Line topology edits
Posted September 12th, 2008 by Anonymous
Hallo my naam is Pieters. Ek praat Afrikaans en is van Suid Afrika.
In case Afrikaans is not understandable I will continue in English. My language is close to Flemish and is derived from Dutch.
I work on the street center lines of South Africa. I'm looking for a web based solution for editing the data, MAJAS looks like an option. I have one question. Can it handle topology. I'm not sure if I use the term correctly. What I mean is a link in the line network has a start node and end node or end points. At an intersection two or more links are connected to one another. So if I move that endpoint will all the links that are connected to that endpoint move along? If you know Maptitude GIS from caliper - the way they handle this is very user friendly and I'm looking for something similar but Web based.
Regards,
Pieters.
Hello Mr. Pieters,
I speak Flemish, but I will try to answer in English.
The topology possibilities where built into a project for a
Flemish user. We are integrating and testing this code now to be
available in the next stable release of geGIS. We already have a
developer version ready where topology is supported.
We also have created a module which supports open street map data.
We will demonstrate this module on a FOSS4G2008 work shop, in south
Africa (Kaapstad) begin of october. (together with the Topology
stuff). You can find more information about this workshop on:
http://wiki.osgeo.org/wiki/FOSS4G2008_Workshop_Submissions
look for the submission of Pieter De Graef.
I'll keep you informed when the topology features are on-line.
regards,
Dirk Frigne
PS. (in Dutch) Ikzelf zal op de FOSS4G2008 conferentie een
presentatie geven rond de stand van zaken van het geGIS 2.0 project
en hoe je hiermee een editeerbare SDI node kan meeopzetten.Als je de
kans hebt om naar dit congres bij te wonen, kijk ik er naar uit om je
daar te ontmoeten.
Hello Pieters,
This is unfortunately not supported for the moment, it's a good idea though. But we don't have a standard function that supports this for the moment.
Many regards
Frank Schram
