Fourth generation digital land surveying refers to the latest advancements in technology used for land surveying. It involves the use of advanced equipment such as Drones, RTK and 3D scanners (LiDAR) to capture highly accurate and detailed data about the land.
A 3D map is a three-dimensional representation of a geographic area, showing the height, depth, and width of the terrain. It is created by using elevation data and satellite imagery to create a model of the area. 3D maps are useful for a range of applications, including urban planning, architecture, and outdoor recreation. They can provide a more detailed and accurate view of the area than traditional 2D maps, allowing users to better understand the topography and layout of the landscape. With the advancement of technology, 3D maps are becoming more widely available and accessible, allowing for more efficient and effective decision-making in various fields.
DTM
What is a DTM map?
Digital Terrain Models (DTM) sometimes called Digital Elevation Models (DEM) is a topographic model of the bare Earth that can be manipulated by computer programs. The data files contain the elevation data of the terrain in a digital format which relates to a rectangular grid.
