Automating the TERASCAN Process
Abstract
Automating the TERASCAN Process
Since the establishment of the Center Of Excellence and Remote Sensing Education and Research (CERSER), it has remotely sensed Advanced Very High Resolution Radiometer (AVHRR) and Sea Wide Field-of-View Sensor (SeaWIFS) data, and it has been processed, annotated, and converted into .tiff files manually by using a series of Terascan and LINUX commands. This process is time-consuming and requires a person to physically be at the Terascan machine.
The objective of the 2005-2006 Remote Sensing Team will be to automate the process of creating AVHRR images. This will be accomplished by first creating a TeraScan dataset that delimits a geographical area of the Earth and specifies a map projection and pixel resolution, also known as a ‘master’, to the areas of North Carolina and Virginia. In addition, a script will be created which will process raw AVHRR data from the passdisk using the ‘master’. Next, a coastal boundary, gridlines, wedge, and a legend will be overlayed on the processed image. The image will then be converted into a .tiff file. Once images have been processed and converted into a picture, they will be sent to the server, which automates the process and eliminates the need for the individual to manually process the data
