[mapserver-users] Automatic simplification based on resolution

[Basques, Bob (CI-StPaul)]

I was wondering about possibly using variable patch sizes( number of points per patch) inside of the pointcloud to do something like this.  I don't know how much replication you might need, but I was willing to try some ideas related to a Pyramid of Pointcloud features, just need to figure out how to process the pyramid down from the raw data . . .

One quick way to test might be to make resolution/cellsize values available for use in PostGIS SQL kinda like the !!bbox!! hack Paul made available years ago, perhaps !!cellx!! and !!celly!! and then one could pass those as necessary to the simplification function or their choice?

Hi,

Mapnik has such a feature http://blog.cartodb.com/post/20163722809/speeding-up-tiles-rendering
Andrea Aime is experimenting with it with Geoserver and is reaching a 50% speedup.

Can Mapserver do the same?
