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. |
