Sorry,It seems that noone of the Gdal maillist is in line,and the grass itself call some gdal commond,so I post the message here. ---------- Forwarded message ---------- From: maven apache <apachemav...@gmail.com> Date: 2009/9/15 Subject: how to handle the hdf4 using gdal To: gdal-...@lists.osgeo.org
Hi : I want to handle some hdf4 data using gdal,and my goal is to get the subdatasetname of one hdf4,and I know I can use the gdalinfo to get the information,however what I get is just some plain text format as follows: ------------------------- WESTBOUNDINGCOORDINATE=94.0216705976118 NORTHBOUNDINGCOORDINATE=58.2075179501186 EASTBOUNDINGCOORDINATE=131.825225491885 SOUTHBOUNDINGCOORDINATE=36.448663754723 PROCESSINGENVIRONMENT=Linux minion5141 2.6.8.1-25mdksmp #1 SMP Tue May 31 09:52:06 MDT 2005 i686 IntelR PentiumR III CPU family 1133MHz unknown GNU/Linux DESCRREVISION=5.0 Subdatasets: SUBDATASET_1_NAME=HDF4_EOS:EOS_SWATH:"D:\data\HDF\MYD29.A2009061.0520.005.2009062044632.hdf":MOD_Swath_Sea_Ice:Sea_Ice_by_Reflectance SUBDATASET_1_DESC=[2030x1354] Sea_Ice_by_Reflectance MOD_Swath_Sea_Ice (8-bit unsigned integer) SUBDATASET_2_NAME=HDF4_EOS:EOS_SWATH:"D:\data\HDF\MYD29.A2009061.0520.005.2009062044632.hdf":MOD_Swath_Sea_Ice:Sea_Ice_by_Reflectance_Pixel_QA SUBDATASET_2_DESC=[2030x1354] Sea_Ice_by_Reflectance_Pixel_QA MOD_Swath_Sea_Ice (8-bit unsigned integer) SUBDATASET_3_NAME=HDF4_EOS:EOS_SWATH:"D:\data\HDF\MYD29.A2009061.0520.005.2009062044632.hdf":MOD_Swath_Sea_Ice:Ice_Surface_Temperature SUBDATASET_3_DESC=[2030x1354] Ice_Surface_Temperature MOD_Swath_Sea_Ice (16-bit unsigned integer) SUBDATASET_4_NAME=HDF4_EOS:EOS_SWATH:"D:\data\HDF\MYD29.A2009061.0520.005.2009062044632.hdf":MOD_Swath_Sea_Ice:Ice_Surface_Temperature_Pixel_QA SUBDATASET_4_DESC=[2030x1354] Ice_Surface_Temperature_Pixel_QA MOD_Swath_Sea_Ice (8-bit unsigned integer) ------------------------------------------------------------------------------- So if I want to extract the subdataset name I should parser the text by myself, I wonder if there are some liberary can do it using its method(maybe like this [getSubDataSetArrry()]). BTW,I am using java,and I want to know how to install the gdal in the xp os? Since I am using the gdal included in FWTools2.2.8,so I have to install the FWTTools frist,I wonder if there is other easy way?
