not that i'm ease one of the most the corny capital c. never out
00:00:05
however until recently we had an incomplete overview of it i factual history
00:00:11
today one billion points acquired with high precision laser technology enable
00:00:17
us to retrace the complete history of this masterpiece
00:00:21
the the that is what they call up when flopped a set of the points
00:00:26
that represents a new source of of information in natural resource management smart
00:00:33
cities architecture if basically this data is useful whatever we have three d. objects
00:00:39
and at the same time it is quite quite easy to obtain
00:00:43
however to be able to take advantage of this they that we face to major challenges
00:00:51
we had to be able to store massive amounts of data and we need to to set it efficiently
00:00:57
for instance and they're yeah size of netherlands produces more than six hundred billion points with
00:01:03
the current that not much and of course this will increase in the future
00:01:08
now imagine the size of the that that you have to store and
00:01:13
process uh if we track this area over a period of time
00:01:17
for instance we want to discover what has changed in this area and how it has changed
00:01:23
uh there for storing such massive amounts of the that is challenging
00:01:28
how that are at the same time it opens up possibilities for inside the thing everything before
00:01:35
to tackle the challenges we uh designed and developed a research project
00:01:41
that in i think behind a popular database management system
00:01:46
we base our solution on to love but it concepts
00:01:50
you sure it is compression and space between cracks
00:01:54
it sure does compression thing if it'd be used as storage requirements by mapping
00:02:00
one caught or three d. domain the least of continues integer about use
00:02:06
while spade thinning curve it's and it allows to efficiently
00:02:11
organised and search point about data by might be neat to one dimensional dummy
00:02:19
we can do in a holistic design uh by constructing if they
00:02:24
think of order over compressed active usually introduce dictionary space
00:02:29
and if enable us to achieve both high performance and low storage requirements
00:02:35
um with our prototype we it uses storage requirements by up to
00:02:40
sixty percent compared to the state of the art approaches
00:02:44
and at the same time we improve the quality performance by up to
