Talking about 3D used to sound cool. Used to. But for real GIS use, we really need more than just playing with a globe. 3D in GIS becomes cool as soon as we have the ability to deal with full 3D spatial analysis. Just as we already have in 2D, we need functions like intersection, buffer, triangulation and more ... The GEOS library provides us 2D topological processing for years. The CGAL library could now also provide us some interesting additional 3D topological functions. As CGAL is not fully designed for GIS data models, we provide a library inbetween called SFCGAL, in charge of providing a Simple Feature API on top of CGAL. PostGIS 2.1 now allows to link PostGIS and (SF)CGAL, and already provides several exciting 3D functions (and more and more to come). This thrilling talk about PostGIS 3D will therefore focus on : - What kind of project / application needs 3D GIS analysis ? - What can we do right now with PostGIS 2.1 and (SF)CGAL ? - What we will be able to do soon with PostGIS 3D ? - Some tools used to view and manipulate 3D data (QGIS / WebGL based)

and so on and so I'm in this for the addition of some of the history of the world in the hope that the tree is the solution so the
solution for site that it is on Europe and on the idea is to be able to of solution last sold display including and being of people at the University of management to the future of the city so the tree of filling up the a road to treatment from right now we
begin to the with trading the soul of the party understated into the US and the UK which is being fought by the end of the century the to create but we will use the meeting to play with but history in the 2 days and then we saw the 1st implementation of this to the 0 0 and at this point time we will write a boat to store and to include tree code to try saw something like seeing and productive faced directly into the side is we have the ability to to to so to the head when the related to the treaty that the 2 of and has a new group seeming to produce presentation you could be in with this kind of future but it to those who will begin into a single like the journey the code solution for free on the internet on their way to the trauma of the some some of the wittiest and listen to the wrong you wrote as 1st because we provide some staff the for pretty so it's not only starring in manipulation each specimen used to I'm so although the abuses of the of the user assiduous to move the way is to be and that it is competition but there is something more than just think is is that the key to link the 2 with a single and the with the single is a when the intruding manipulation literate and we need to make the link with something in the code and the single as the legacy of the future of the world he knows the future for the result is that a lot of it was to have something like a banking and also something like other commercial because in the US early is simple future and in singles literally focused on the tree it said so to kind of different from and there is a need to do something in the middle to from the convention sir
we has ability to to link the 2 areas where he is the function of cigarette but the of this as a moment we provide only a few from show a new friend year
to see where some of the weaker
than the right now go into the hands of the Department of some from show in is to and some of them are really really interesting and the background of something extra the intersection something like this is true and also stressed that it and its rivals are interesting because they are less provide this kind of future in those days we also provide
and so that the names of those who on the soaring issued but some sort of the beginning the crew of the tree and lady even treaty and was tree triangulation from this
distressed that it on each of the 24 to of bidding you could get out of its footing and then is a book but there is about as good a time was a bidding displaying and we exhausted but it and you could contract issue went from the roof of the building and at least believing the super rich for me and
we provide them with the city and some functions as the only way out of the woods yet so I think that to be be just that trading effort in the stands to the distance discussion with an anti American messages that we also provide true to get at them and you have of which is to to say
OK what his men and women G where and when to use the cameras at the city and has a good line from shunned by the ability to chose to say OK Holland is designed to do so the public dynamic related to
a session that we the press as the into the that some of this is of the so are it's supposed to be either a cure the and was abused as a due to failed to beat the best of the internet to cheque that the real thing and the crash and was the lowest in the between trade but it's a fact its yet of the New Labour elite so we have not yet but user commuting to say OK educated in the exact cucumber duration on exhibited just days and at this point he doesn't talk and expected to sell up to a week earlier waiting for 1 of those people who use it and to say OK open its case because of found
that the difference is the right now if we go down to the gym and the city would be used only for the tree offensive are quite the same way to me but the point is not that time in the studio because I think we did in the lavatory procedures that night and that is not evident until so even if we had a great simulating the from the sea in the game because we are not treating and on the other hand and you could be competition that it said could take the and so on but the means to do that is assessed by just the treaty back to that day I'm not sure about the past and that is a show that will now to will stand out as a talent to of rooted in the largest city in the Bay of rooted in insure weeks after months of waiting to trace so I'm we are not going to do is understand that they should to be sure that there we ought to do not would be compared with the new committing by some of the strongest in the city and in the eyes but at this point but it fares are closing injury that we are only at the because the something walking the area but the show is something we are missing is the key to run bringing tree and to see what we ought to do it did so at this point which to to me to enter a new proliferated who what could to to display and sold out of the area and there was a need to improve in Asia to display producing the was named in which is what we do need to see the great to be good to see something Tree some sort of back but was on the bench at the back of the queue with his family in the UK the US and the while and the aim is beginning to make the link between the MMR because and the trees sir issues says something that we could do was disturbed by its 3rd asylum was was from the mid though that we did the match at the beginning of of the week was along with the fans and for the so
that is an example in which is a huge into the which is on the
notion of a strict because he could but be on the of the
opening of with a trading around ring why was same not
and that the world was shooting was a
meeting looming also includes a trip the IRA and displays and you could see was that it was the to to changes in
the UK and to submit the addition of a
new government we want to work add the new to the UK but the footprint so I'm on the same kind of set up of into
the end of the stadium on the true
during at this point it's only to me but that was it to be a taste of the and that's
becoming more interesting because as the to to extract as that 2 security at the beginning of a the threat to believe in but which is now about to extract that of the 2 them we is the name of the game
and you create a new EU geometry energy to in the and to display into a team that mapping trade and and the and it's not really that the makers of the
to found that are out there and is really a moment was so are able to see including the
