Remote Sensing: ERDAS Imagine

Lab 5a objectives were to calculate wavelength, energy of EMR, and frequency.  The other part of the lab was to learn how to use ERDAS Imagine and view the data with the Viewer.  The final part of the lab was to take subset data and prepare a map.

The first part of the lab compared the relationship between wavelength and frequency.  The calculation compared wavelength to energy.

Once in ERDAS Image, I played around with various tools such as zoom and pan.  It was also important to go through the different options for the raster after adding it to the table of contents.  After adjusting options. added a Viewer #2.  After having the image of Washington, I adjusted the color bands to show the forest land.

Another tool I learned was adding a column to an attribute table.  This helped show the power of ERDAS Image and exporting to ArcMap.  Using the Inquire Box tool from the Home tab allowed me to select an area of the Washington State image and then subset created the smaller image.  Exporting this into ArcMap allowed me to change the symbology to show the different classes and then prepare a map.
