Hi Leandro,
You can try VPB (Virtual Planet Builder for this). It should take care
of splitting and merging of datasets in the result-tiles if they are
correctly geo-referenced.

Hi,
I have a region of terrain represented with 5 datasets. One dataset for
elevation (a geotiff file) and four datasets of satellite imagery (jp2 files).
Each satellite imagery covers a different quarter of the region, covering the
full region all together (like a quad-tree structure with elevation al level of
detail L and imagery at level of detail L+1).
This is all data I have and I want to visualize this data using osgTerrain
library.
I can't use this data as it is in a osgTerrain::TerrainTile because I must
cover the same terrain region in color and elevation layers associated to the
TerrainTile. First question: Is that right or am I missing something?
If i don't missing something, in order to use osgTerrain::TerrainTile I need to
join the four imagery datasets in one dataset or split the elevation dataset in
four datasets.
I decided to split the elevation data. So, I made four gdal_translate calls to
generate the new four elevation datasets, I created four TerrainTile nodes and
associated a pair of elevation-imagery datasets for each TerrainTile (as
osg::Heighfield's and osg::Image's) and it's working ok.
Second question: is there a way of splitting directly the osg::HeightField
instead of splitting the geotiff file?
Thank you!
Cheers,
Leandro
