Tips<br />
Much <strong>of</strong> what <strong>is</strong> required here you have done before so you should try to remember how to do th<strong>is</strong><br />
again.<br />
1. To convert the DN values to at-satellite radiance, you first need to construct a formula <strong>of</strong> the<br />
type l<strong>is</strong>ted in equation (1). You can then apply th<strong>is</strong> formula using either band math or the<br />
gain/<strong>of</strong>fset preprocessing function. [To do a log use the alog function and be sure to use your parentheses<br />
correctly].<br />
2. You can use ROI tool to determine both the at-satellite radiance and at-satellite temperatures<br />
for the different surface features.<br />
3. You can use Basic Tools Stat<strong>is</strong>tics Compute Stat<strong>is</strong>tics to compute the stat<strong>is</strong>tics for an<br />
image.<br />
4. To do pseudocolor mapping <strong>of</strong> temperature on the Image menu select Tools Color<br />
Mapping ENVI Color Tables to set a pseudo-color for d<strong>is</strong>playing a temperature image.<br />
Select an appropriate color table that makes sense to correctly d<strong>is</strong>play temperatures.<br />
5. To smooth the temperature image suing a low-pass filter, which can be found in Filter <br />
Convolutions and morphology on the ENVI main menu bar. You should select the<br />
Convolutions and Morphology Tool window, and use a Low Pass with a 3×3 Kernel Size. Click<br />
Quick Apply; select the appropriate input band Notice that the temperature image <strong>is</strong> smoothed.<br />
Make a hard copy <strong>of</strong> th<strong>is</strong> image and include it in your lab report.<br />
