[postgis-devel] Planning of raster work to be integrated in PostGIS 2.0

[Pierre Racine]

Hi all,

As you probably noticed, Bborie Park from the Center for Vectorborne Diseases at the University of California, has been very prolific over the last week adding a significant number of functions to work with the raster type. He finished all the functions listed below (more are to come later). 

My question goes as follow: 

1) Should we make the effort (and take the risk) of integrating his work for PostGIS 2.0 or should we wait for PostGIS 2.1? Note that these functions are not documented yet.

Sub questions are: 

2) When is the feature freeze planned? Is there going to be a branch done? How do you usually deal with future stuff to add during a release cycle?

3) When is the code freeze planned?

-----------------------------
Functions to integrate (each function have a certain number of variants):

ST_Band(rast raster, bandnums int[]) #339

ST_MinMax(rast raster, nband int, ignore_nodata boolean, OUT min float8, OUT max float8) #902

ST_ApproxMinMax(rast raster, nband int, ignore_nodata boolean, sample float8, OUT min float8, OUT max float8) #902

ST_Reclass(rast raster, nband int, reclassexpr text, pixeltype text, nodataval double precision) #903

ST_AsGDALRaster(rast raster, format text, options text[], srs text) #901

ST_AsTiff(rast raster, options text[], srs text) #341

ST_AsPNG(rast raster, options text[], srs text) #342

ST_AsJPEG(rast raster, options text[], srs text) #340

Thanks,
