Image to Map Rectification

The process of rectifying an image to a maps coordinate system has its advantage and disadvantages. The advantages after matching ground control points in the mapping system to points in the image is the elimination of errors in the data in a GIS. After the rectification process, cultural features are now assigned with accurate coordinates.The disadvantages in the process occur when the images lacks identifiable features making it difficult to locate a ground control point. Also, user error when placing ground control points can distort the image and make a mess out of the whole process.

Thermal Infrared

Roads-appear lighter due to the materials higher heat capacity
Natural and Man Made Vegetation- the vegetation's heat absorption depends on the moisture content and whether or not the vegetaion has been watered or if rainfall activity was present.
Sidewalks and Patios: Heat capacity and color in the image is similar to Roads.
Storage Sheds in back yards: darker color is indicative of a low heat absorption rate.
Automobiles: Car materials similar to shed except the hot spots over the running/previously running engines.
Bright spots on many of the roof tops- kitchen exhaust vents will appear lighter on roof due to the heat rising out of it.

Module 2

First difference I noticed was the color. The color for the panchromatic image uses a single band whereas the MSS uses 3 bands (4,3,2) Also, when comparing both images, I noticed that the resolution for the panchromatic was a lot clearer and not as fuzzy as the MSS image.

Projected Aerial Photograph

A common problem with color infrared(CIR) aerial photography would be identification of the features, especially if you are a newbie like me. CIR photography also makes it difficult to interpret the natural color and the depth of the features and objects.

offshore wind mill site

Norton Shores Offshore Wind FarmNorton Shores offfshore wind farm is located approx. 15 miles off the shore. This location receives an avg wind sped of 12 miles/ hr. Noise and shadow flicker will not be of a concern to residents since its 15 miles offshore. This location does not have any major shipping routes. I do not think migratory birds will be a huge issue. The east side of lake michigan does not have major routes when it comes to migratory birds,
