What is a DEM file?
A DEM file is a type of data file that stores information about the elevation of the earth's surface at regular intervals. It can be derived from various sources, such as satellite imagery, aerial photography, or ground surveys. A DEM file can be used to create a digital representation of the terrain, which can be visualized in different ways, such as contour lines, shaded relief, or 3D models.
How does a DEM file work?
A DEM file works by dividing the area of interest into a grid of cells, each with a specific size and location. Each cell has a numeric value that indicates the average height of the terrain within that cell. The higher the value, the higher the elevation. The values are usually stored in meters or feet above sea level. By using a DEM file, a software program can calculate the slope, aspect, and curvature of the terrain, as well as the distance and direction between any two points on the map.
