Many thanks for your answers!!!
Now I am developing a library that handles TIFF and geoTIFF, but I have
noted that I need to include RPCCoefficientTag to the TIFF file. Searching
on the internet I have found that this tag is not suported by geoTIFF spec
1.0, it is only suported by gdal. Is this

Hi all,
Is there an executable utility that takes the corner coordinates from a gtiff
and translates them into another projection system? For example, I have a
gtiff in UTM and I want to translate the coordinates of the bounding box (or
corners) into WGS84. Or is there a way to do this
Jon,
gdaltransform does some of this. It looks to do 4 corners you would
need to do it four times or list the coordinate pairs on four lines and get
four lines of output back. There might be a clever way to take the output of
gdalinfo as input into gdaltransform saving you some
Many Thanks Frank, I have insert the RPCCoeffcientTag to the file.
Is any comercial software that could read this TAG? In order to
check the implementation I need open the file with a comercial software. I
have tried with ENVI but it does not recognize the format.
Best Regards,

I want to overwrite a shapefile using ogr(c++). If the dbf file in the
destination shapefile is already open by anather program(exel), the
operation fails in the middle and only the shp and shx files are updated.
How could I check, using OGR, if the dbf(or any other file in the shapefile)
I have a script, written to use ESRI's ArcPy, which I am attempting to
re-write using the ogr/gdal python bindings. One of the parameters that I
can pass to ESRI's MakeFeatureLayer function is an SQL Query. This creates
a featurelayer (in memory) which contains only those rows which meet the
Hi, Thanks for the reply.
When I tried this first, the image was displaying just black and white. But
after some experimentation I discovered that '-ot Byte' with gdal_rasterize
gave polygons colored various shades of grey - though not related to my
attribute - seemed to be random.
I dont

1. First, make sure the attribute value field contains a single value for
each color, starting from one.
2. Run gdal_rasterize after adding the option '-init 0' to your original
options. This option makes sure that the background pixels are initialized
to zero. You will get a

You can do all the stuff using OGR's SQL engine. OGR also supports memory
layers.
Refer to GDAL's RFC 28 [1], and the test scripts [2] [3]

Ramiro,
You can use the OGRLayer::TestCapability() method to check write capability
of a layer. However, there are going to be errors if another process
accesses the files in the mean while.
When ogr2ogr is executed with -append, -overwrite or --update options, it
should error out with the
