Drones for Mapping

Drones are the real deal when it comes to mapping out terrains. This is why they have already proven so popular in construction, civil engineering and real estate footage. Urban planning and development can also benefit from the high capacity and output of these tools.

For mapping road, railway and highway networks, drones offer faster, cheaper and safer alternatives. They feature low maintenance, minimal staffing requirements, rapid deployment times and a variety of sensors hat can offer diverse and comprehensive information. These are a few specific benefits of drones for mapping.

Benefits of drones for mapping

LiDAR mapping

Have you come across discussions of the use of this technology for autonomous vehicles? LiDAR works in a similar way to radar, but offers more precise digital imaging. It uses a central laser source to emit beams of light across all directions, which then are collected by a sensor. By adjusting for the speed of light for a round trip by a single light beam, LiDAR can be used to develop a real time 3D map of the findings.

While LiDAR technology features heavier equipment than a lot of other sensors, large enough drones can ferry and use it to present more accurate maps. The precision imaging supported by LiDAR is bound to present high quality and more accurate output.

Volumetric measurements

Without the support of automated assessment tools, mapping revolves around human input which may be subject to approximation. For instance, ground-based surveyors would need to measure stockpile elevation after every 5 or so feet to determine the volume of a large heap. The outcomes are based on approximated results, since they may not be able to fully factor in alack of consistency in shape. They could also beat a higher risk of harm, especially if the material involved could be dangerous.

Drones can carry out volumetric assessment within minutes. Their outcomes are as a result of accurate measurement and tabulations, with results likely to be determined quickly. For instance, a drone that can generate a digital surface model and provide topographical information on the stockpile above would significantly cut out assessment time and provide more accurate findings.

Cadastral surveying

Drones can help provide cadastral imaging solutions, which would help address the need for this type of imaging during the legal creation of property. Drones make mapping and land survey easier by identifying and defining boundaries and land features that could help improve the accuracy of these efforts. As an added benefit, drones are more cost effective than alternative measures such as hiring out a helicopter for the purpose. When fitted with the right imaging equipment, they can even offer multiple views that could address the high cost of the service.

Automated mapping

With the help of control points, such as known coordinates and placed markers, drones can take autonomous images along a calculated flight path. You would only need an operator to ensure this was carried out effectively. Drones can be used for automated mapping, reducing the high staffing needs of the task. Instead of several staff members taking days to map out an area, a drone could effectively provide the same output in a single controlled session.
