GHY 104 1st Edition Lecture 24 Remote Sensing- Active remote sensing- System directs a beam of energy at a surface and analyzes the energy reflected Radar, LiDAR- Passive remote sensing- System that records energy radiated from a surface (like visible light, infrared) Landsat, GOES, IKONOSGeographic Information Systems (GIS)- Computer-based, data-processing tool for gathering, manipulating, and analyzing geographic information- A GIS combines spatial and attribute data- Maps can contain multiple data layers:- Physical features- Cultural features- Layers can be added to create composite overlayBiogeographic Realms- For large areas, we can distinguish regions based on large groups of plants and animals that haveco-evolved there.Terrestrial Biomes- An Ecosystem is a combined assemblage of all plant and animal communities and their abiotic environment.- A biome is a large stable terrestrial ecosystem characterized by plant and animal communities. - Specific plants and animals are called indicator species.- Biome Examples:- Equatorial and Tropical Rain Forest- Midlatitude Broadleaf and Mixed ForestThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- Midlatitude Deciduous- Midlatitude Grasslands- The biome concept attempts to define large regions by their biota (especially plants.) The classification system is closely related to climate. Earth’s Major Terrestrial Biomes- Equatorial and Tropical Rain Forest- Tropical Seasonal Forest and Scrub- Tropical Savanna- Midlatitude Broadleaf and Mixed Forest- Needleleaf Forest and Montane Forest- Temperature Rain Fores- Mediterranean Shrubland- Midlatitude Grasslands- DesertsArctic and Alpine
