Lab06- Image Enhancement

GIS 4035

In this weeks lab we worked more with the ERDAS program as well as ArcMap.  With the government shutdown we were unable to get into the USGS website to download the Landsat 7 images, but our instructors were kind enough to provide the data to us.  With the data downloaded and extracted we began to perform spatial enhancements.  We utilized Fourier Transformation function as well as Basic Filters found in both ERDAS and ArcMap. 

I felt most of this lab dealt with Convolution Filtering found in the ERDAS program, and we were able to utilize different Kernel settings to see a multitude of outputs based off these settings.  

Finally I was tasked with modifying an image to generate an image that reduced the Scan line corrector failure lines so that they were less  noticeable, but the image still retained enough detail to let the viewer see the obscured image.  This image is shown in the map above.  As is the description of the steps taken to clear up the image as much as possible.
