Occassional Unknown node for ScaleCoverageExpr expression: trim error.

Description

I'm getting an odd behaviour from our rasdaman 9 service, compared to our rasdaman 8 service.

Some queries that return a result in rasdaman 8 are returning an error in rasdaman 9. The queries are all within the bounds of the coverage.

For example:

OLD (rasdaman 8) service query returns a black (area of no data) image with:

for v1 in (pga_cir) return
    encode(
        scale(
            trim(struct {red : (char) v1.red; green : (char) v1.green; blue : (char) v1.blue},
            {x:"http://www.opengis.net/def/crs/EPSG/0/27700"(262260:264575), 
             y:"http://www.opengis.net/def/crs/EPSG/0/27700"(720474:722657)}),
            {x:"CRS:1"(0:599), y:"CRS:1"(0:553)},
            {}
            ),
       "png"
    )

NEW (rasdaman 9) service query returns an error with:

for v1 in (pga_cir) return
    encode(
        scale(
            trim(struct {red : (char) v1.red; green : (char) v1.green; blue : (char) v1.blue},
            {E:"http://www.opengis.net/def/crs/EPSG/0/27700"(262260:264575), 
             N:"http://www.opengis.net/def/crs/EPSG/0/27700"(720474:722657)}),
            {E:"CRS:1"(0:599), N:"CRS:1"(0:553)},
            {}
        ),
       "png"
   )

ERROR is:

<ows:ExceptionReport version="2.0.0" xsd:schemaLocation="http://www.opengis.net/ows/2.0 http://schemas.opengis.net/ows/2.0/owsExceptionReport.xsd" xmlns:ows="http://www.opengis.net/ows/2.0" xmlns:xsd="http://www.w3.org/2001/XMLSchema-instance" xmlns:xlink="http://www.w3.org/1999/xlink">

   </ows:ExceptionText>
  </ows:Exception>
</ows:ExceptionReport>

Similarly

OLD (rasdaman 8) service query returns an image with:

for v1 in (pga_cir) return
    encode(
	scale(
	    trim(struct {red : (char) v1.red; green : (char) v1.green; blue : (char) v1.blue},
	    {x:"http://www.opengis.net/def/crs/EPSG/0/27700"(230000:231000), 
             y:"http://www.opengis.net/def/crs/EPSG/0/27700"(710000:711000)}),
	    {x:"CRS:1"(0:481), y:"CRS:1"(0:499)},
	    {}
	),
	"png"
    )

But NEW (rasdaman 9) service query returns an error with:

for v1 in (pga_cir) return
    encode(
	scale(
	    trim(struct {red : (char) v1.red; green : (char) v1.green; blue : (char) v1.blue},
	    {E:"http://www.opengis.net/def/crs/EPSG/0/27700"(230000:231000), 
             N:"http://www.opengis.net/def/crs/EPSG/0/27700"(710000:711000)}),
	    {E:"CRS:1"(0:481), N:"CRS:1"(0:499)},
	    {}
	),
	"png"
    )

See the below dump from catalina.out for this above error.

I don't always get errors though:

OLD service request returns image ~ a mix of aerial photo and no data (black):

for v1 in (pga_cir) return
    encode(
        scale(
	    trim(struct {red : (char) v1.red; green : (char) v1.green; blue : (char) v1.blue},
	    {x:"http://www.opengis.net/def/crs/EPSG/0/27700"(209208:211662), 
             y:"http://www.opengis.net/def/crs/EPSG/0/27700"(707380:709649)}),
	    {x:"CRS:1"(0:599), y:"CRS:1"(0:553)},
	    {}
	),
	"png"
    )

NEW service request returns image ~ a mix of aerial photo and no data (white):

for v1 in (pga_cir) return
    encode(
	scale(
	    trim(struct {red : (char) v1.red; green : (char) v1.green; blue : (char) v1.blue},
	    {E:"http://www.opengis.net/def/crs/EPSG/0/27700"(209208:211662), 
             N:"http://www.opengis.net/def/crs/EPSG/0/27700"(707380:709649)}),
	    {E:"CRS:1"(0:599), N:"CRS:1"(0:553)},
	    {}
	    ),
	"png"
    )

And finally OLD and NEW service return the same image.

