[Qgis-user] Simulation of dam failure & mapping of flood risk downstream
Good afternoon, I have to simulate an artificial dam failure & mapping of flood risk downstream. I have already generate watershed file thanks to r.watershed. Now i want to mapping and calculate flood risk downstream (water level / volume /cubature) from a few available informations like charge,flow,etc. Could you throw light for me please? If you know other tools and algorithms that can help me in my study, don't hesitate. Thank you in advance.

[Qgis-user] How to Compile GDAL from gdal trunk and qgis from source ?
Hello, I have posted a message there a few weeks. I asked you a way to compile the "last Gdal version from trunk" and Qgis from source targeting your gdal source as library in order to use the last Gdal postis raster driver. You answered that the last binairies qgis 1.8 version is available with the last version of gdal (1.9.1) and that it's useless to compile. I understand your reply. BUT I have talked last days with developpers of "Gdal Postgis raster driver". They just add several important updates to the driver. And they confirm to me that the only way to use the last driver is to compile GDAL from gdal trunk and qgis from source using that compilation as GDAL version. Please to read below few sentences written by those developpers : -- That's the only way to get the development version working. You have to compile GDAL from svn and qgis from source using that compilation as GDAL version. I'm not following osgeo4w binaries, but I don't think they would provide a QGIS build with both gdal and qgis from svn. It's not entirely impossible because I know they release a few nightly snapshots. So, you have to use the last GDAL version from trunk in order to have the last "Gdal Postgis raster driver updates".You just need to compile QGIS from source targeting your GDAL source as library.I think that if you make any header changes you may need to recompile it all since QGIS depends on GDAL.So you have to work with last gdal version from trunk. -- I need this last version of Gdal Postgis raster driver on my windows 7-64 bits station but those developpers working on Linux. Could you explain to me the way to compile GDAL from gdal trunk and qgis from source using that compilation as GDAL version (sources links to download, compilation procédure,etc.). I am a thematician geograph and i am a novice in software compilation;-( In advance, thank you for your reply. Kind regards.

[Qgis-user] Postgis raster display plugin ("Load Postgis Raster Layer") : slowness
Hello,
I'm trying to display "Raster postgis data" via Qgis ("Load Postgis Raster
Layer"). It works but it's a bit slow!
These raster are 11 Rapideye satellite images with 5 bands in native. I
defined following overviews for each data : 3,9,27,81,243
Size of smallest SQL file : 270 MO
Size of biggest SQL file : 679 MO
1/What do you think about overviews values ?
2/According to you, the plugin is abble to display a sql file with a size of
679 MO ?
3/In native, these data have 5 bands but we need display only 3 bands.
According to you, is it better before importing these data in database to
remove 2 useless bands in order to speed up the display ?
4/Is there update regarding the speed problem ( Gdal driver issue).
5/Is there another way faster (Gvsig for instance) in displaying postgis
raster data?
Thank you to throw light for me.
Regards.
Laurent Celati.
