Fixed per http://trac.osgeo.org/gdal/ticket/5961 Even Hey guys, We have DigitalGlobe image strips which come with a *.til file. The geotransform of the til and the separate images have a shift of half a pixel when opened with GDAL. The reason is that in the GDAL TIL driver the coordinates are treated as outer pixel edge, where as it seems like they describe the pixel center, at least in our cases. Does anyone know of a description for the TIL format to verify if the GDAL driver or the TILs from DigitalGlobe are wrong? For now we fixed it on our side, but you might consider changing the TIL driver to treat the coordinates as pixel center.

Re: [gdal-dev] [Live-demo] [Board] Retire MapTiler from OSGeo-Live
I agree with the significance gdal2tiles. I've used on numerous occasions and it would a shame to lose it.

The duplication between gdal2tiles.py in maptiler and GDAL isn't something particularly great. Ideally there should be one single version maintained in the OSGeo ecosystem. So there are several possibilities I can imagine : 1) Merge maptiler's gdal2tiles enhancements into GDAL version, and make maptiler just a GUI over it 2) Merge maptiler's gdal2tiles enhancements into GDAL version, and also import the GUI (I think it is lightweight) if there's no too strong build complications involved for GDAL. Would have to be checked 3) Remove gdal2tiles from GDAL so that the reborne maptiler is the reference. But there are perhaps fixes in GDAL gdal2tiles that should be merged into maptiler one (Python3 compatibility comes to mind) Any option would need someone to champion it of course... IMO, the third option should not be considered at all, since gdal2tiles is very important tool in gdal and many people (including me) prefer the script from any GUI out there. I have also seen an improved version of this script dealing with multiple threads. My preference would be option 1. Just my 2c :) Even Hi Eli, replying to your email, CC OSGeo-Live list (with your permission). I agree that we don't want to be promoting a proprietary product from an Open Source page.

This way we can prove that the project was open source and can be forked in the future. Unfortunately the main repository of the project was recently deleted. Without this, one can have the impression that OSGeoLive and OSGeo has endorsed and distributed proprietary software. Also we plan to introduce IceTiler in the next version of OSGeoLive. For this OSGeo-Live release we will do what we can achieve within the time available.

Linking to the last open source code with no name makes more sense to me (I know that isn't possible unless we put the code somewhere). Or linking to http://gdal.org/gdal2tiles.html which has some similar functionality and common ancestry. Looks like maybe licenses have varied in different points in time from different sources too. On the short timeline, there is no fork and no name to link to yet. If there were a fork and name would you list and link that? If so would you list or link MapTiler too? You could link (or save all

Re: [gdal-dev] elevetions from ASTER GDEM V2
If the spatial resulution is fine for your problem, then as Tyler suggested, you can use gdallocationinfo [1] to get the pixel value at Long,Lat location. If you think you need to downscale your data to your needs, you can first built a vrt (virtual dataset) with gdal's gdalbuildvrt [2] and -tr option. What I don't know is, which method vrts are using to obtain raster values when the source rasters are in another resolution than the vrt [1] http://www.gdal.org/gdallocationinfo.html [2] http://www.gdal.org/gdalbuildvrt.html On Thu, Jan 24, 2013 at 10:15 PM, Tyler Mitchell tyler.mitch...@actian.comwrote: On 2013-01-24, at 11:43 AM, Elias Kotsifis wrote: I want to calculate the elevation of any point on earth, giving lat, Long (for example like google elevation Api, or the earth tools: http://www.earthtools.org/webservices.htm # cheigit) based the ASTER GDEM MODEL V2.
