Hi,<br><br>If I need to be able to mosaic tiles together but do not need to change the projection, then I can run gdal_merge which will run faster than gdalwarp.<br>My question is their any advantage to running gdalwarp as far as:
<br>1.) data quality<br>2.) scalability: I will be mosaicking many gigabytes (5GB-100GB) worth of tiles together will gdal_merge be able to handle this?<br><br>Thanks,<br clear="all"><br>-- <br>John J. Mitchell
