Geowebcache is used for caching tiles to improve speed, not controlling layer visibility There are two ways to handle layer visibility Style the Layer using SLD in GEoserver, using<MinScaleDenominator></MinScaleDenominator> and ...

You might consider using the Visibility Index, which is a measure of the size of the viewshed for each pixel in a DEM. This way you could measure the overall visibility of a pathway or route. I wrote a blog on the calculation of the visibility index and some of the challenges involved that you might find useful here: ...
