What are the differences between ground based research methods and remote sensing research methods?
Bryokd
In remote sensing, aircraft or satellites provide the platforms for sensing applications. The primary difference is that in the remote sensing methods, a lot more area can becovered in a very short period of time than with ground-based methods. There are details that cannot be resolved by the remote methods that can be determined on the ground, but there are trade offs with the two methods of investigation. More and more sophisticated way of "looking" at the ground from remote platforms continue to be developed. The location of South American temples hidden in the jungle is just one example of the capability of the remote platform.

What is the difference between active and passive remote sensing systems in geography?
Active remote sensing transmits energy to allow an image to be formed. Passive remote sensing collects energy reflected or emitted from a surface. Active systems direct a bean of energy at a surface and analyze the energy reflected back. An example of active sensing would be a radar. Passive systems are pretty much what the eyes see, and it's like a photograph. Passive sensing radiates visible light.
What is remote sensing and GIS?
Remote sensing is the use of technology to gather information at a distance (i.e. without making contact with the object). For example weather radars that detect incoming rain fronts at a distance are a form of remote sensing. GIS is an acronym for geographical information systems. These are methods of compiling, sorting, analysing and presenting the geographical distribution of differing types of data. For example you could plot time variations in rainfall data against differing geographical locations.
What is term for the process of gathering information through images taken at a distance?
Remote sensing
How is active remote sensing different from passive remote sensing?
Passive remote sensing picks up wave lengths of the light spectrum occurring on their own such light in photography. Active remote sensing will send out a wavelength of the spectrum and measure how it bounces back like radar.
What is the opposite from remote sensing?
In situ?
What are some methods of remote sensing?
ground surveying
What research methods do geographers use?
Geographers use a variety of research methods, including fieldwork, remote sensing, GIS (Geographic Information Systems), cartography, surveys, interviews, case studies, archival research, and statistical analysis. These methods help geographers collect, analyze, and interpret spatial data to better understand patterns and processes in the natural and human environment.

What are the differences between sensing perceiving and thinking and how do they relate to the observation process?
when we take in data w/o preconceptions we are sensing; when we focus on particular sensations and catergorize them according to our memory system, we are perceiving; and when we draw conclusions about their patterns and meaning, we are thinking. (thinking for yourself 29) you sense a ball coming straight for your face, the sensing goes from the eyes to the brain, your brain percieves this message and turns it into a thought. therefor you are observing this and your brain is organizing. ge 104/114- critical thinking and problem solving, exercize 1

What was selnium used for in the past?
From research in 1873 it was found that electrical resistance of grey selenium was dependent on the ambient light. This led to its use as a cell for sensing light
Importance of remote sensing in civil engineering?
remote sensing
When was Sensing Murder created?
Sensing Murder was created in 2003.
