<div dir="ltr"><div><div><div>Thank you Tereza for your quick reply,<br><br></div>I would be really interested in having a look in your presentation paper when it will be available. In my opinion, your work is on a very critical subject for those who are editing and creating official data. For instance, when administrative limits like cities boundaries are evolving or been
adjusted to a new cadastral plan (what they do on a monthly basis in Canada), all subdivisions
have to evolve in consequences to follow the new limits. Doing it manually takes more than a month for our little team!!! Actually, it seems that only ESRI can efficiently manage vector conflation, and their vertex snapper tool is probably the best editing tool so far. For our public organization we are a bit chained (sometimes against our true will) to this kind of proprietary and expensive solution. I encourage you to pursue your work in this way if you want to. Im sure many many people around the world would be interested in such an open-source tool.<br>

the development of QGIS conflation plugin was the aim of my bachelor<br>
thesis. But it is not ready to use now and this depends on my time<br>
possibilities, but I would like to work on it a little bit during<br>
august. This project consists of library with some algorithms and QGIS<br>
plugin using that library. And I was thinking about its integration to<br>
GRASS, too. I don't have materials with me now, but I could provide my<br>
presentation from Geoinformatics Conference [1] next week. The code<br>
and documentation are not published yet but you could take a look at<br>
my bachelor thesis [2] - thesis is unfortunately in czech, but code<br>
and docs are in english. This plugin might by useful in some<br>
situations, but it is not ready for bigger projects. I think that it<br>
can not replace ESRI topology tool now.<br>
<br>
