Description (last modified by )
I have the following compressed Heightfield raster that was originally generated by gdal_translate
(see attached test.hfz
file):
$ gdalinfo -stats test.hfz Driver: HF2/HF2/HFZ heightfield raster Files: test.hfz Size is 257, 257 Coordinate System is: PROJCS["WGS 84 / Pseudo-Mercator", GEOGCS["WGS 84", DATUM["WGS_1984", SPHEROID["WGS 84",6378137,298.257223563, AUTHORITY["EPSG","7030"]], AUTHORITY["EPSG","6326"]], PRIMEM["Greenwich",0, AUTHORITY["EPSG","8901"]], UNIT["degree",0.0174532925199433, AUTHORITY["EPSG","9122"]], AUTHORITY["EPSG","4326"]], PROJECTION["Mercator_1SP"], PARAMETER["central_meridian",0], PARAMETER["scale_factor",1], PARAMETER["false_easting",0], PARAMETER["false_northing",0], UNIT["metre",1, AUTHORITY["EPSG","9001"]], AXIS["X",EAST], AXIS["Y",NORTH], EXTENSION["PROJ4","+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +wktext +no_defs"], AUTHORITY["EPSG","3857"]] Origin = (777823.199999999953434,5845904.000000000000000) Pixel Size = (19.034903000000185,-19.034903000000185) Metadata: VERTICAL_PRECISION=1.000000 Corner Coordinates: Upper Left ( 777823.200, 5845904.000) ( 6d59'14.30"E, 46d24'27.23"N) Lower Left ( 777823.200, 5841012.030) ( 6d59'14.30"E, 46d22'38.12"N) Upper Right ( 782715.170, 5845904.000) ( 7d 1'52.50"E, 46d24'27.23"N) Lower Right ( 782715.170, 5841012.030) ( 7d 1'52.50"E, 46d22'38.12"N) Center ( 780269.185, 5843458.015) ( 7d 0'33.40"E, 46d23'32.68"N) Band 1 Block=256x1 Type=Float32, ColorInterp=Undefined ERROR 3: File too short ERROR 1: test.hfz, band 1: IReadBlock failed at X offset 0, Y offset 0 ERROR 3: File too short ERROR 1: test.hfz, band 1: IReadBlock failed at X offset 0, Y offset 1 Minimum=0.000, Maximum=2184.915, Mean=1662.401, StdDev=227.929 Unit Type: m Metadata: STATISTICS_MAXIMUM=2184.9145507812 STATISTICS_MEAN=1662.4009253152 STATISTICS_MINIMUM=0 STATISTICS_STDDEV=227.9285753811
As you can see gdalinfo
outputs errors, but still exits successfully with status 0
. Running the same file through gdal_translate
does fail with exit status 1
, however:
$ gdal_translate -of GTiff test.hfz test.tiff Input file size is 257, 257 0ERROR 3: File too short ERROR 1: test.hfz, band 1: IReadBlock failed at X offset 0, Y offset 0 ERROR 1: GetBlockRef failed at X block offset 0, Y block offset 0
test.hfz
appears to be valid and can be displayed correctly by the official L3DT client, as well as QGIS:
