<br><br></div><div class="im">Edi,
<br><br>Generally speaking, as long as you enable internal tiling when building
<br>the mosaic there is no need to break it down into separate files.
<br>Add '-co TILED=YES' to the gdal_merge.py command to produce an output
<br>GeoTIFF file that is internally tiled.
<br><br></div><div class="im">> And how can i find in which scale should i switch layers? So what will be

<br><br></div><div class="im">That remains a complicated question. I believe I suggested 1/32 as a
<br>good overview level since beyond that point a normal map view will tend
<br>to involve a significant number of files.
<br><br></div><div class="im">> if ill still have performance problems, or ill get 1-2 terabytes of data

<br><br></div><div class="im">I presume as you add data, your area is growing. If that is so, the 1/32nd
<br>overview level is still appropriate, and you just need to regenerate the
<br>overview for the larger area.
<br><br>If you are using MapServer and GDAL then there is no real problem with using
<br>one large geotiff file for the overview as long as it has internal tiling,
<br>even if it grows to many GB in size.
