osgdem转换后影像被切割掉一部分

lucyli

要做的工作是将tif格式用vbp转换为ive格式，读取到osgearth中去，现在碰到的问题是：直接使用osgdem转换（代码为osgdem -t jilinshi_1.tif --geocentric --terrain -o jilin.ive）,生成的jilin.ive加载到osgearth中，图片被切割了右边一部分。。。
        如果在osgdem中没有加入--geocentric选项，则生成的jilin.ive正常，没有被切割，但无法载入osgeargth中（应该是坐标系问题）。
        然后我用gdalinfo查看了jinlinshi_1.tif，显示如下：

使用的应该是Gauss Kruger投影坐标系，应该要转换成地球地心坐标系（地理坐标系）才能集成到osgearth中。
然后我考虑使用gdalwrap进行转换，
E:\osgearthlearning>gdalwarp -t_srs WGS84 jilinshi_1.tif jilin.tif
Processing input file jilinshi_1.tif.
ERROR 1: Too many points (441 out of 441) failed to transform,
unable to compute output bounds.

不能正常转换，各位高手帮忙看看，怎么解决，
