Lab 4
Goal and Background The objective of Lab 4 was to introduce students to numerous functions and processes in Erdas Imagine that will build up skills in image processing. The particular processes in Lab 4 include: two methods of delineating a study area from a satellite image, optimizing spatial resolution through pan-sharpening, a radiometric enhancement technique, linking a satellite image to Google Earth, resampling methods, mosaicking images, and binary change detection through simple graphical modeling. Subsequently, students are better prepared for image processing, enhancement, and interpretation with experience with these techniques and methods. Methods The first skill introduced was subsetting images in order to focus on an area of interest. One method was using an Inquire Box - a simple, but limiting method because areas of interest are often not simple square or rectangle. Using an image of Eau Claire ...
