The Global Positioning System uses an array of near earth orbit satelites and a fancy radio in the hand to help you find out where on earth you are. Remote Sensing uses on satelite to take a picture from space so that Farmers can see what is growing on their land. It is also used by Governments to identify the extent and severity of damage from earthquakes, floods, volcanic eruptions.

EzraGPS, or Global Positioning System, is a satellite-based navigation system that provides precise location information. Remote sensing involves the collection of information about an object or phenomenon without making physical contact, typically using sensors on satellites or aircraft. While GPS provides location data, remote sensing captures various forms of data such as images, temperature, and vegetation cover.

Which of geographys three key questions can the technology of remote sensing help us to answer?
Remote sensing technology can help us answer the question "where" by providing precise location information through satellite imagery and GPS. This technology allows us to map the Earth's surface, track changes over time, and monitor natural disasters or environmental changes from a distance.
What is geodesy?
Geodesy is the science of measuring and understanding the Earth's shape, rotation, and gravitational field. It involves techniques such as satellite imagery, GPS technology, gravity measurements, and remote sensing to accurately determine the size and shape of the Earth. Geodesy is crucial for activities like map making, land surveying, and monitoring movements of the Earth's surface.
How scientists explain the arrangement of the world map as you know today?
The arrangement of the world map is based on a combination of historical exploration, cartography, and geographic data. Scientists use technologies like satellites, GPS, and remote sensing to accurately map the Earth's surface. The Mercator projection, commonly used in world maps, distorts the sizes of landmasses to create a flat representation of the curved Earth.
How is an elevation map measured?
An elevation map is usually measured using remote sensing techniques like LiDAR or radar to capture the topography of the Earth’s surface. These methods use sensors to calculate the distance between the Earth's surface and the sensor, creating a detailed map of the elevation at various points. GPS technology can also be used to determine elevation by measuring the position of a receiver on Earth's surface in relation to known elevations elsewhere.
What are tools used to study the biosphere?
Some tools used to study the biosphere include satellite imagery to monitor land use changes, weather stations to track environmental conditions, GPS technology for mapping ecosystems, and remote sensing devices to measure air quality. Additionally, scientific instruments like microscopes, DNA sequencers, and spectrometers are used to analyze biological samples and understand ecosystem dynamics.
