CRS parameter for encode() function

[Piero Campalani]

Petascope should not pass the URI as crs parameter of the [RasqlEncodeFunction encode] function of RasQL since only opengis ones are recognized.

I suggest that Petascope sets the crs in EPSG:CODE format. Non-EPSG ones will not be embedded in the file anyway.

Alternatively Petascope would personally fetch the definition and translate it to PROJ4 or WKT format, and pass it on to the encode function: this would be the ultimate solution to deliver proper CRS information for any CRS. This involves time CRS too.

$ rasql -q 'select encode( c, "GTiff", "xmin=111.975;ymin=-44.525;xmax=156.275;ymax=-8.975;crs=http://www.opengis.net/def/crs/EPSG/0/4326" ) from mean_summer_airtemp as c' --out file
