geography, the study of the diverse environments, places, and spaces of Earth ’s surface and their interactions. It seeks to answer the questions of why things are as they are, where they are.
May 24, 2024 · Light spreads outward in all directions when it is emitted from the Sun. As the light spreads, its intensity upon reaching distant locations decreases. The intensity of light decreases as the square of the distance between the Sun and receptor increases, a relationship known as the inverse square law.

- Location. Most geographic studies begin by learning the location of places. Location can be absolute or relative. Absolute location: Provides a definite reference for locating a place.
- Place. Place describes the human and physical characteristics of a location. Physical characteristics: Includes a description of such things as mountains, rivers, beaches, topography, climate, and animal and plant life of a place.

Apr 27, 2024 · The solar radiation that makes its way through the atmosphere and to the surface is called insolation. The amount of insolation received at the surface depends on 1) the sun angle, 2) day length, 3) ground slope, 4) path length, and 5) the state of the atmosphere.
- Sensor Types. Remote sensing uses a sensor to capture an image. For example, airplanes, satellites, and UAVs have specialized platforms that carry sensors.
- Types of Remote Sensing. The two types of remote sensing sensors are: Passive sensors. Active sensors. ACTIVE SENSORS. The main difference between active sensors is that this type of sensor illuminates its target.
- The Electromagnetic Spectrum. The electromagnetic spectrum ranges from short wavelengths (like X-rays) to long wavelengths (like radio waves).
- Image Classification. When you examine a photo and you try to pull out features and characteristics from it, this is the act of using image interpretation.

May 24, 2024 · A portion of the incoming solar radiation is absorbed by the surface and a portion is also reflected away. The proportion of light reflected from a surface is the albedo (a). Albedo values range from 0 for no reflection to 1 for complete reflection of light striking the surface.
