3D Map
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.