OLD:

for v1 in (pga_cir) return
    encode(
        scale(
	    trim(struct {red : (char) v1.red; green : (char) v1.green; blue : (char) v1.blue},
	    {x:"http://www.opengis.net/def/crs/EPSG/0/27700"(440000:441000), 
             y:"http://www.opengis.net/def/crs/EPSG/0/27700"(500000:501000)}),
	    {x:"CRS:1"(0:481), y:"CRS:1"(0:499)},
	    {}
	),
	"png"
    )

NEW:

for v1 in (pga_cir) return
    encode(
        scale(
	    trim(struct {red : (char) v1.red; green : (char) v1.green; blue : (char) v1.blue},
	    {E:"http://www.opengis.net/def/crs/EPSG/0/27700"(440000:441000), 
             N:"http://www.opengis.net/def/crs/EPSG/0/27700"(500000:501000)}),
	    {E:"CRS:1"(0:481), N:"CRS:1"(0:499)},
	    {}
	),
	"png"
    )

Hi James,

thanks for the comprehensive report.

Regarding the transparency and black/white differences, I know there is some (currently unilateral) discussion going on, thanks to the (great) post by Marcus.

Regarding the error: I cannot reproduce it… I can successfully run:

for v1 in (rgb) return
encode( scale(
    trim(struct {red : (char) v1.red; green : (char) v1.green; blue : (char) v1.blue},
      {i:"http://localhost:8090/def/crs/OGC/0/Index2D"(0:100), 
       j:"http://localhost:8090/def/crs/OGC/0/Index2D"(0:200)}), 
    {i:"CRS:1"(0:300),
     j:"CRS:1"(0:600)}, {})
, "png"

Which kind of coverage is pga_cir ?

comment:3 by James Passmore, 11 years ago

The pga_cir coverage is a digital orthophoto colour infra-red aerial photography mosaic, covering most of the UK.

DescribeCoverage output for the pga_cir coverage (NEW SERVICE) is below:

The coverage was loaded as a series of small image tiles (1 sq km) using rasimport. The image tiles do not cover the whole domain.

holes in the pga-cir coverage

comment:5 by James Passmore, 11 years ago

Looking at the comparable WCS requests for the same extents causing an error in rasdaman 9 WCPS query…

OLD service gives an image:

http://.../petascope?service=WCS&Request=GetCoverage&version=2.0.0&CoverageId=pga_cir&format=image/tiff&subset=x(230000,231000)&subset=y(710000,711000)&

NEW service gives an error:

http://.../rasdaman/ows?service=WCS&Request=GetCoverage&version=2.0.1&CoverageId=pga_cir&format=image/tiff&subset=E(230000,231000)&subset=N(710000,711000)&

    Error converting WCPS query to rasql query: Invalid coverage Expression, next node: trim - Unknown node for TrimCoverage expression: trim[Invalid coverage Expression, next node: trim - Invalid cell domain element: lower bound -60000 cannot be larger than upper bound -58000]
    </ows:ExceptionText>
  </ows:Exception>

Which is an odd error because -60000 is not larger than -58000 in a CRS

Hi James,
that's bad.. you are probably hit by the bad critical bug #686, whose fix is included in v9.0.1. Are you running v9.0.0?

comment:7 by Marcus Sen, 11 years ago

We are indeed using v9.0.0 so we'll try v9.0.1. (I had thought the v9.0.1 fixes were just to do with upgrading from older v8 installations).

comment:8 by Marcus Sen, 11 years ago

I confirm that upgrading to v9.0.1 has fixed the errors in the queries above. So this ticket can be closed. (The 0,0,0 pixels appearing white instead of black seems to be the separate issue #741 of v9+ always setting these to transparent rather than using any explicit nodata parameter set in the WCPS query. That's not a problem in this case.)
