaics – Various images of the site are stitched together after orthorectifying to form one single image of the site, which can be overlaid on Google Earth. Further, accurate distance, area and volume can be measured using the orthomosaic. The orthomosaic can be imported into third party software for further analysis.

Digital Elevation Models- The entire site can be converted into a colour coded digital elevation model which helps understand the elevations of different sections/points of the site. The DEM can be can be used for further analysis such as for generation of slope models which help in calculating the amount of water flow in that particular region. This can be used to design rainwater harvesting structures and drainage systems.

Object Counting – Our object counting algorithm scans the orthomosaic to count the number of a particular type of object, for example – trees, that are there in the image. This is especially useful for plantations and estates who would like to assess the number of shading/plantation trees that are there at the site.

Contour lines – Contour lines of the site can be generated as required. This is especially useful for visualising elevations and planning earthwork, foundation work, sewage, water works etc.

Boundary Marking – Marking boundaries of real estate sites accurately is critical to ensure security and legality of properties. We mark and identify boundary points on the orthomosaic and draw the boundary around using these markings, giving accurate drawings and perimeter/area measurements. These can be geo-referenced with pin point lat-long and digitally archived as well as digitally shared.

3D Models – The images are converted into a 3D model which help with realistic visualization of the site. The 3D model can be annotated and used for project planning.

3D Point Cloud – The 3D model is converted into a 3D point cloud, with each point representing a unique point inthree dimensional space. These points are defined by X, Y, and Z coordinates. Further, the point cloud can be imported into third party software for further analysis. The points can also be exported into a .xyz file for further processing.