idea that this is the end of the sort we need to win do to compute built the evolution of the human being and we let do because we don't operating as version of the but it stressed so we as the key to compute restaurant and that the really into securities trading is these and to
translate into being to write about computer that and the road to war on the basis
of the motion of a and AS
moving into a new and intriguing and if we focus on the basis for the movie which is an area of the city says that it is providing a further 1
nutritional solo saliva degradation
of some political so that his family would be sure to come under the overall between the 2nd and
listen to the tree and a prisoner of the goods in the UK that of those fans on the system in order to do that said that the 2 0 2 2 wait 2 long in and now we begin to
something in the air to begin ready to play but it is true that that to the
friends and treaty and and the disease is so including those of early to related to on that the and company in the other
room and ducks in December and if I focused on
display as well as to the true in the UK so the question is if we need to extend for being sacked by the fact that the programs that and only make returns from the UK and was extrusion were on the beach trucks and media into the and trading letting Irish I'm forbidden said and the next
which ended only is any sense that the 2 banks leading to to floating was of course the in the sector including the launch of a new quality asking is pretty and fiction between these 2 clubs and the FA will not and I don't from the and the and the Oscar and is treated as a child and she has created a new the world was so the duration of the said the talks sick also something like that is can of basic to the from the Treecode and section and at the end of we have to take with a result so did not we have to go and we just have to refurbish display with team and into the with of the tree and the and the and the as a room so you go on the trip is section As a new Williams and the
problem with just from some kind of training
handling trade is to say that and the dimensions and extreme and so we can use the data to display Simics information about the event that the so in and that there and the the key to make station and the City 2 to
come from the back so the use of has about to around the house all day and night and make out there in the city if a banque is a by the user of major available sir
if you look at them once again to you should to we go on the cement of the as a cigarette as the new leader of the banking system be used to be that the deal was to remain at the heart of the dispute over the will of the views of some of the weapons and the and the gym as well as far as well as well as needed to to continue to to improve again and his friends are and we don't have to to do that mesh to them because they are quite true by the state when the and the NHS you could
find that each of the 1st time just some of the best of the rest of the year and a half inches the police have yet to use the latest figures show that and although and changes we use of the 1st rank of action sir on which is the next that we have been in the next that it is and that is to increase the and and and the number function and with to something extra unit trillion relates Tree simplified the grant is to improve and and and again as running the of the as something of a week and a bit to beautified again the tree during the day and was in to do players without the and so that we have a huge this treaty arguing but we don't want to express solution based on the board yet if
you want to play it was a presentation earlier the right now on all night and you could find the right shaped by quantity to of the to just was only 2 so she went to do it but he was still the best but it was be and as you have to prevent them because of the nature of in the beginning of the week we also I've who from the moment individual books of the world so it's something of one's we can provide it has 6 at the debate which the but it was to go to to you could buy it and it you rooms the centre would be built or you may have to follow the
the the great but to fund this fraternizer it is only when the time limit on the amount taking to the political and social security at and is in the shadow of the communication is a lady to adding that trading in the UK because of the wrong way as the rest and that when I 82 to and and as well as some saying something that is a reasonable to unify so the future rescue user exhausted among Jim in the same kind of thing doesn't right we are not the only 1 of the books was so that the Fed was some kind of litigation with the kind of world we have to move to the stand we would want to do the job between in but base every but which yet each of the 3 much of the old so was
the fence in the ability to suppress
proof on a regional basis the Labour leader of the University and was a member company so because there are several University said that there was still with a 2 2 draw inside the singer who is something of a winning side and there was some of the some of the different instead to go out in the 1st of many of the men
tried to do banking was not too difficult to the connexion between the president itself from the rest of the world and is a senior trading or so small addicted to coalition and to test the of Israel have done consuming for children to be sure that between between or and on all nicely and their the email was a a we case almost today with but but the the instead saw if you look at home in the UK that we could be in the on of the of his case and was to be index because of what we have to do is relax and he is a strong of Trigger objects that by the end of the month was attributed to the current or used close we just before the is to produce plays without TradIndex is meaningful for from all on a city for them the origin and it Quinn could be that he was to there is also a tree and a tradition index available so she wanted to ever if you nemo questions plenty of time but it was kind of life it is guilty of un global history the and and at the same time of it where in all night on the roof on and on is arrested that could be worrying could be quite begins UK his big city to and and the and the presence of this case all the way that we would say it was quite common that it's not dedicated treaty on tritium something like that to play with a with just needed acquitted centre and the Tree acceleration and the and the City and the other was close we also opposed to tour going along was new Citigroup the of a big city in the world by 3 or 4 4 2 and and is not easy and it is that the IRA use case so we would not try and so that latest what the for a while and yet capable of this area at this point that we are only at the last by playing career airline transparency and caught at this point and to to go to live
it the December the and order
is quite music for some you have to to feel that following systems and but in between the and that become brand new of and and is now and the only 1 that can be heard transparency and texture sold it a striker but that my see here on the street the of light for kick out of it in fact on the human body should plays a lecture you would see that we to win the and the and and the and the 2 of them another is only able to to fix city during the and the or the project and they were to took some City heading into a in terms of the deal the soul's if you want to the as a way to use it to be and that the density of the inside of the latest and to begin to play with it was to this puts it it was is on the beach where the along with into 2 to disagreed to assess the and has a duty to get changes that and that was sold to a review by the sense of a cigarette is also out of has been educated and so it's a good way to use up a seems to do the Tree but of the 2 because of the meanwhile question that's not bad they showed
