Hi:<br>I have some hdf5 data and I want to change the subdataset to geotiff, and I use gdalinfo to get the subdataset name and then I use "gdal_translate subdatasetname result.tif".<br>However I found that the crs of the generated tif is not recognized by the arcgis,then I want to know why so I create a new tif by arcgis(here it is named arcgis.tif,and the coordinate system is wgs84). Then I use gdalinfo command to get the metadata of the arcgis.tif and compare it with the tif generated by gdal(here I call it gdal.tif). Then I found that the Coordinate are the same as the following:<br>
--------------------------<br>Coordinate System is:<br>GEOGCS["WGS 84",<br> DATUM["WGS_1984",<br> SPHEROID["WGS 84",6378137,298.2572235630016,<br> AUTHORITY["EPSG","7030"]],<br>
AUTHORITY["EPSG","6326"]],<br> PRIMEM["Greenwich",0],<br> UNIT["degree",0.0174532925199433],<br> AUTHORITY["EPSG","4326"]]<br>------------------------------<br>
the difference is the <b>Corner Coordinates</b>:<br>the arcgis.tif is :<br>-------------------<br>Corner Coordinates:<br>Upper Left ( 103.8438587, 28.6769083) (103d50'37.89"E, 28d40'36.87"N)<br>Lower Left ( 103.8438587, 28.6668077) (103d50'37.89"E, 28d40'0.51"N)<br>
Upper Right ( 103.8546032, 28.6769083) (103d51'16.57"E, 28d40'36.87"N)<br>Lower Right ( 103.8546032, 28.6668077) (103d51'16.57"E, 28d40'0.51"N)<br>Center ( 103.8492310, 28.6718580) (103d50'57.23"E, 28d40'18.69"N)<br>
------------------<br>the gdal.tif is :<br>----------------<br>Corner Coordinates:<br>Upper Left ( 0.0, 0.0)<br>Lower Left ( 0.0, 720.0)<br>Upper Right ( 1440.0, 0.0)<br>Lower Right ( 1440.0, 720.0)<br>Center ( 720.0, 360.0)<br>
------------------------<br>It seems that the bbox is defined by different manner , the arcgis.tif is by <span id="result_box" class="short_text"><span style="background-color: rgb(255, 255, 255);" title="¶È·ÖÃë">Degrees minutes and seconds and the gdal.tif is by grid of some other?<br>
<br>I wonder how to solve this problem?<br></span></span>
