OpenEV2 news

Hi folks,
Yes, there are still news about OpenEV2 :) I am happy to report that OpenEV2 (and even OpenEV1) will work with GDAL's ng-python, with only minor changes to the code. I still need to test with the just released GDAL 1.6.0 and if all goes well, there will be a major wave of commits next weekend in preparation for a package release. cheers -- Mario B. ------------------------------------------------------------------------------ SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.

Hi Mario,
Do you think it will be possible to allow OpenEV2 to use the GDAL GeoRaster driver? I can make OpenEV load a GeoRaster object through the help of a VRT file. Like that: % gdal_translate -of VRT geor:usr/pwd@db,rdt,1 view.vrt % openev view.vrt But if I enter the connection string i.e. "geor:usr/pwd@db,rdt,1" on the FileSelectionBox or in the command line it complain that that "file" does not exist. % openev "geor:usr/pwd@db,rdt,1" Let me know what you think about it and if there is something that I can do to help.

Let me investigate and I will get back to you. BTW, does this mean that you actually are using OpenEV2? If so, your experience would be valuable... cheers -- Mario B. ------------------------------------------------------------------------------ SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.

The GeoRaster driver is intended to connect to a Oracle DBMS server to load and extract raster images through GDAL API and command line tools [1]. A GeoRaster dataset is identified by a connection string that resembles a little bit how OGR make connections to DBMS.

I must admit that CIETmap uses almost exclusively the GeoTiff driver so I didn't spend a lot of time checking to see if every GDAL supported formats work in OpenEV. This is something I hope the community will do once a working OpenEV2 is available ;) Also, still being on dialup, access to data in various formats is difficult... > The GeoRaster driver is intended to connect to a Oracle DBMS server to load > and extract raster images through GDAL API and command line tools [1]. > > A GeoRaster dataset is identified by a connection string that resembles a > little bit how OGR make connections to DBMS. Not having access to that kind of resource, it is difficult for me to test anything. Do you think you could provide that? And it would have to be a (very) small image ;) Also, my knowledge of DBMS is close to nil... so bear with me! cheers -- Mario B. ------------------------------------------------------------------------------ SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.

Hi Mario,
In fact you don't need particular knowledge of the GeoRaster driver or DBMS. I think Ivan's point was that currently OpenEV requires in its open dialog box that the string that the user enters is a filename relative to the current working directory, whereas GDALOpen and OGROpen can accept arbitrary strings. Most drivers will interpret those strings as filenames, but others will have their own parsing of the string to open the right connexion to the database. For example, "openev http://download.osgeo.org/gdal/data/gtiff/small_world.tif" works on the command line (it is recognized by the GDAL HTTP driver), but if you enter http://download.osgeo.org/gdal/data/gtiff/small_world.tif in the open dialog box, you get "ERROR: Unable to open /home/even/http://download.osgeo.org/gdal/data/gtiff/small_world.tif" So the opening sequence could be : - try opening "current_path/name_entered_in_the_entry_box" - if it fails, try opening "name_entered_in_the_entry_box" Best regards.

The only idea I got is: does this work if you do this in a Python shell: ds = gdal.Open("geor:usr/pwd@db,rdt,1") if you have a ds and no error, there is hope OpenEV2 will be able to do that... but I will spare you the details ;) Unfortunately, I found new problems with the GDAL ng-python integration so this will delay things a bit :( cheers -- Mario B. ------------------------------------------------------------------------------ SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.
