Digital Technology
Remote sensing – data collected from aerial photography and satellite imagery. Tem – System of satellites & receivers to plot location.
GPS – Global Positioning System – system of satellites & receivers to plot location.
GIS – Geographic Information System, - System to manipulate & display spatial data.
Electrical lines, gas lines, etc.
Remote Sensing
Aerial Photography
Discern spatial patterns
Resource Inventory
Emergency Management
Sun-Synchronous Satellites: adjust settings to highlight certain items
LANDSAT
AVHRR
Geostationary Satellites
GEOES (Weather)
GPS
Global Positioning System
24 satellites orbit earth every 12 hours
Satellites transmit pseudo random code
Time of signal to receiver gives distance
Triangulation gives location
GIS
Geographic Information System
System for storing, analyzing and manipulating spatially referenced data
Data consists of layers of one variable such as: vegetation, landforms, or soils
Layers can be overlaid/combined for analysis or display
Application include: resource management, planning, hazard assessment, etc.
Earth-Sun relationship
Most Physical Processes on Earth powered by incoming radiation from Sun.
Earth-Sun Relationship Complex – Depends on:
Latitude
Position of Sun in Sky
Time of Year
Earth’s Rotation/Axial Tilt
Our Place in Space
Big-Bang Theory
Milky Way Galaxy
Our Solar System
Shape of the Earth
Oblate Spheroid
Variation in Sun Angle by Latitude
Subsolar Point
The Sun
About 4.6 Billion Years Old
Average Star, Nothing special
100 times diameter of Earth
Powers most natural processes on Earth
8.3 min. for sun’s energy to reach Earth
Strong Magnetic Fields/Sunspots
The Earth follows an elliptical orbit around the Sun with its closest point at Perihelion and its farthest point at aphelion.
The Earth’s Rotation & Axial Tilt
The Earth’s Rotation around its Axis Counterclockwise Rotation around North Pole
Moon’s orbit around the
