Like you, I've been manually creating these grids for printing purposes only. It gets painful when I want to display the coordinates in the bottom and right of the grid, having to create several layers... In fact I've been looking for a quick way to add them in various open source gis tools and came up short. So far GRASS is the only that I've seen that allows one to create a such a grid in an easy way (I've tried Qgis, gvSIG, uDIG, OpenJUMP, Kosmo and GRASS). On the downside, with GRASS I have to create a new region and mapset and import my files, which is also time consuming. I am considering learning gmt, mainly to be able to draw these grids on top of my maps... (though I am sure it will be useful for other things as well) So, to conclude, it would be really cool if Qgis had such a feature!

Hi Horst I also like to have the node tools in a pull-down menu. Still I think the separation basic editing toolbar / advanced editing toolbar makes sense because some advanced tools are probably used less frequently, so user should have the possibility to show/hide this toolbar depending on his current task. My suggestion is to hide the advanced editing toolbar by default (for the first start of qgis) such that user interface seems less overcrowded for new users. Also, I'd like to move the split feature tool to the advanced editing toolbar as it probably is used less frequently than 'add feature' and the node tools. What do you think?

AW: [Qgis-user] WFS Support in QGIS ?!
Hi Peter There is WFS support in QGIS with the WFS plugin (plugins - manage plugins - WFS plugin). However, be warned that it has not the same level of maturity as the WMS support. Also, the WFS provider loads everything into virtual memory which might be too much for really big datasets. Regards, Marco -Ursprüngliche Nachricht- Von: qgis-user-boun...@lists.osgeo.org im Auftrag von Peter Willis Gesendet: Di 28.04.2009 19:03 An: qgis-user@lists.osgeo.org Betreff: [Qgis-user] WFS Support in QGIS ?! Hello, I see support for WMS layer import which works reasonably well. I am not seeing WFS feature support, including the attribute data that belongs to the requested feature. WFS support in a GIS is, in some ways, more important than WMS support. This is due to the fact that the GIS can already 'map' things. The point of a GIS is to be able to analyze geographic data based on the assigned attributes given to geographic locales. Being able to use WMS to make pretty pictures is all well and good. The *real* work of GIS has always been in the data analysis. The OGC standards for geographic data interchange (ie: WFS, WMS, SOS, WCS, GML, TML,...etc.) should be the main focus of any aspiring GIS product/application. QGIS programmers can be proud of the fact that they are one of only 4 applications that reasonably support WMS. There are a few non-free applications out there that are supporting WMS very poorly. There are currently *NO applications* that are properly supporting WFS. Although I haven't looked at ESRI products lately. It would be quite a coupe for QGIS to move ahead of the pack by supporting import/export of the majority of the OGC specifications. NOTES: While testing, using a multi-polygon vector with 31478 polygons, each with 3 attributes,I have noticed that **BOTH** Mozilla Thunderbird and M.S Internet Explorer run out of memory while downloading large WFS vector requests in XML format. I downloaded the same vector using 'wget'. The resulting XML file size was a bit larger than 82MB. When developing robust applications for WFS (or any other XML format) it may be wise to anticipate massive files.

Can't we reffer to the reprojected coordinates? Maybe it's something to add to the API? Maybe it is possible with a method that takes the tolerance in pixels, the point where the user clicked and the layer involved. The method then would calculate the search rectangle in layer coordinates.

Many thanks, Micha Hi Micha, To connect PostGIS with ArcGIS products (basic ArcView license and up) you can use zigGIS (http://pub.obtusesoft.com/). This program used to be open source (see http://code.google.com/p/ziggis/ although I've had no luck making it work with 9.2). The developer has since commercialized and revamped the program with a $279 price tag. (In context and ranting in Canadian dollars, ArcView is about $3000, but the minimum license required to connect and edit with an ArcSDE spatial database is ArcEditor, which is about $1. I think ArcInfo is about $2, and ArcSDE is about $15000 not including database software, which ranges from $0 for PostgreSQL to $5000 for MS SQL Server and to $6 for Oracle Spatial). ZigGIS adds some GUI controls to ArcGIS, and it has read/write capabilities. The demo is worth a try, but it only shows a limited number of rows. I don't have a lot of experience with this product, so I can't say too much about any limitations except that it appeared to work fine. To connect PostGIS with Autodesk products (i.e., AutoCAD Map 3D 2008 and up, MapGuide Enterprise or MapGuide Opensource) you can use the PostGIS Provider for FDO (http://trac.osgeo.org/fdo/wiki/FdoPostGISNotes in addition I recommend using the Windows DLLs from http://www.geomapgis.com/web/geomap-group/fdo/index.html). However, this FDO Provider is regarded as beta-quality in every sense (see Open Tickets on Trac page). I've run into many issues with this driver, but have overcome many of these with customized trigger functions that synchronize a second replica table for FDO clients. The nice thing about this effort is that the CAD folks where I work can continue to use familiar software to digitize coordinates, polylines, etc., and the geospatial data are identical in QGIS and AutoCAD displays at all times. I've also used PostGIS for a limited amount of time with Manifold System (http://www.manifold.net/), which has built-in support. However, I've had issues with adding and editing shapes since it commits edits instantly without any ability to fill in attributes before, which usually raises PostgreSQL constraint errors (e.g., I need to assign a unique non-null name to each new feature of a certain layer). With all that said, by far my best PostGIS experience with a desktop app is with QGIS, since it works out of the open source box. I don't need to fabricate any database workarounds for QGIS as I do for FDO, which is of great convenience. The people at my workplace that are using QGIS (starting since 1 month ago) have picked it up quickly, and the value of GIS in the office has gone up quite a bit, since it is no longer exclusive to the few technicians with expensive software. -Mike ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

Hi Cedric I used your code lines and started the debugger. It seems that the QgsMapCanvasSnapper works correctly.

