My Question:
Is there any way to control the scale/zoom level "entry" and "exit" points
for each level of a pyramid?
Background:
I have a few gigs worth of map tiles at different map resolutions.
However the step between the resolutions is not 0 2 4 8 16 etc it is more
like 10 20 40 200 1000.
I am using the layers I already have in my pyramid rather than creating
overviews from the bottom layer.
I have created an imagemosaic for each level of the pyramid.
I then created an imagepyramid and imported it into GeoServer using the
ImagePyramidal plugin.
I am using OpenLayers to view my result.
I get seamless zooming between the different layers and all the levels show
up.
The problem I am facing is that it enters and exits the levels too early and
hence its a little slow and shows too much complexity on the map at certain
zoom levels. Is there a way to control which level of the pyramid is shown
at a particular scale or zoom level?
I could create intermediate levels within my pyramid using gdal_warp by
simply halving the size of the original map tiles but this seems like a
cumbersome and unnecessary workaround as I already have enough levels to do
what i want to do - i just need to control what is displayed when.
Sorry if my terminology is incorrect - i am from a telecoms background and a
GIS novice.
Thanks
James
