and we of usually of the to move and you know we we we we we we really need to have a unique and very and we use the theory in the you know the the the the the around the around the world and the the and the money and so on and around the world in which we use in the the in the the the the and we we we we we we we we we we seem to be particularly in and around the world in the way that you would like to introduce you to the right of and I have the and you know we we we we we want to know I would like to know what a and a kind of a and a and a and B will be a thing and and the a and the meaning of the word in in the in the the the the the the the mind of my mind I'm the example of the kind of a summary of the data in the the the mind of the general a number of the in the in the
in the
eye of the the the the the the the the minus a half of the in the in the in the in the country CD-ROM and or we use the
things that might arise in the mind of my mind and my my here we have the the the only thing we really want to worry about in and we want to do and we have a lot of time and we
know that we we we we don't know the name of religion in the world we in the we have been we have a number of things we can around here in the in the in the in the in the and and we really we begin to move beyond the limits and the we we we we we we a a theory and we see the original and the and we believe and you really should be going through the use of the the U and the meaning of the and the parts
of the world and the removal of the history of of the user and the we don't really know what we were in a room and we the project so that you know the and and the in a and the the the the the the end of the day and the week and the week that we are in the area of the world around the in the
minds of the of the of the of my role we might be able to get a reduced the number of the and here we have a really good and I would like to know where my my my number of around the around the world and the
world around and around and around and around and around and around and around and around and around and around and around the world and we we tend to think in relation to the beginning of
the season in the form of a we remove the we would be interested in the in the in the in the in the in the in the in the in the in the history of the universe in which the the the the the the the the meaning of the word and we we we we have a we have a very good thing that a lot of the movement of the we and we we were we were interested in and we have to be here and we have a lot of people and we have around
the room and the number of
a
number of
different things the world and and we see that we have do in the form of rules and the and the and the and the period of the I would like to be there is a member of the newly the coming and we have been very recently been or in the and you can think of a number of the of the of the world the difference in the paintings and things like that of the system and the and the iteratively in the in the in the in the in the in the in the in the area we have to do the in the in the school and we end up with the in the in the in the in the in the end of the week
and the removal of the resulting in a change in the and here we can see that
we have and
1 of the the the the the the the the the the thing I think I can think of a better word in the in the world and the the the the end the the the time and a number of the of the of the of the of the of the of the of the of the of the of the of the week and the the and move around a little bit of a and a in
minus a half a mile radius
around
the time of the year the role of the state of the art and in the world the orientation of the moving in thing in the in the end in the the the the the the the the the the the area of the time I was going to be a part of the a and B and we have a lot of time and the area of the park in the in the in the models little wiggles and the you can think of the the knowledge that we have in a room in the rules will will will be released during the day and then you can go in and around and around and around and around and around and around and around during the during the period of time a and we we have a lot of in England in the in the use of the the the the the the the the the the the the the the the the the the the the the
the meaning and the use of the word in the query and you you you you you you you you you you you you could have a lot of learning rule in the theory of the universe and you can use the in the theory of the in the the the the the variance and you know the the the the the the the the the the you know the the the the area where the parents and the origin of the universe and the food and the belief in the beginning of the end of the wood and the you know the the the the the the the the thing that you would do you would you would you know the real you believe that you have the core of the things you only for the various you you you you you you you you you you you you you you you you you you you you you you you you get the you know or do you think you know

Abstract QGIS has seen a large amount of new functions and improvements during the last few years. And there is still more to come. This presentation shows the most recent changes and new functionalities in the codebase after version 2.8, both from a users and from a technical point of view: Curved geometries have long been a missed feature in FOSSGIS Desktop solutions, with such geometries usually ending up being segmented on import. A rewrite of the QGIS Geometry core now allows for native support of a number of curved geometry types, such as CircularString, CompoundCurve, CurvePolygon, etc., in addition to the traditionally supported Point, Line and Polygon geometries. As part of the redesign, proper support for M and Z coordinate values was also implemented for all supported types. Geometry errors can easily sneak into large datasets, either because of inexact data acquistion, but also due to gradual loss of precision when importing, exporting and converting the datasets to different formats. Manually detecting and fixing such issues can be very time consuming. To assist users confronted with such problems, the 'Geometry checker' has been developed. It provides the functionality to test a dataset for geometry and topology issues (such as duplicate nodes, overlaps, gaps, etc), presenting a list of detected faults. For each error type, the plugin offers one more more methods to automatically fix the issue. A third new function in the geometry domain is the snapper plugin. It allows to automatically align the boundaries of a layer to a background layer (e.g. align the parcel boundaries with a road background layer).
