8.
Satellite Receiver• Installed on Everett Tower2004.• Uses Terascan Software onReceiver in Rood Hall• Provides information forhydrolic, oceanographic,and meteorological studies• Inoperational since 2008.

9.
Satellites• Noaa 15 - 19• Advanced Very HighResolution Radiometer(AVHRR)• Advanced MicrowaveSounding Unit-A (AMSU-A)• Microwave HumiditySounder (MHS)

10.
Terascan• Proprietary Seaspace Software• Used for downloading raw data from polarorbiting satellites.• Converts raw data to various imageformats.

11.
Problems• Reciever wasnt communicating withsatellites• Outdated software and hardware• Poor documentation• Licensing Problems

12.
Outdated Hardware and Software• Updated to Terascan 4.0• Upgraded hardware• Installed CentOS

13.
Poor Documentation/Licensing• Contacted Seaspace• Renewed License

Testing Image Accuracy & Aquisition• View images as they are aquired• Verify images against images that areknown to be accurate• Set up a log that logs when images arebeing downloaded

44.
Testing Image Database Insertion• Automate encoding into GEOTIFF format• Verify images visually• Log automated transfer of encoded imagesto database drive• Log automated insertion into database• Log removal of images on original box tokeep clutter down

45.
Automated Transfer of Files

46.
Automated Insertion Into Database

47.
Testing Web Frontend• Group testing of featureso Attempt to break Everything we have implemented• Client testing of featureso Make sure they dont break anything accidentally• Ensuring security of database connection

48.
Testing Robustness of Backend• Multiple connections• Query for non-existing image• Attempt to access restricted information onthe server

49.
Summary• Automates image aquisition, processing,and insertion into database• The backend will automatically makedatabase images accessible from the webfrontend• The web frontend will overlay the imageson a (google) map and allow meta-data tobe viewed