I'm trying to snap a vertex with my python plugin. (Many thanks to Martin for the quick work with the bindings!) My code looks like this: def canvasReleaseEvent(self,event): x = event.pos().x() y = event.pos().y() startingPoint = QPoint(x,y) result = [] excludePoints = [] snapper = QgsMapCanvasSnapper(self.canvas) snapper.snapToCurrentLayer (startingPoint,result,QgsSnapper.SnapToVertex, 1, excludePoints) print result: ,result The problem is, whatever I do, the result keeps empty. I tried to play with tolerance and scale and I'm quite sure it has to find a vertex but without any success (the layer unit is meter). So I thought about using QgsSnapper directly. But I'm not able to set it up properly. Doing the following snippet always leads to a attribut error on the snapLayer struct. snapLayer = QgsSnapper.SnapLayer snapLayer.mLayer = self.iface.mapCanvas().currentLayer() snapLayer.mTolerance = 1000 snapLayer.mSnapTo = QgsSnapper.SnapToVertex So, if anyone has a hint why the QgsMapCanvasSnapper doesn't want to give me a result or how I set up the struct correctly, it would be wonderful to share it with me :-) Best regards and kudos to all the helping people here on the list!

AW: [Qgis-user] printing with metis?
Hi Marco, If you are curious about the print composer developments, just check out the printing branch: svn co https://svn.osgeo.org/qgis/branches/advanced_printing_branch I'm trying to bring the branch to a stable state until 15. August so it can be tested by interested folks. 25. August is the feature freeze for 1.0 and the latest date for merge. To your suggestions: 2. on mouse over the object may show a tooltip showing the name of the object That's a good idea, I added it to my todo list. Maybe tooltip could also show the most important properties of the object 3. users should be able to resize the objects on the page directly with the mouse (such as resizing windows); now resizing is possible only giving the width-height parameters as numbers (that's good for a fine sizing, but not for a quick one) In printcomposer branch, it is possible to resize the maps in composer and also to move the content of composer map. For the other objects (scale bar, label, legend), resizing changes the size of the frame, but not the size of the content. 1. when the user press an add object button, the object may be automatically placed on the map, with a standard (small) dimension and position (left up corner?) I'm not sure about that. Most graphic programs (and also the main window of QGIS for some tools) work the way that a user picks a tool and nothing happens until mouse click or drag in canvas is done. E.g. in inkscape, if you add a rectangle, you pick the rectangle tool and the rectangle appears once the user drags the mouse on the canvas. I think it is quite natural to work this way. However, in inkscape, there is a changing mouse cursor depending on the selected tool. I think that would also be helpful in the print composer.

Hi Tim,
Marco what is the plan / status of that for 1.0?
Prior 1.0, there will be no major redesign of vector rendering mechanism. Post
1.0, I think it is absolutely necessary to do so and to let renderer subclasses
decide what shapes to draw.
I think the patch only makes sense if, as you suggested in February (see
below), the arrow heads can be enabled/disabled via vector layer props and the
state is saved to the project file.
If anyone vigorously disagrees let me know,
otherwise I'll incorporate your patch in 0.9.3 with some additions
from myself to enabled or disable line arrows via the layer props
dialog, the vector api and the layer properties serialisation
mechanism.

draw_start_and_stop draws a green dot at the start and a red dot at the

AW: [Qgis-user] Unable to open databases
Hi Carlos,
I had a similar problem recently and it was ok after I did a make clean or a
fresh svn checkout (svn update was not enough).
Don't know if your problem is the same or a different one.
Regards,
Marco

Betreff: [Qgis-user] Unable to open databases
I have recently lost connection to srs.db and also (I think) qgis.db
databases, so I get different errors and problems running both 0.10.0
and trunk versions ('Critical: Can't open database: unable to open
database file' and similar). I don't really know where the problem comes
from, but I think it can be related with sqlite packages in my system.
I've tried reinstalling/updating sqlite, but the problem is still there.
Any idea?
Regards
Carlos

AW: [Qgis-user] why is EPSG:2180 not recognised?
Hi Maciej, Jean-Claude Please don't tell me that I can send a patch with updates for the CS database. That would fix only my problem, while EPSG database has lots of fixes and additions in each new version, which get included in new releases of PROJ, GDAL, GRASS but not in QGIS. It is of course also possible that you update the other entries in the sqlite database of qgis. Ideal would be a volunteer that acts as a maintainer of srs.db and updates it in regular periods.
