Assorted Raster Format Problems
-------------------------------
Key: UDIG-1469
URL: http://jira.codehaus.org/browse/UDIG-1469
Project: uDIG
Issue Type: Bug
Components: image
Affects Versions: UDIG 1.2.M0
Environment: Win XP Pro
Reporter: Jody Garnett
Assignee: Jesse Eichar
The following bug report has been provided to me (see the attached XL file for
the complete breakdown with screen snaps). The gist of this bug report is that
several images that displayed correctly in uDig 1.1 now fail to renderer in
uDig 1.2.

QuickBird/Pan
- uDig 1.1: Image Opens in 30 seconds
- uDig 1.2: Projection displayed but Image not loaded even after paning or
zooming
http://www.digitalglobe.com/index.php/70/Product+Samples/Boulder_Standard_Multi_16bit.zip
QuickBird/MSS
- uDig 1.1: Image Opens in 30sec. The Image is displayed in Gray scale with
green patches in few places
- uDig 1.2: Projection displayed but Image not loaded even after paning or
zooming

IKONOS/Pan
- uDig 1.1: Image Opens in 2 Min
- uDig 1.2: Projection displayed but Image not loaded even after paning or
zooming
IKONOS/MSS
- uDig 1.1: Image Opens in 5 min with message "Rendering an error occurred
when drawing try zooming closer to panning to another part of the image". Image
was not displayed in Fit screen mode but it dsplayed after panning and zooming
- uDig 1.2: Projection displayed but Image not loaded even after paning or
zooming

IRS/Liss3
- uDig 1.1: Image does not open with error 'rendering null'
- uDig 1.2: Image not loaded, no change in projection either. Gives an error
message like 'Co-ordinate Reference System of data is unknown'

ALOS/Prism
- uDig 1.1: Image was first converted to geoTif and then it opened in 50sec
- uDig 1.2: Image not loaded, the format is not supported at all by UDIG. Even
after converting to .tif the image did not display, gave an error message like
'Co-ordinate Reference System of data is unknown'

ALOS/AVINIR2
- uDig 1.1: Image was first converted to geoTif and then it opened in 40sec
- uDig 1.2: Image not loaded, the format is not supported at all by UDIG. Even
after converting to .tif the image did not display, gave an error message like
'Co-ordinate Reference System of data is unknown'
http://www.geoeye.com/CorpSite/resource/sample_imagery.aspx
OrbView/Pan
- uDig 1.1: Image was first converted to geoTif and then it opened in 1 min.
The no feature are discernable on the image.
- uDig 1.2: Neither .tif nor .jpg is opening even though both the formats are
supported. No error message displayed in case of error
OrbView/MSS
- uDig 1.1: Image was first converted to geoTif and then it opened in 50 sec.
The image opened in gray scale
- uDig 1.2: Neither .tif nor .jpg is opening even though both the formats are
supported. No error message displayed in case of error
General Comments on this Issue:
* Since we do not know how they converted the images much of the information
provided is not going to help us :-(
* We have a new raster library at work here in uDig 1.2 and thus we should
expect differences. Also the SLD support for RasterSymbolizer now functions (so
we may be seeing the work of a poorly chosen default RasterSymbolizer.
* The long load times (and some time failures) seen in uDig 1.1 are probably
doing to loading an image into memory - and in the case of failures running out
of memory. As a result it would be nice to check the log and see if any out of
memory messages occured.
