Maps advantages Easier to use, easy to care around, provide an easy to use reference when collected into an Atlas, can show the earths entire surface or just a small part, can show more detail, and can present info about a wide range of topics; physical and cultural features. This error arises from the three-dimensional aspect of terrain features and is seen as apparent leaning away of vertical objects from the center point of an aerial photograph.

While aerial photography connotes images taken of the visible spectrum, sensors to measure bands within the nonvisible . A geographic information system (GIS) is a computer system for capturing, storing, checking, and displaying data related to positions on Earth's surface. Satellite imagery can be passive or active. Because of a constant scale, vertical photographs are easier to interpret than oblique photographs. history notes These satellites maintain different altitudes, inclinations, eccentricities, synchronies, and orbital centers, allowing them to image a wide variety of surface features and processes (Figure 4.14).
