Automated Approach of Cataloguing TeraScan Images Utilizing Active Server Pages ONR Multimedia

AUTOMATED APPROACH OF CATALOGUING TERASCAN IMAGES UTILIZING ACTIVE SERVER PAGES Abstract The Center of Excellence in Remote Sensing Education and Research (CERSER) on the campus of Elizabeth City State University is currently tasked with the responsibility of receiving remotely sensed Advanced Very High Resolution Radiometer (AVHRR) and Sea Wide Field-of-View Sensor (SeaWiFS) data for research projects year round. This data is collected, processed, annotated, and transformed into images in the Tagged Image File Format (tiff). These tiff images are then uploaded to the CERSER archive library server located at Once uploaded, they are converted into various resolutions and their information is added to a tracking database maintained with Microsoft Access software. This database provides a searchable means for retrieving satellite image data through various parameters.

AUTOMATED APPROACH OF CATALOGUING TERASCAN IMAGES UTILIZING ACTIVE SERVER PAGES Abstract (cont) The automatic conversion of the original tiff file to various Joint Photographic Experts Group (jpeg) format sizes and the entry of information into the tracking database were completed during this project. Active Server Pages were developed utilizing Visual Basic Scripting, Structured Query Language, and Command Line instructions to the software package ImageMagick™ to complete the tasks. The final file developed was added as a scheduled task to be implemented at a certain time each day on the CERSER platform. This file inventories the “original” folder located on the CERSER server to determine if any files have been uploaded and then processes those that have.
