[gdal-dev] GSoC 2016

Hello everyone

I am a second year student at Saint-Petersburg ITMO University, Russia. For GSoC 2016 I would like to work on DWG support in GDAL.

Overall idea
DWG  is very wide-spread format and it seems like there is a lot of requests  for a good conversion tools from DWG to more common spatial data. I  think that current implementations of DWG support are not optimal. For  example libdwg (abandoned), libredwg (GPLv3 incompatible with X/MIT).

Technical details
I plan to use the existing DXF driver as origin for DWG driver. The driver will not have any third-party dependencies. First of all I'll study ODA DWG specification and how DXF driver works. Than I plan to create DWG driver skeleton. And finally code some scope of functionality (will be defined later). I'll be grateful if somebody share some dwg test files with common cases.

Possible problems
There are near 7 versions of DWG format (R13, R14, R2000, R2004, R2007, R2010, R2013) with differencies in file organisation, so driver should be able to read from and write to all of them.

Currently I'm familiarizing myself with GDAL source tree, compilation etc. I'll send another email with some progress on other GDAL issues I was trying to fix.

I'm excited about the opportunity and hope to be useful for the project!

Cheers,
Alexander
