What We Do

This site is about "remote sensing" and how remote sensing can be used to solve everyday problems. Our emphasis here is on satellite remote sensing, though we are not limited to just satellite data or expertise. For example, many of the techniques we use can be applied to aerial or ground-based remote sensing, as well. This site is also a major arm of CARSAME (Center for Applied Remote Sensing in Agriculture, Meteorology, and Environment), whose purpose is to be a regional resource center for both remote sensing data and expertise to use that data.

What is Remote Sensing?

Remote sensing is the process of observing an object (or scene) from some standoff distance. In other words, we watch what is happening from afar. The "eyes" that we use are a variety of electronic sensors which measure electromagnetic radiation such as visible light; though, we can also see "radio" waves and "heat" waves with our sensors. The platforms, where these sensors are mounted, are a variety of earth-orbiting satellites.


Several words of caution need to be presented to the users of these web pages. First, we are only in the earliest stages of setting up an operational applications center. Because of this, this page will change often and dramatically as we receive comments from our colleagues and our users. Our imagery is currently at an unrefined state -- it still requires careful processing to account for the following:

         1. atmospheric correction
         2. cloud cover

Until these steps have been instituted, so that the data can be processed in an automatic manner, the images that we present here are useful mainly in a qualitative sense. Upon completion of these basic steps, the data will have meaning quantitatively and we will, at that time, provide for download of data which is of scientific use (i.e.; in standard remote sensing/image processing formats). Until then, only the images that you see are available (as you would save any Web Page image).

In time, we will also go back to our archive of data and reprocess it so that it will be of use as well. You will also notice, in some cases, that there appears to be data missing from our region; this is because many of the satellite passes do not acquire data over the whole region in one pass. Instead, it may take two or three passes to acquire the whole region. At the present, we will only present those passes which cover a major portion of the scene and we will not attempt to patch together passes to create a whole - - this too will be left for a later date.

As you can see, we have much to accomplish. We ask your patience in this endeavor. And, we ask for your comments!
