In this week's lab, our main focus was classifying and applying raster imagery to a real world scenario. We will analyze this imagery to identify Mayan pyramids in Mexico.
Below is my map output from this week's lab assignment.
The Landsat raster data was downloaded from USGS Earth Explorer and covers a portion of the Rio Azul National Park in Mexico. The downloaded data came with 9 different (raster) bands, for this lab we worked with Bands 1, 2, 3, 4, and 8.
Band 1 = Blue, Band 2 = Green, Band 3 = Red, Band 4 = Infrared, Band 8 = Panchromatic
Band 8 is panchromatic and has the highest resolution (at 15 m). It appears in black, white, and grey tones. Natural Color is the combination of the Bands 1, 2, and 3. They were combined using the Composite Bands tool in the Image Analysis window of ArcMap. The result is a natural looking color image. False Color is the combination of the Bands 2, 3, and 4, also using the Composite Bands tool. In false color, vegetation appears red because it readily reflects infrared energy.
