by the contracting company. It is planned that KMS will focus
on image radiometry and image processing in the future,
because we see this as a procure of high importance on the final
image results.
The data volume has been seen to explode, when going into
digital image collection. This will to some extend be solved
when software in time are ready to handle 4-channel images.
But even with 4-channel images, it must be evident that
working with aerial images, data volumes are and will still be
huge.
Regarding image metadata, this is a topic that has been focused
on by KMS in resent years. This was caused by a potential risk,
to end op having an image-bank containing images with no
metadata (time, location etc.). We experienced that it was not
an easy job to secure that metadata are available an in sufficient
quality, as some companies don’t focus enough on this topic
Images and end-products as orthophotoes and derived maps
derived from digital cameras data, are found to be of generally
high quality. Even though, images still end up showing some
unexpected errors.
