<div dir="ltr"><div>Hi all,<br></div><div>Please find the GSOC Weekly report 1 in the following email.<br><br><br><b><u>Weekly report 1</u></b><br><br></div><b>What was done this week?</b><br><div><ul><li>During the bonding period it was decided after discussions with the
mentors that we would create the plug-in by integrating it with the
already existing functions of <a href="http://www.qgis.org/en/docs/user_manual/processing/toolbox.html" class="">Processing Toolbox</a>. So this week mostly took to getting acquainted with various different functionalities of the toolbox.<br>
</li></ul>
<ul><li>For simplification of geometry, <a href="http://www.qgis.org/api/classQgsTopologyPreservingSimplifier.html" class="">QgsTopologyPreservingSimplifier</a>
class will be used as the implementation is similar to Douglas Peucker
algorithm and also gives us the advantage of preserving the topology.
There were some errors in the output for some data sets but otherwise it
is working good enough. Those errors are reduced if we are merging
small segments of the lines and then splitting them at the intersection before simplification.</li></ul><p><b>What is the plan for next week?</b><br></p>
<ul><li>Implement a basic plug-in which removes objects smaller than a
certain threshold. This would be a good start and will provide an initial setup for the plug-in and
act as a base for it. This function for removing the smaller objects
might create topology errors, so this would be available as an option in
the plug-in.</li></ul><p><br></p><p>More details at : <a href="http://hub.qgis.org/wiki/quantum-gis/nishithm">http://hub.qgis.org/wiki/quantum-gis/nishithm</a></p><p><br></p><p>Thanks and regards,<br></p><p>Nishith Maheshwari<br>
