Everyone<br>
<br>
I am working on integration of Raster data into the Django
web-framework leveraging GDAL. For this I have written some GDAL
C-Bindings through ctypes in python.</font><br>
<font size="-1"><font size="-1"><font size="-1"><br>

<br>
For reading and storing data to a database, I would like to add
the possibility to convert a raster into a WKB format. For
geometries, GDAL has the "</font><font size="-1">OGR_G_ExportToWkb"
function for OGR:<br>

</font></font><br>
<font size="-1"><font size="-1"><font size="-1">However, If I am
not mistaken there is nothing similar for rasters. </font></font>I
have written function that converts a raster into a PostGIS
Raster WKB buffer in python, but I am not sure if this is the
best approach:<br>
<br>

<br>
So my questions are the following:</font><br>
<br>
<font size="-1"><font size="-1">Is the inclusion of WKB raster
export/import part of the GDAL Roadmap?<br>
<br>
</font>Do you know any other WKB representation for raster data
other than PostGIS Raster?<br>
<br>
If yes, which WKB format would you find most appropriate here?<br>
<br>
Do you happen to know where PostGIS Raster is documented? I
understand how it is constructed, but I had to piece it together
from the source code and the user documentattion.<br>

Thank you in advance for your help,<br>
