ABSTRACT
Automated Approach of Cataloguing TeraScan
Images utilizing Exchangeable
Image File Format (EXIF) Data
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 http://cerser.ecsu.edu.
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.
The conversion of the tiff
file to its various resolutions
and the entry of data into
the tracking database are currently
done manually by the CERSER
webmaster. The amount of time
to enter one image into the
system is approximately ten
minutes. The process is also
limited by the requirement
that the webmaster be located
at one computer terminal located
on the campus to perform these
tasks.
The goal of the 2005 ONR Multimedia
Team (MMT) is to automate this
process utilizing data captured
from the tiff files Exchangeable
Image File Format (EXIF) data.
This data contains the capture
time and date along with file
resolution and file size. Utilizing
this information will allow
various scripts to be written
eliminating the necessity for
the manual conversions and
data input to be made resulting
in a more up to date and accurate
archiving system of the images.
Various methods and languages
will be utilized including
Java, JavaScript, and Adobe
Photoshop Action Scripts to
complete this process. |
