Re: [Qgis-user] Mosaicking aerial images
Hi Andreas, I'm Bringing this back to the list, as others here probably have some better thoughts than I do. Googling around, I found this tool which might be useful (?), though I can't tell how it handles overlaps [haven't even downloaded it...]: https://trac.osgeo.org/gdal/wiki/Correlator Not sure about enblend (can't access the site right now) Depending on how different the images are, you could just try mosaicing and see what it looks like (gdal_merge takes the values of last image added for overlaps). If there's a way to standardize color values based on brightness, or by RGB bands, that might help, either before or after mosaicing. (might depend on if you're dealing with multi-band image, or single band? - it would be fairly easy on multi-band like Landsat) Hope that helps, mike On Wed, Dec 10, 2014 at 9:28 AM, Andreas Neumann a.neum...@carto.net wrote: Hi Michael, I have 4 images with approx 30% overlap in each axis (north/east).

Re: [Qgis-user] Mosaicking aerial images
Hi, The correlator project sort of does what I need, however, probably without blending/fusing. On the other hand my images are already very well georeferenced (with thin-plate spline and around 1000 points per image) - so not really a need to correlate. So I am actually more looking for a blending/fusing app that keeps georeferencing. I will probably ask at the gdal list as well to see if someone has an idea. For my panoramic photography I use either hugin or autopano giga. Both do an excellent job with blending, but I fear they would delete my georeferencing data and I don't know if they can handle the big files I have.

Re: [Qgis-user] Trouble parsing the getcapability response.
Richard, really thx to you. Your sample help me to find the solution. Just for other user I share my experience: Starting from the ample of Richard the solution was to pass from version=1.3.0 to version=1.1.1. Infact: Using the version=1.1.1 the root tag is WMT_MS_Capabilities version=1.1.1 And the xpath /WMT_MS_Capabilites/Service/Name work perfectly. Instead firstly I try using the version=1.3.0. That mean a root tag like this: WMS_Capabilities version=1.3.0 xsi:schemaLocation=http://www.opengis.net/wms http://qgis.org/wms_1_3_0.xsd; I dont knw why, but with this root tag the xpath /WMS_MS_Capabilites/Service/Name dont work.

Re: [Qgis-user] Mosaicking aerial images
Hi Andreas, I wrote a QGIS python plugin a number of years ago for merging overlapping imagery, it can be found at: http://www.mappinggeek.ca/QGISPythonPlugins/ under the title Image Clipper. I developed it for my day job where our map/photo sales people wanted to georeferenced and merge aerial photography for map photo bases. Our staff continue to use this plugin to merge georeferenced photography. This plugin has never been upgraded to QGIS version 2, at some point I would like to tackle that but I haven't done any python development in QGIS for a couple of years so I'm leery of that. You might want to investigate OSSIM as I believe that it has tools for merging and colour balancing of overlapping images.

Re: [Qgis-user] py2exe for windows, import qgis.core anf qgis.gui
Hey Robert, It can be done. I have done it with my Roam project, you can find the setup.py logic here https://github.com/DMS-Aus/Roam/blob/master/setup.py The three main things are: 1) Make sure you have a batch file that does path setup and call it before running: python setup.py py2exe. You can see an example at https://github.com/DMS-Aus/Roam/blob/master/scripts/setenv.bat I run this is all my sub scripts when building, etc. Basically call setenv.bat call python setup.py py2exe 2) You need to copy things like qgis provider plugins and resources into the package, you can see that being done here: https://github.com/DMS-Aus/Roam/blob/master/setup.py#L82 (ignore the mess there) 3) You will need to do some path setup before you call QgsApplication or else things will not load correctly: https://github.com/DMS-Aus/Roam/blob/master/src/roam/environ.py#L107 The Roam code might not be a good example as there is a lot of other things in there but you should be able to make your way though it to work it out. - Nathan On Thu Dec 11 2014 at 12:34:47 AM kissa hiri kissa.h...@gmx.at wrote: dear community!
