[mapserver-dev] Point Clouds, reprojecting . . .

[Howard Butler]

Bobb,

Describe a bit more detail of what you want to do. You're correct that Entwine/EPT is a static resource. You can also reproject those points in your browser with Javascript. PDAL can use readers.ept to reproject batches of them however you want.

I would think MapServer's per-point overhead would get rather high to do it in MapServer.

Both Entwine and potree seem to be only one coordinate system at a time products, so converting between them seems the way forward if possible.  I’m familiar with the MapServer methods of reprojection, etc and started there (here?).  the Mapserver pipelining seems to lend itself to this task.

Moving forward, MS4W will be including PDAL-latest in every MS4W release (there is already tickets for specific plugins to add in the next release). Cool!
