What's the difference between gdalwarp and gdal_merge for mosaicing Had no idea about this tuning switch, which indeed speeds up the process. For reference 3000 is 3GB (more info trac.osgeo.org/gdal/wiki/UserDocs/GdalWarp) I have NumPy build with MKL in my system Python, but still gdalwarp must be doing something more, as NumPy can't be faster then C implementation, although can reach it. |

How to re-project shapefiles? Thanks I didn't know about that, and Googling it showed me what you meant. It's exactly what I needed. If you could have only posted your last comment yesterday... I did lot of typing to get there ;) |

How to re-project shapefiles? I was trying to overlay vector layer from one projection (epsg:31277) to another (epsg:4326). However I did not understood this well, as now I know that I don't need re-projection (changing the shapefile data) but just change to shapefile projection file (.prj) by using -a_srs instead -t_srs. Issue why EPSG:4326 SRS that didn't had projection, was because it's WGS84 geographic coordinate system, so it doesn't need projection, as was shown to me by others. |

How to re-project shapefiles? I tried different projections and they all output very different values for coordinates. I'll ask at gdal mailing list, and post results if I get answer. Thanks for your time |

How to re-project shapefiles? With EPSG:900913 instead EPSG:4326 I get "PROJCS["Google_Maps_Global_Mercator"... but coordinates are totally off :Extent: (-3785362.530285, 25.607240) - (-3785362.528919, 25.608223) |

How to re-project shapefiles? But it's not projected. PROJCS dictionary is not present in metadata and coordinates are wrong. See the coordinates (Extent) in source file and then in file output by ogr2ogr. |

How to re-project shapefiles? But it just changes coordinate system without re-projecting. That's why I asked this question. Please see the code box in my question more closely |

How to re-project shapefiles? @steko: If "on the fly" is what is answered by djq, yes I already knew that. |

How to re-project shapefiles? Yes that's great, but I would have to do that for every layer, which is time consuming. By using command line I was hoping to re-project all shapefiles at once (with for loop) |
