Good day,
I am new to this list, and I hope to get information (papers, powerpoint presentation, etc) about an upcoming GRASS-QGIS plugin for vector conflation.
I was searching on the net on this topic and someone fowarded me to Tereza Fiedlerová works on this topic disscust in the GRASS Community Sprint Prague 2013 (http://grasswiki.osgeo.org/wiki/Talk%3aGRASS_Community_Sprint_Prague_2013#Tereza_Fiedlerov.C3.A1)
I’d like to look at, if its possible, papers, pwpt, etc, on this upcoming plugin. I am working for the Education Ministry of Quebec/Canada Government, and we are looking for an open-source alternative to ESRI topology tool in order to reduce the cost of licenses.
Thank you for your support.

Hi,
You might also want to take a look at OpenJUMP,
which already has a complete set of tools for
conflation tasks:
http://openjump.org/
Also, gvSIG CE (http://gvsigce.org) has a rich
toolset for topological cleaning of shapefiles
and comes with GRASS-support built-in.
Best,
Ben

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

Thank you Tereza for your quick reply,
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.
Saluations,
Max Demars
