Final Maps and Analysis

Two Views of Washington D.C.
For the map analysis I composed two views of the city of Washington D.C.

Original Image

As you can see, details in natural elements such ad water and vegetation have been more enhanced and easier to differentiate from build up regions, like roads and buildings.

For my next view I added a pseudocolour layer to all seven bands to compare which band applying this view to would help with visual analysis of the satellite image and what features were better highlighted as a result. 

As you can tell from each addition of  pseudcolour layer, it is not always as clear or useful in every band and some bands can offer more information that others in terms of what can actually me analysed on the ground, especially if enhancements and classifications were performed on these images. But the addition of all layers allow us to see the multiple aspects of each layer and let us determine what features are on the ground in terms of water, or vegetation in developed cities like Washington DC.

Two Views of Banff National Park from the view of Canmore

For these views I used zoom features as well as enhancement features.

For the zoom features I used an overview map and a zoomed image. The zoomed image was used to illustrate the lack of detail in TM images in terms of analyzing small pockets of an image like Canmore. The zoomed image was as close as I could get to viewing the actual city before the image became too pixelated. The overview map was used to illustrate the idea that TM images can be used for large areas like the region of Banff that is featured in the image and to zoom in to specific attributes like lakes and large vegetated regions for analysis in general regions. In terms of detailed analysis, it would be very difficult with these types of TM images. 

For the next view I wanted to compare images after they had been enhanced to determine whether certain enhancements are more suitable for certain analysis.

This is a linear enhancement of the region.

Not a great choice of enhancement though, as it made the image extremely dark and not easier to interpret the data.

Comparing the Linear enhancement with a Root Enhancement.

This enhancement would benefit interpretation of the satellite data especially because I am looking at finding details of the city of Canmore and the better I can see detail the more it will benefit my interpretation.
