6. What is the preparation, indexing and cataloging
phase?
This phase will require a large amount of time but will not incur
huge costs to the client. During this phase, the acquired data will
be verified for a variety of things, organized, grouped, prepped
for indexing and cataloguing, and lastly placed on one of our
systems for the indexing and cataloguing stage. At this point, all
issues and priorities must be known or additional time and cost
will be incurred later.
The indexing and cataloging of an image is an intensive
computer process. It requires one computer system to be
dedicated full time during this process. This process can take as
little as 8 hours or it can take as much as 3 days. Please note
that this time is not determined by an individual, it is determined
by the number of files, size of the hard drive, and the other
issues affecting the acquisition phase. As a general rule, the
process takes approximately 1.5 to 2.5 hours per 1 GB of data.
(A 40GB hard drive can take between 60 and 100 hours to index
and catalogue the image.)
Now the good news, the majority of the time involved in the
process is not billed to you, the client. The client will be billed for
setup and monitoring for the process; a few hours per image.
