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.
