Tacheometric Surveying: Principle, Procedure, and Advantages
Tacheometric surveying is defined as a method of angular surveying in which a tachometer is used to determine the horizontal and vertical distance between two points. Thus, eliminating the tedious process of chain surveying to measure horizontal distance. Tacheometric surveying ...
Types of Maps in Drone Mapping
Drone mapping or aerial surveying in construction provides the end deliverables in the form of maps. The two common types of drone mapping methods are photogrammetry and LiDAR. Both the methods give different mapping outputs and require specific data processing ...
Drone Surveying: Features and Applications
Drone surveying is an aerial survey conducted using drones and special cameras to capture aerial data with downward-facing sensors. It is frequently used by surveyors and engineers in construction for terrain assessments and mapping. Drone surveying can be 90% faster ...
Difference Between RTK and PPK Surveying Technology
Real-time kinematic (RTK) and post-processed kinematic (PPK) are GPS correction technologies that collect the location data, identify the errors, and make corrections during drone surveying. RTK technology provides real-time correction when the data is collected, while PPK corrects the location ...
What is Post Processed Kinematic (PPK) Survey?
Post processed kinematic (PPK) is a GPS correction technology used in surveying that corrects the location data after it is collected and uploaded. Real-time kinematic (RTK) is another type of correction technology like PPK but performs real-time corrections to the ...
What is Real-Time Kinematic (RTK) Survey?
Real-time kinematic (RTK) is a surveying technology that measures the relative positions using two Global Navigation Satellite System (GNSS) antennas in real-time with better accuracy. The errors found in GNSS results are determined and corrected using RTK technology. This article ...
Important Parts and Working of Digital Theodolite
A theodolite is an instrument used to determine the relative position of points on the earth’s surface by measuring the horizontal and vertical angles. Theodolites can be either digital or non-digital types. Digital theodolites are more convenient and accurate as ...
