[gdal-dev] WKT Raster driver in GSoC 2009
Dear Community, I've added proposal of GDAL Driver for PostGIS / WKT Raster to the GSoC 2009 list [1]. I hope you don't mind. [1] http://trac.osgeo.org/gdal/wiki/SummerOfCode If there is anyone interested in working on this project, I'm willing to mentor it.

Re: [gdal-dev] WKT Raster driver in GSoC 2009
Hello, I've just send a mail about GSoC 09. This is one of the projects I'm interested in. What skills are required/strongly desired (apart from knowledge on C/C++)? What difficult level would you assign to the project? Oh, you may prefer to answer my other e-mail :-) Best regards Jorge On Sun, Mar 29, 2009 at 3:16 PM, Mateusz Loskot mate...@loskot.net wrote: Dear Community, I've added proposal of GDAL Driver for PostGIS / WKT Raster to the GSoC 2009 list [1].

[gdal-dev] OGR + ArcSDE: support for non-spatial tables
Does anyone know if there's support for non-spatial tables in ArcSDE through OGR? For instance to make a join with a spatial table? Thanks, Duarte ___ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev

In the proposal, I specified more elements: raster graphics, basic understanding of Well-Known-Binary-like formats, libpq, C (strong), C++ (basic). In my opinion, it's recommended that a candidate understand/know: - raster - band - pixel and how pixel type influences raster structure - recognize BIP, BIL and BSQ layouts - reading and parsing binary data in C/C++ - encode/decode raw binary data to/from hex in C/C++ - understand idea behind Well-Known-Text and Well-Known-Binary - understand basics of architecture of GDAL - understand basics of PostGIS - how to write good unit test for GDAL driver - how to use GDAL, PostgreSQL and PostGIS manuals and websites What difficult level would you assign to the project? As I've explained, I'm unable to judge this aspect. Oh, you may prefer to answer my other e-mail :-) Actually, I'd strongly encourage to discuss everything on public forum. As this is about GDAL driver, then gdal-dev is probably best place for discussing it.

Re: [gdal-dev] Questions about projects of GSoC 2009
Hello, Difficult is a very subjective thing, totally agree. Sorry for the approach of the question. Maybe I can raise it in that way: What amount of theoretical/practical knowledge do I need to start working on the project? For example, the first project (PNG driver) suggests me the following initial knowledges (most of them are specified in the web http://trac.osgeo.org/gdal/wiki/SummerOfCode): - PNG format (of course) - C / C++ fluently - Raster, bands - Basic GDAL architecture - NeuQuant algorithm - Kohonen Neural Networks - pngnq - Several tools that optimize PNG The project about WKT raster (the list that you provided me on another mail): - raster - band - pixel and how pixel type influences raster structure - recognize BIP, BIL and BSQ layouts - reading and parsing binary data in C/C++ - encode/decode raw binary data to/from hex in C/C++ - understand idea behind Well-Known-Text and Well-Known-Binary - understand basics of architecture of GDAL - understand basics of PostGIS - how to write good unit test for GDAL driver - how to use GDAL, PostgreSQL and PostGIS manuals and websites All concepts sound familiar (because I've studied or worked with them), but I think that I need some previous time to go deeper. I have to include this in my schedule. I'll finish it tomorrow, and we'll be able to go further on this issue, if you want :-) Thanks for your response Best regards Jorge 2009/3/29 Mateusz Loskot mate...@loskot.net Jorge Arévalo wrote: Hello everybody, I'm interesed in these projects: - PNG Driver - WMTS implementation - WKT Raster Driver Great! I would like to know a little more about them. Do you have any specific questions or concerns? Basically, their estimated difficulty. Difficulty is a subjective thing. What is difficult to me, might be easy to you, so estimation may be lead misleading. I'm very exciting about the possibility of being one of the selected OSGeo students for GSoC 2009, but I think that I need to be realistic and totally comitted with the project. I'm making a schedule, and I would like to know if all projects fit into it. And, what's your schedule? For example, the last two projects seem to be longer that the first one, but maybe I'm wrong. Exactly, seem is the right word. We don't know what's your experience and what you consider as easy/difficult. So, it's very hard to help you in making your decision unless you have specific / technical questions. Remember, that GSoC projects are not managed in the commercial way. It's you and mentor who agree that a project is completed or not. See Q9 and Q10: http://code.google.com/opensource/gsoc/2008/faqs.html#0.1_use_code So, I'd not worry much about making a very detailed timeline plan. For instance WKT Raster driver, as I mentioned in the proposal, the idea is to develop a *prototype*, something that proofs (or not) the concept is feasible and implementation may perform well, something that will be helpful and usable for further development.

[gdal-dev] convert qct format to geotiff
Hi, Hope this is the right list. I have topo maps in qct raster file format. QCT file is proprietary format from Memory Map: http://www.memory-map.co.uk/ Searching for a free converter I found this link: http://mail.python.org/pipermail/python-list/2007-December/641555.html Conversion seems to work on limited size 2000 x 2000 pixels and doesn't preserve rectification. Is there a gdal workaround to convert them into geotiff? -- cheers, maning -- Freedom is still the most radical idea of all -N.Branden wiki: http://esambale.wikispaces.com/ blog: http://epsg4253.wordpress.com/ -- ___ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
