Hi list.
I'm trying to learn raster handling with geotools and Java.
I've been looking at the example code "Image Tiling Application"
https://docs.geotools.org/latest/userguide/tutorial/coverage/coverage.html
I have a file:
Size is 8123, 12480
Coordinate System is:
GEOGCRS["WGS 84",
DATUM["World Geodetic System 1984",
ELLIPSOID["WGS 84",6378137,298.257223563,
LENGTHUNIT["metre",1]]],
PRIMEM["Greenwich",0,
ANGLEUNIT["degree",0.0174532925199433]],
CS[ellipsoidal,2],
AXIS["geodetic latitude (Lat)",north,
ORDER[1],
ANGLEUNIT["degree",0.0174532925199433]],
AXIS["geodetic longitude (Lon)",east,
ORDER[2],
ANGLEUNIT["degree",0.0174532925199433]],
ID["EPSG",4326]]
Data axis to CRS axis mapping: 2,1
Origin = (15.373676860688539,64.534556346504218)
Pixel Size = (0.000419878389258,-0.000187830401707)
Metadata:
AREA_OR_POINT=Area
TIFFTAG_RESOLUTIONUNIT=2 (pixels/inch)
TIFFTAG_XRESOLUTION=300
TIFFTAG_YRESOLUTION=300
Image Structure Metadata:
COMPRESSION=LZW
INTERLEAVE=PIXEL
Corner Coordinates:
Upper Left ( 15.3736769, 64.5345563) ( 15d22'25.24"E, 64d32' 4.40"N)
Lower Left ( 15.3736769, 62.1904329) ( 15d22'25.24"E, 62d11'25.56"N)
Upper Right ( 18.7843490, 64.5345563) ( 18d47' 3.66"E, 64d32' 4.40"N)
Lower Right ( 18.7843490, 62.1904329) ( 18d47' 3.66"E, 62d11'25.56"N)
Center ( 17.0790129, 63.3624946) ( 17d 4'44.45"E, 63d21'44.98"N)
Band 1 Block=8123x130 Type=Byte, ColorInterp=Red
NoData Value=255
Band 2 Block=8123x130 Type=Byte, ColorInterp=Green
NoData Value=255
Band 3 Block=8123x130 Type=Byte, ColorInterp=Blue
NoData Value=255
When I try to split the file in 2x2 tiles, there is no problem, but when I try
to split it in 10x10 tiles I get the following printout and exception (Scale
=1):
Processing tile at indices i: 0 and j: 0
Processing tile at indices i: 0 and j: 1
Processing tile at indices i: 0 and j: 2
Processing tile at indices i: 0 and j: 3
Processing tile at indices i: 0 and j: 4
Processing tile at indices i: 0 and j: 5
Processing tile at indices i: 0 and j: 6
Processing tile at indices i: 0 and j: 7
Processing tile at indices i: 0 and j: 8
Processing tile at indices i: 0 and j: 9

Can anyone see what I'm doing wrong?
Kind regards,
