[postgis-users] The pcpatch datatype

[Jonathan Moules]

Hi List,
I'm new to PostGIS and have inherited a database which is being used to store a pointcloud.

The data seems to be in a "pcpatch" Data type, and this is being converted into points for extraction with: "select pc_explode(pa)::geometry ...".

The problem is, I can find no reference to pcpatch in the PostGIS documentation, or to the pc_explode function. I've tried both the online search and Ctrl-F in the PDF.

Is there any documentation for this? If so, can someone please point me to it that'd be really useful. Alternately, an explanation of the datatype would be useful. Is it WKB?

I've figured out that the "::" (double colon) is casting the result into a geometry data type, so that's one less problem. :)

PostGIS 2.1.3

Thanks,
Jonathan
