SGI driver is tried before SRTMHGT driver in GDALOpen. In SGI Driver's open method, first 2 bytes of the file is compared with 474 and if it passes the file is considered to be an SGI file. Then 4th byte of the file is compared with 1, and if it is not, then an error is created. The problem may be solved, if SRTMHGT driver is tried before SGI driver in GDALOpen (which means SRTMHGT driver will be registered first)." defect closed normal 1.5.2 GDAL_Raster unspecified normal fixed srtm sgi warmerdam
