[Qgis-user] Problem with European Drought Observatory WCS layer
Dear List, I am trying to add a wcs layer from the European Drought Observatory (EDO [1] ) server, but I am unable to do so. The layer is being reported as invalid(?). I'm not really familiar with wcs layers so I don't know if Im doing something wrong in my part. Maybe someone can cross check if the wcs layer is operational ? The link for "DescribeCoverage" attribute is the following: http://edo.jrc.ec.europa.eu/edov2/php/ows.php?SERVICE=WCS&VERSION=1.1.1&REQUEST=DescribeCoverage&COVERAGE=Combined_Drought_Indicator Thank you, Nick [1] http://edo.jrc.ec.europa.eu/ ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

[Qgis-user] Create monthly images from fixed timely images
Hey all, Sorry for cross emailing in two lists, but I believe the issue is interesting for both users. Is there a method that can create monthly LST images from MOD11a2 ? The problem arises if you consider that MOD11a2 gets released every 8days and you want to create a monthly image combining n*8days accordingly. eg: month1_image: 1st-day + 9th-day + 17th-day + 25th-day + 6/8*33rd-day month2_image: 2/8*33rd-day + 41st-day and so on as you can see it gets quite complicated find the weighting values for first and last input days because as the example shows 33rd-day goes for the first month as well for the 2nd month. Anyone had crossed into this kind of problem before? If so how did you solve it?

[Qgis-user] qgis, gdal and hdf (ubuntu)
For those wondering qgis cant open hdf files, because the Ubuntu repo flavor or gdal isn't compiled with hdf support. You have to compile it yourself and then recompile qgis with your custom build. That made me wondering: Why qgis needs gdal to be defined on compilation time? Isn't possible to use gdal as external lib, and as so being able to 'change the path' through options or something similar - that would be easier (for me) to just point to the version of gdal i like. regards ves nikos ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

Re: [Qgis-user] corine land cover shapefile...
here's a qml with the legent of every class of CORINE according eea's legend file.(attach1) in your shape file, make a new attribute table, and name it(!) CODE_00 (!) and populate it with the codes without any dots. eg class 1.1.1 should become 111 at column CODE_00. This is important: name it CODE_00 otherwise it wont work, and the length should be at least 3 chars long. The reason for this is that the original corine shapefiles already comes with like that. Don't forget to save after making the column. After that load the qml. I haven't applied the official colours but if needed I can take some time to tune it.

I agree, that will take much less time. Contour function for me always takes huge amount of time for me, especially if its complex, like slope.

It's not my plugin, so I wont judge if it needs to be fixed or not. But for as I see, its not a valid bug. What happens if there are two diff polygons of the same attribute? for example, if the user wants A:1/2/3, B:3/4/5, A:6/7/8 instead of A:1/2/3/6/7/8 ( points (1 2 3) and (6 7 8) are far away from each other) An option to be more strict with the topology, so we all be happy, would be nice, no doubt. But for now, what you need is merging two shapes into one, and i almost certain that there's a tool for that -- nikos ves ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

Training areas, to my knowledge, are AOI's (usually polygons) that refer to the same attribute. If you need to make then, then you need to digitize them manually.

Re: [Qgis-user] Passare dei parametri all'apertura del progetto Qgis
If I understood correctly you're trying to add data(objects) from different users that are projected in different projection system. And naturally they don't fit together because one's X is the others Y... If thats the case, Its always better to work in a fixed projection system. Choose one and stay in that projection. If you have data that are using another projection, you can use "Export To another Projection" (Vector->Data managment-> Export To another Projection" and muster all your data in the within one projection. Having said that... QGIS supports "on-the-fly" transformations.In my experience at least, SVN version is a bit buggy at the moment, but some people suggested that if you state from the start your desired projection system, and enable, at that point "on-the-fly" transformation, you will get very results. To summarize: 1) File->New Project (Close without saving),then 2) File->Project Properties... ,3) Coordinate Reference System (CRS), 4) Make sure you check the Enable 'on the fly' CRS tranformation + choose the crs of your love.

One problem I see, is multiple polygones merged in One big messy polygone due to hte fact that it cant "understand" where a polygon ends and the next one starts. If that case arise a little editing comes handy. The whole point as I see it is to minimize doing double work Ofcouse if the plugin is inadequate for the job, the next option is to shape the polygons from, as Mark said, the points mir already has utilizing the snap feature > On Wed, May 12, 2010 at 1:11 PM, mir wrote: > > Hello all, > > > > I have a list of points in sequence that define a polygon.

Help! > > mir > You can use the "Points2One" plugin which makes the task you need. As input takes a point layer and as output gives a polygon or a polyline. In your case you can choose polygon. Be careful with the order of the points, otherwise you might get funny results. eg |1 2| is fine , but |4 3| |1 2| will intersect with itself, making two triangles! |3 4| Ves Nikos ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
[Qgis-user] Qgis + GRASS prefix: Im so anoyed!
Hi list Im s annoyed by this: Im building grass from source, and I install it to a directory inside my /home (to be exact /home//grass7 ) What should i put as grass prefix in ccmake when I compiling qgis? I tried /home//grass7/grass-7.0.svn and /home//grass7/grass-7.0/lib but everytime i get a huge "GRASS NOT FOUND" slap Anyone who made it work that can shed some light?
