It can be locality, town or empty area. Reconnaissance survey is done for a large area that is why various routes can be find. But the main purpose of … Read more
Digital elevation model is very popular 3-dimensional computer graphic technique that represents elevation of various objects in a single frame. In short form, it is known as DEM. Digital elevation model is used to to represent various terrains with its objects. DEM is used to creates elevation of planets and satellites such as moon and … Read more
Drone survey is a new technology in the construction industry. In drone surveying aerial data is collected cameras and downward-facing sensors. Basically this type of survey is used for terrain assessments and mapping. Drone survey is very fast compared to traditional survey techniques. It can make very precise maps and survey points. There are some … Read more
A topographic survey finds all features of a property’s surface and delineates all-natural features and heights. Essentially a 3D map of 3D properties showing all-natural and man-made features and improvements. Specifically, it shows position, size, height, and height changes. A topographic survey is usually based on systematic observations and is published as a series of … Read more
Post Processed Kinematic (PPK) is a GPS correction technique used in surveying that collects, uploads, and then modifies location data. The data is corrected after it is gathered and uploaded. Real-time kinematics (RTK) is another type of correction technique, such as PPK, that performs real-time data and image correction. PPK technology is commonly used for … Read more
