[postgis-users] point to raster conversion

[Rémi Cura]

Hey,

not very original question :
I would like to convert parts of a point cloud into a raster.

I'm under the impression that currently this is more easily done outside
PostGIS (with grass, gdal, R, or wathever).

I this simple process a good idea?

for each small part of point cloud (a patch)

get spatial extend

generate a raster covering this extand with givenpixel size and given bands

for pixel which intersects a point, set pixel band values with point
attributes


Then (optionnal)
for each raster

use efficient image processing code to interpolate

Cheers,
Rémi-C
