I have experimented with creating the data for an image pyramid. I have created
a set of files in a folder structure like in the following example:
Pyramid:
0:
12:
GeoTiffs
13:
GeoTiffs
14:
GeoTiffs
1:
6:
GeoTiffs
7:
GeoTiffs
2:
3:
GeoTiffs
If I try to create an image pyramid through Geoserver using the ImagePyramid
plugin, it creates a pyramid from level 0 only and returns without errors. The
shape file from level 0 seems to include all the Geotiffs on that level. I
would expect however, that the pyramid included level 1 and 2 also, but it
doesn't.
It seems as it doesn't see the two other levels, so is there a file name
convention for the Geotiffs when using Geoserver to build the pyramid?
Currently my naming scheme is <tilesize>_<northing>_<easting>.tif
And is there another way to build the pyramid without using Geoserver to build
the index files? I have a rather large set of files and I don't want the
geoserver to use resources on creating the indexes if I can do it on a
workstation instead.
I have found this blog entry [1] by Simone, but again it is using the Geoserver
and I couldn't even get it to work. => Could not list layers for this store, an
error occurred retrieving them: Unable to acquire a reader for this coverage
with format: ImageMosaic
