How do I use GDAL to convert from an arbitrary projection/datum into Equirectangular/WGS84? This is a cross posting: lists.osgeo.org/pipermail/gdal-dev/2010-November/026929.html |

What are the valid values for “band” in a GeoTiff file? I created a 40K band GeoTIFF with rgdal, so I know at least it's not limited to 32768 :) |

What are the valid values for “band” in a GeoTiff file? Are you worried about limits on the number of bands? Do you perhaps want a multidimensional array (say NetCDF or HDF format) rather than a GeoTIFF? Multiple bands are sometimes used to stored an "unrolled" array in a 2d raster (this is how GDAL will represent NetCDF/HDF and others), but it's not exactly ideal. You might want multiple attributes on a multidimensional array, and GIS formats are not generally suited to this. |

How can I work with 3+ Gigabyte TIFF Files? If you use tiling and compression the conversion will be more efficient and the result smaller, if your other software can support that. Use -co TILED=YES -co COMPRESS=LZW for simple options with gdalwarp. You should be careful to use BigTIFF variant as well for very large files. |

How do you best deal with data that spreads across UTM Zones? What do you mean "lines as lines (not arcs)"? It correctly represents loxodromes as straight lines, and it's famous for that because of ocean navigation by compass, and for being a simple projection to generate. |

How stable is MapWindow on a 64 bit machine open bugs are a fact of life, this answer would be useful if there were some insight about the bugs referred to in the context of the software |

How stable is MapWindow on a 64 bit machine this has nothing to do with GIS, it's a question about software support |

Color palette conventions below you clarify you are looking for colours and "their meanings", though here you say you are looking for conventions |

Color palette conventions really? how is the question not hopelessly subjective? Colours don't have meanings, all that anyone could do is point to existing conventions - Brad's links seem fine |

How do you best deal with data that spreads across UTM Zones? NSW and VIC? There's no easy way to do this without adopting one or the other projection (or your own) and just transforming between different data sources as required. |
