Help answer the question about Remote Sensing
How can I obtain images of vegetation in specific area by remote sensing?I want to study types of plants in place where it is difficult to reach, Is it possible to identify plants from images obtained by remote sensing ? How can I obtain such images on my computer?

Remote sensing (see the reference for a detailed description) is used for safety (say, to monitor the conditions within the crater of an active volcano), to cover a large region or to get a larger view (weather satellites in orbit), and when it isn't possible to perform more direct observation (for example, everything we know about the star Sirius or the core of the Earth is necessarily through remote sensing because we can't yet go there).
Here is what may be THE major source on the subject. The IRIS program was the CLEARS (Cornell Laboratory for the Environmental Applications of Remote Sensing).

I have spoken with people in the program and found them very helpful.
Various types of rocks have unique structural and physical properties that allow geologists to identify them. Using remote sensing equipment, those physical properties would register as a particular reading from the machine's output. Geologists would relate their findings to general characteristic analysis and determine the type of rock or mineral being examined.
Simply put. YES!
That is essentially what I have a degree in. I have a 3-year diploma in GIS as well as a uni-degree in Geography concentration in environment and resource assessment.
Trust me, there are AMPLE opportunities out there for you.
If you are focusing on Remote Sensing, I would advise getting background in either Foresty or Mineralology as those are the two burgeoning fields that are hiring the most. Your sex shouldn't be any hinderance and as long as you are not +50 year old, you should be okay.
I would suggest learning python and VB if you were to learn any programming languages though, those are the big GIS languages.
Hi a subject like remote viewing would get a better response from the Alternative category, maybe you should repost this question there.
Some people like the imagery from spy satellites. But I prefer the spectrally resolved visual and near-IR data from, uh… nevermind.

These are mostly sea based. Try them out.
hope they help
There are a few algorithms that you can use. You need to find the one that best suits you conditions and spectral values. Some GIS programs already have some algorithms for this purpose, but i don't know where you would get other algorithms from though other than the ones already in the GIS program.
I did something like that in university a few years ago and got a good image as a result, however, buggered if I can remember what algorithm I use.
Sorry
The spectral reflectance curve is the most accurate data that can be provided regarding a color's characteristics. However, a spectral reflectance curve is a graph of 31 readings taken at 10 nanometer increments along the electromagnetic spectrum from 400 to 700 nanometers.
The EPA also provides a spatial display and data query software package known as BASINS which operates within the ArcView Geographic Information System (GIS) environment. The database is indexed according to the US Geological Survey Hydrologic Unit (HU) code. The BASINS software also links to the EPA hydrologic model HSPF and the stream flow water quality model Qual2E which are also calibrated by USGS HU. The entire USGS database of water quality stream stations in the US is also available and can be queried. BASINS allows the database to be queried directly or according to statistical characterization, i.e., data quantiles, observations above threshold, etc. The current attainment status of each HU in terms of quantiles above threshold has been determined by EPA and the results can be displayed through BASINS.
