Climate Maps on commons from Hessd
Hello Toran,
I am writing you because of this image you uploaded on commons: commons:Image:Köppen-geiger-hessd-2007.svg and related images. You write that the original map was from HESSD. Although the map you used is not there anymore, because it was not yet peer reviewed. You say the map is under a Creative Commons License, that is correct, but the map you used is under a "Creative Commons Attribution, NonCommercial and ShareAlike Licence", but that license is not compatible with the free licenses we use on Wikipedia. That's why I wrote an e-mail to Australia on April 21th this year. Dr Peel, who made these maps, told me that we can use the maps under a compatible Creative Commons License after the peer review is completed. That is done (after almost 6 months). So I uploaded the maps we can use and made a bunch off other maps from the original. See here.
He explicitly told me not to use the not yet peer reviewed maps, so I ask you nicely if you can delete the maps you based on the not yet peer reviewed maps? I know they are not exact copies, so we are in a gray area, but we can now have the original files and I like to have a good relationship with the folks in Melbourne. Off course you can still use the new peer reviewed maps to produce custom maps (I saw you made some). Hopefully you understand my non native English.
Cheers,

- I understand the problem, but I don't want to delete my works without providing a replacement. I am willing to start over using the peer-reviewed maps and upload them as new versions, but I need something without the country borders because I have to vectorize the map as a starting point. Do you have the original map available in PDF or EPS format? IIRC the climate data, coast lines and borders were seperate overlays in that file.
- I would be glad to hear from you soon, --LordToran 15:14, 13. Okt. 2007 (CEST)
- Hi Toran,
- Thank you for your answer. I agree with you, if you want to keep the files until you have provided updated versions based on the peer reviewed maps.
- Although I asked to Dr Peel if he can provide vector based maps, like SVG, he made a JPG file :-(, although I explicitly told him not to use JPG for maps. Oh well, you can't have everything and I'm happy that he gave his scientific work to Wikipedia. You can find a PDF, but not a EPS on http://www.hydrol-earth-syst-sci.net/11/1633/2007/hess-11-1633-2007.html . The "Supplement" is a ZIP-file, with a very large JPG and also ArcMap-data. I can't read that on Linux and on Windows you need commercial software to be able to read it. I searched the internet for two hours to find a viewer, but I had no success. Maybe you have more luck.

- Yes, I already found and downloaded the PDF and supplement yesterday and ran pdftops and pdfimages on it. In this version of the PDF, all the maps are plain raster graphics. In the older version, the climate data was a bitmap with the coastlines and borders being a vector overlay. In other words, it is near impossible to edit the current map :-(
- I also tried loading the ArcMap data into GRASS (specifying the .rrd file as the dataset), but the backend complained about some missing definitions in the file when I tried to render the map.
- Could you ask Dr. Peel to provide a map without the borders and coasts (doesn't matter whether it is bitmap or vector format)? It is the only way one could create a derivative map. I am quite good with graphics retouching, but I see no way how to edit out the borders without considerable data loss, because they are thick, opaque and antialiased.

- Success! I managed to extract the data from the .adf files as .tif files, using gdal_translate :-) So you don't have to nag the professor any more with this. I will upload updated versions of all my climate maps during the next days. If you are interested in obtaining the data yourself, try the following in the directory with the .adf files:
gdal_translate -scale 1 32 64 254 -a_nodata 255 ./w001001.adf koppen_data.tif
- You must have the gdal-bin package installed for this.
- Great :-). This is a huge step forward. Thank you very much for your great work Toran. Jeroenvrp 20:29, 14. Okt. 2007 (CEST)
