History

The pattern of outward growth from the Merrimack river can be shown incredibly well with the aid of remotely sensed data. Using different bands of landsat data, I have created a number of images to show the trend of urbanization growing out from the Merrimack river. All have been pan-sharpened as well to get the best detail of each city.

True Color The Merrimack Valley region in true color.	Near Infrared This image shows the track of the river quite well.	False Color Infrared This image shows all of the cities in the Merrimack valley, starting with Newburyport, Haverhill, Lawrence, Lowell, Nashua, Manchester, and Concord.
Bands 1, 2, and 4 Another view of the Merrimack Valley, better showing the sprawl of each city.	Bands 6, 4, and 2 This is the best image for displaying the total area of urban land cover in the Merrimack Valley.	Classified A classified image of the valley, where urban is represented by gray, and non-urban by green. Note how much is based around the Merrimack River.
