[Ica-osgeo-labs] [OSGeo-Edu] ACM SIGSPATIAL contest

[Suchith Anand]

Hi Stefan, 

Thanks for this info. There is also a QGIS Schematization Plugin that was proposed by  Luciene Delazari along with Mark Ware and myself for this year's Google Summer of Code. Details below:

In the current version there are few tools for generalization (Dedicated to line simplification). It would be a great improvement to have some functions to create schematic maps, for example:

   #   Simplify lines - input data will typically contain redundant vertices. These are removed by application of a suitable line simplification algorithm (in our case the Douglas-Peucker algorithm). For example building on the QGIS generalize plugin
   #   topology - ensures that original map and derived schematic map are topologically consistent i.e yopology of the network is preserved during the schematization process.
   #   angular - if possible, edges should lie in horizontal, vertical or diagonal direction.
    minimum edge length - if possible, all edges should have length greater than some minimum length.

In future, we can add more functionalities by adding constraints on Rotation, Clearance, Displacement etc.

It will be good opportunity if we can implement this as plugin in QGIS.

Hi all,

the ACM SIGSPATIAL contest this year is about a map generalization task.
If someone has interest or interested students, please forward:

http://mypages.iit.edu/~xzhang22/GISCUP2014/

would be interesting to see also how standard FOS desktop GIS perform on this.

cheers,
stefan
