In our first week we were asked to create a map using basic GIS tools and views. We added data in ArcMap and used tools to create a map showing countries by population:
In week 12 Georeferencing it was a bit challenging at first to create control points that overall had a low RMS reading. But after an hour or so practicing it got easier. The second raster image that I needed to fit to the first one did end up a bit warped in the end but I had to move on due to time issues. Images from my original data frame disappeared and due to time constraints I have to just create a map from what I had left.
This week we worked in Erdas Imagine to manipulate raster images. It was interesting learning the different applications you can use as opposed to Arc Mapping. I enjoyed being able to change the spectral bands in order to change the topographical features that you wanted to stand out.
Module 6 lab took us the through the use of many different types of filters in order for a user to sharpen or make prominent different features that may be contained in an image. The example below if the sharpened Fourier filter enhancement. It is not as clear as I would like it to have been but this filter is going to take a lot of practice to use effectively.
