How to run sextante algorithms outside of qgis python console? Hi Victor, is this still the case? I'm struggling with how to call Sextante in a standalone script (outside of QGIS) and finding all examples I google to not work. This was posted a year ago so I wonder if the architecture of sextante has changed? |

Can I access a raster attribute table in QGIS? @GiovanniManghi would you mind posting your comment as an answer so you can get the "rep"? |

Can I access a raster attribute table in QGIS? @R.K. The link points to a ticket to unimplemented feature request from a year ago. Do you think that would be helpful as a answer to this question? Happy to post if so. |

Can I access a raster attribute table in QGIS? Yes that's exactly what I'm looking for. Surprised to see the comment "this suggestion comes from Arc* users". I'm new to the gis world, but seems like attribute tables with rasters are a useful feature. |

GDAL RasterizeLayer Doesn't Burn All Polygons to Raster Can you provide a link to 'activity_3.shp' and 'AOI_Raster.tif'? I want to see if I can recreate on my end. |

Can I create blended images with GDAL command line utilities? FYI, the blend function turned out to be the most helpful for what I was trying to do. |

GeoTIFFs made in GDAL don't have min/max range when loaded in Arc/QGIS Thanks, this did the trick, and thanks for the context. By the way, I was able to nest the band reference without a temporary variable with no problems. |

How to add different sized rasters in GDAL so the result is only in the intersected region It makes perfect sense, thank you! |

Want to use GDAL in Arc10 toolbox via subprocess call Thanks for checking; I read that post as well. Unfortunately updating the os.environ['PATH'] before loading gdal didn't work either. |

Want to use GDAL in Arc10 toolbox via subprocess call Unfortunately sys.path is identical between the two calls except for an extra directory. If I manually remove that directory I still get the same error. Any other ideas? |

How do I convert affine coordinates to lat/lng? Maybe this is what I'm after. Is the "epsg:4326" a transform to global lat/lng? I think I see some classes where I can provide a projection, I was thinking "WGS:84", but I don't know the difference. |

How do I convert affine coordinates to lat/lng? I read the geotransform section of the link you provided, but I don't think this is what I'm after. Sorry if I am being obtuse, but doesn't this describe how to project x and y indices (0 to XSize or YSize) to projected coordinates? I'm curious how you translate projected coordinates into latitude and longitude. As a simple example, the geotransform defines the x/y origin of the upper left hand corner of the raster in projected coordinates (447466.693808, 4952570.40529). How would I turn those coordinates back into lat/lng (something like lat: 44,lng: -122). |

How do I convert affine coordinates to lat/lng? @Dan Thanks, so I know I can get the projection via a dataset.GetProjectionRef() and find out I'm using "UTM Zone 10", but then what? I'm googling around for methods like "unproject" but am coming up null. |
