Scenes were picked that were from 2016 and had a cloud cover percentage less than 10%. One Scene was used from 2015 due to no suitable scenes being available for 2016. Data Development: This TIFF image was created using ArcGIS. To create the color infrared composite each individual scene needs have the red, green, and near infrared bands together. Using Landsat 8 data means that near infrared is band 5, red is band 4, and green is band 3. When setting up the individual scene composites the no data value is set to 0. This gets ride of the black square that surrounds the TIF. Finally when the individual scenes are completed they are ready to be mosaicked. The final mosaic used a blend mosaic type. The blend type decides the output cell based on a horizontally weighted calculation of the values from the overlapping cells. This method helps clean up the output image. When the final mosaic is complete the last step was to create pyramids and calculate statistics.
