comment Polygon rendering issue in map composer, QGIS 2.8
What projection are you using and where did you get the data. The fault may well lie in the original data which might have been tweaked to avoid the pole as in most non-polar coordinate systems, this would result in an infinitely long line and the data provider may not be expecting you to map to the pole itself

comment Checking if point is inside irregular polygon?
There are two solutions. One is labelled as the solution which finally worked. If you don't like that solution I suggest you look at one of the NPM resources and adapt the code there to your purposes. However, without knowing how you implemented the solutino I can't say any more.

comment Converting from unknown coordinate system into common one using fiducial points?
As Andre says: 'GIS libraries can reproject almost every "old and odd" coordinate system'. Does QGIS recognise the projection? If so, just do 'Save As' and define the new projection for the ouptut in the dialog box.

comment How can I create fly through using contours to visualize cadastral parcels?
There are many threads on similar topics on this site (try searching on 3D visualization). There are also a vast number of possible approaches and much will depend on your level of experience and the software you have available to you. Please edit your question to add more detail if one of the other threads does not help.

comment Averaging multiple values to a single value by common field ID
It sounds like you have some duff data (looks like you have a point or polygon will Null Geometry). If that's the case you need to eliminate it. see here gis.stackexchange.com/questions/74243/…

comment how to extract a rectangle corner coordinates in python script
No. Ogr is for vector data. You need to call gdal functions, but see my edit above.

comment Creating tile server from geotiff
I can see the benefits of that too, although the GeowebCache directory structure and naming conventions follows the standard z,x,y plan so, you still do have straighforward access to the tiles directly without needing to use a service is you so wish.
