ArcGrid ASCII format malfunction (AsciiGridsImageMetadata malfunction)
----------------------------------------------------------------------
Key: GEOT-1781
URL: http://jira.codehaus.org/browse/GEOT-1781
Project: GeoTools
Issue Type: Bug
Components: gc arcgrid
Affects Versions: 2.4.2
Environment: Windows XP
Reporter: Jong Lee
Assignee: Simone Giannecchini
ArcGrid Ascii file generated by ArcGridWriter uses wrong format as below:
XLLCENTER xxx.xxx
YLLCENTER xx.xxx
it should be:
XLLCORNER xxx.xxx
YLLCORNER xx.xxx
I found that it occurs becuase of AsciiGridsImageMetadata class in
imageio-ext-arcgrid.
At line 357-359, in ArcGridWriter.java, it creates AsciiGridsImageMetadata
object by using (isCorner = true) parameter. It should create:
XLLCORNER xxx.xxx
YLLCORNER xx.xxx
but it uses XLLCENTER & YLLCENTER instead. I tested with (isCorner = false),
it creates XLLCORNER and XLLCORNER.
So, AsciiGridsImageMetadata needs to be fixed for this behavior.
