Land-use/land-cover Classification of a Section of Baltimore, MD using Landsat TM Image of 2010 Paper details: please, read the article to be used and write what you understand page 2 and 3 are instructions the one that called project 1 is what i did on lab for this project so just read the the article how to do the lab on write about. My bands are 3 and 5 please mention that on the essay. Also, i would like to get 2 sources Remote Sensing (RS) Classification Procedures using the Environment for Visualizing Images (ENVI) for Introduction to Geospatial Technologies for Civil Engineering (CEGR 110) Course. By Dr. Frederick K. Wilson, Morgan State University, Baltimore, MD, USA. RS Software: EVNVI Classic Launch ENVI Classic by going to “All Programs” Click/Select “ENVI 5.0” and Click on “ENVI-32 bit” and double click on “ENVI Classic”. The Main Menu of ENVI is launched. Click on “File” and on the drop-down menu, select “Open Image File” Navigate to the Folder where the Landsat Image (LT50150332010263EDC00) is stored and select the Image File (do not select the Header File); click “Open”. The “Available Bands List” window opens, displaying all the 7 Landsat Bands. 1. Displaying the image in Real Color Composite Display: i. Click on the “RGB Color” Radio Button ii. Click on the “R” Radio Button iii. Select Bands 7, 4, & 2 iv. Click “Load RGB 2. Classifying the image: i. Go to the ENVI Main Menu and select “Classification”. ii. Click “Unsupervised” and go over to “IsoData” and double click on it. iii. The “Classification Input File” window opens with the Landsat image “LT5_2010_263” . iv. Click on “Spectral Subset” v. Select the Landsat bands assigned to you. To select more than 1 band, please click on the first band, press the “Ctrl” key and then click on the rest of the bands that were assigned to you. Click “OK” on the “File Spectral Subset” window and again click “OK” on the “Classification Input File” window. vi. The “ISODATA Parameters” window opens. Input the criteria assigned. vii. Click on “Choose” on the “Enter Output Filename” section. Type the Output name or navigate to the drive or folder and type the name of your file. The classified image is saved and at the same time displayed in the “Available Bands List”. Select the classified image – ISODATA (LT5_2010_263). Click on the “Gray Scale” Radio button, click on “New Display”, and click on “Load Band”. viii. The classified image (shown above), is color coded by the System. Such as Class 1 – Red, Class 2 – Green, Class 3 – Blue, Class 4 – Yellow, Class 5 – Cyan, Class 6 – Magenta, and Class 7 – Maroon. However, these colors (for each of the Classes) can be changed using Real Color Composite image as a guide. ix. 3. Changing the colors of the Classified Image to resemble the Real Color Composite display image: i. Link the two (2) displays – Display 1 and Display 2 by clicking on “Tools”, selecting “Link Displays”. ii. The “Link Displays” window opens. Select “Yes” on Display 1 and 2. Click on “OK”. iii. Now that the two Displays have been dynamically linked, the Classified Classes can be determined by clicking on “Tools” on the classified image window and selecting “Color Mapping”, and then clicking on “Class Color Mapping”. iv. The “Class Color Mapping” window opens showing all the different classes obtained during the Classification Process. In this Case it showed 7 Classes. (Currently, 7 classes and the Unclassified is shown) v. Click on “Class 1” and determine its color (Red). Now move the “Red Box” in the Classified Image window and drop it over an area that has this color (Red) and observe the “Image Window” or “Zoom Window”. Put the “Cross Hair” over the color (Red) and press the Right Mouse. Observe the color of the feature as it is displayed in Real Color Composite. Note the color of the feature in the Color Composite Display, since this is the feature that is colored “Red” in the Classified Image. In this Case, Class 1(colored red) is Water Bodies. Repeat this process for all the other Classes. vi. To change the colors, click on the class on the “Class Color mapping” window, select “Color”, move over to “Colors 1-20” and select “Blue”. In this Case the Red Box is over the Loch Raven Reservoir which is a water body. vii. Once the Classified Image has been color coded, it can be saved to be used as Figure in the Report; the Real Color Composite image can also be saved to be used as figure in the Report.
