Hi all,
I'm new to gdal tools.
I'm trying to transform a JPEG world image to GeoTiff.
My jpeg world map image is cropped to fit on -180.0, -59.1, 180, 90 (minx,
miny, maxx, maxy - EPSG:4326).
Here are the steps:
% gdal_translate -of GTiff -a_srs EPSG:4326 -co "TILED=YES" -co
"JPEG_QUALITY=100" worldmap_hires2.jpg worldmap2.tif
Input file size is 15000, 6225
0...10...20...30...40...50...60...70...80...90...100 - done.
% sudo gdalinfo worldmap2.tif
Driver: GTiff/GeoTIFF
Files: worldmap2.tif
Size is 15000, 6225
Coordinate System is:
GEOGCS["WGS 84",
DATUM["WGS_1984",
SPHEROID["WGS 84",6378137,298.2572235629972,
AUTHORITY["EPSG","7030"]],
AUTHORITY["EPSG","6326"]],
PRIMEM["Greenwich",0],
UNIT["degree",0.0174532925199433],
AUTHORITY["EPSG","4326"]]
Origin = (-180.017964071749986,59.117964071850004)
Pixel Size = (0.035928143500000,-0.035928143700000)
Metadata:
AREA_OR_POINT=Area
Image Structure Metadata:
INTERLEAVE=PIXEL
Corner Coordinates:
Upper Left (-180.0179641, 59.1179641) (180d 1'4.67"W, 59d 7'4.67"N)
Lower Left ( -180.018, -164.535) (180d 1'4.67"W,164d32'5.03"S)
Upper Right ( 358.904, 59.118) (358d54'15.08"E, 59d 7'4.67"N)
Lower Right ( 358.904, -164.535) (358d54'15.08"E,164d32'5.03"S)
Center ( 89.4431122, -52.7083832) ( 89d26'35.20"E, 52d42'30.18"S)
Band 1 Block=256x256 Type=Byte, ColorInterp=Red
Band 2 Block=256x256 Type=Byte, ColorInterp=Green
Band 3 Block=256x256 Type=Byte, ColorInterp=Blue
Corners are not what i want. I would like to obtain -180.0, -59.1, 180, 90
(minx, miny, maxx, maxy).
I'm using ubuntu 9.10 and the package gdal-bin 1.6.3-1
It there any problem with my image? What should I do?
Thanks in advance,
Marco
