Surveying and Mapping

Using drones in surveying is probably the fastest, most accurate and versatile way of capturing and delivering large area results in the shortest amount of time. Drone data is becoming more accepted in land departments for cadaster as well as a tool to capture the first survey before the project begins.

Zain Drone UAV technology is capable of capturing high-resolution images (no less than 24 megapixels) for the purpose of aerial surveying and mapping with images that are georeferenced with exceedingly high accuracy using Real-Time Kinematic (RTK) and Post-Processing Kinematic (PPK) methods. Processed data can be represented as a high-density point cloud, high-resolution orthomosaic, high vertical accuracy DTM (digital terrain model) as well as contour lines generation, DSM (digital surface models), 3D mesh or wireframe.. 

Use cases

  1. Corridor Mapping
    UAV corridor mapping projects in roads, railways, powerlines, utilities and other linear structures and locations, delivering high-quality orthophotos, 3D mesh and point-cloud models that can be used in verifying as-built data as per design and create construction progress reports or fault reports on assets.
  2. Topographical Mapping
    Traditionally mapping large areas with land surveying equipment has been an intensive process that required teams of people to be deployed in the field. Drone technology transformed the way that land surveys are now conducted, providing the means to quickly map large areas and provide visual information that was previously only available through full-scale aircrafts. Additionally, extracting accurate DTM (digital terrain model) data from large data sets to accurately identify topography and produce contour lines has become an automated process that previously took days or months of manual processing.
  3. Construction
    Drone technology is not new to the construction industry. As the size of projects increases, there is a growing need for tools capable of surveying large construction sites in an enormous amount of detail. Drones enable detailed construction progress monitoring through visual and accurate surveys and inspection of structures very quickly, safely, and accurately. Multiple measurements can be taken from the same data set, reducing the number of surveyors required at construction sites and improving the speed of data collection and reporting.
  4. Mining & Volumetric Mapping
    Drone-based material volumetric surveys are visualized in 3D, allowing users to quickly understand the inventory as well as periodical cut and fill. This allows for greater control over the work of subcontractors, project orders, and material needs. As UAV technology has been evolving rapidly and numerous improvements have been made in the way data is verified, UAV-based volumetric surveys have achieved greater accuracy than the conventional land-based volumetric surveys due to the data density produced by advanced camera payloads.
  5. 3D Models
    Reality modeling by UAVS is an invaluable way to visualize the third dimensionality of an object of interest. The result is usually a fully functional 3D building model in common formats that can be imported into a number of 3D visualization applications, which can then be used across various verticals such as media, communications, smart cities, architecture and design.
