GPS enabled rugged tablets have now managed to completely revolutionize contemporary construction mapping and surveying processes. Professional, survey-grade levels of accuracy allow construction managers to obtain necessary measurements with a handheld device that can record accurate map and survey data in the field.
Real-Time Kinematic (RTK) satellite navigation Global Positioning Systems (GPS) establish tight parameters for accuracy. When combined with rugged tech the centimeter level accuracies of measurement can be deployed for either primary mapping or ground control when deploying drones. Drone mapping incorporates aerial photogrammetry, enabling tablet users to rapidly take multiple photos which can be analyzed and incorporated into the bigger picture.
Once imaging of a site is complete, software that reconstructs three-dimensional images of the terrain can be employed. Subsequently, the RTK GPS refines the accuracy of aerial data (accurate to 3 meters) down to an accuracy of mere centimeters by matching, positioning, and verifying the real world coordinates of the data points.
Survey-grade accuracy is essential to contractors working on building sites, but the time involved in standard surveying (and its dependence on worker availability, equipment transport, and more factors) can make this task difficult to accomplish on a tight deadline.
Deploying rugged tablets and drones can significantly reduce the time needed to accomplish for surveying and mapping, particularly in rough terrain where rapidly collecting accurate data is doubly difficult. A task that would typically take hours can now be completed in 20 minutes by combining the RTK GPS capability of rugged tablets with speed and penetrability of drones.
These rugged tablets contain the storage, computing power, and software to quickly complete mapping procedures with the survey-grade accuracy essential to documenting building sites. The results are certifiable and can be used to drive construction planning forward quickly, even in areas that are hard to reach or which have rough terrain that must be worked around.
Conducting surveying or mapping with rugged tablets and drones also opens new possibilities for an entirely new avenue of remote analysis. This technology provides ways for architects, main constrictors, subcontractors, site managers, and construction crews to integrate smoothly with city, county, and state governments.
Utilities can benefit by sharing and integrating information to correctly mark pipelines and underground wiring based on previous GPS mapping, minimizing risk of interference. In addition, rugged tablets are user-friendly, providing time and cost savings by allowing operators to be trained quickly and efficiently. Implementing accurate mapping via RTK GPS enabled tablets and drones is the future of surveying.
