I'm a software developer, focused on GIS. PostGIS and GDAL committer. I'd love to add 'where' to people's lives.

How to add color interpretation for raster bands using GDAL? I actually did that, but I get "ERROR 6: SetColorTable() not supported for multi-sample TIFF files.". And I get 0 for all pixels. I'm not sure about the meaning of this error. |

How to add color interpretation for raster bands using GDAL? No,they all have the same geotransforms,but they're no north-up rasters (rotation parameters are not 0). And gdalbuildvrt does not support rotated geo transforms. I don't want to warp them. |

What is the fastest (performance-wise) way to serve PostGIS features? Thanks! The project was finally cancelled, but I think your solution is a good one. |

How could I make this PostGIS query run faster? Not exactly. I wrote the GDAL PostGIS Raster driver, and helped with PostGIS Raster extension (did some functions, mostly related with GDAL). I know the raster-polygon intersection implies the polygonization of the raster previous to intersection. That could be a heavy process. I don't know if there's some PostgreSQL specific thing I can do to make it faster without changing PostGIS Raster internals. |

Why does gdalbuildvrt not allow these things? Yes, I'm actually using VRT driver to develop my own one. I've read, in several places, that is hard to work with rotated rasters. Tools like gdal_translate or gdalbuildvrt doesn't work in the input raster(s) is (are) rotated. So, why is so difficult? Isn't enough with the GeoTransform array? |

Why does gdalbuildvrt not allow these things? Ok, thanks for your response. I think I'm going to look for information about merging rotated images. I know it's difficult, but I don't have enough background to argue why. |
