Hello Klokan,<br>
<br>
Thanks for encouraging me! And congratulations for your excellent job
with gdal2tiles. It really saved me from a lot of unproductive hours...<br>
<br>
It would be great to help you with WMTS implementation, or work with
PNG driver, or with WKT Raster driver. I'm going to apply for the three
projects directly on the GSoC page. Frank Warmerdarm told me on the
GSoC list that it was the correct way. Am I right?<br>
<br>
Best regards<br>
Jorge<br>

Jorge,<br>
<br>
I am glad you are interested in the PNG driver, which I suggested as a<br>
project for Summer of Code...<br>
It would be really great to have this in GDAL and I guess more<br>
projects will profit from this...<br>
<br>
I am going to assist as much as I can, whether in gsoc program<br>
timeframe or even otherwise.<br>
Feel free to contact me with any questions related to this project...<br>
<br>
I guess for position of mentor there are better candidates then me<br>
(like Frank, Even, Mateusz, ...)<br>
<br>
Because I am a PhD student I applied in this Summer of Code as well as<br>
a student so I technically I can not be your mentor. I can work this<br>
summer on the WMTS implementation and other GDAL2Tiles improvements...<br>
but I don't want to block position of new candidates...<br>
If you are interested in WMTS implementation and GDAL2Tiles then just<br>
go ahead, this I can mentor for sure ;-)<br>
<br>
Best regards,<br>
<br>
Klokan<br>
