Re: [Qgis-user] How set real origin on a false origin dataset

2019-11-17 Thread Lens Paul
Hi Andrea, False origins happens often with local topographical surveys, with also a false altitude origin. Architectural plans are sometimes even more tricky: rotated, or with a centimetric or millimetric scale instead of a metric scale. A way is to transform the data with a CAD software when

Re: [Qgis-user] problem with dxf2shp

2015-06-26 Thread Lens Paul
Hi Daniel, I have not made that kind of conversion for a while now, probably back to QGIS 1.5. At that time, dxf2shp didn't keep any 3D information indeed. - v.in.dxf in GRASS worked well; - if you have a raster, extracting contours with the QGIS interpolate command was succesfull too (a

Re: [Qgis-user] Extract 3d attribute information

2015-05-31 Thread Lens Paul
Hi, Christof! I didn't practice 3D for a while and I'm not a geek either. QGIS does not explicitely treat vectorial 3D information, but some (many?) tools treat the vectors without losing Z values. Besides, QGIS evolves so fast that it is difficult to keep track of the way it handles z

[Qgis-user] QGIS and Antivirus software?

2014-05-09 Thread Lens Paul
Does anyone experience problems with antivirus software. In my case, QGIS (1.8 than 2.2) hangs after loading several layers of a rather big project (backups and similar projects won't open either). The processor works at 100% and the whole system almost freezes. I tested load time of

Hello Lester, I tried converting a 3D point shapefile using save layer as + GEOMETRY=AS_XYZ (still using QGIS 1.8). It didn't work but I do not have much time to try again. Joined to this mail, you'll find a table with some information about the conversion of 3D GIS/CAD Data. It's a rough

Re: [Qgis-user] nodata color in rasters

2014-03-10 Thread Lens Paul
Nodata has a value: you can use a custom palette and asign a colour to that value. I suppose the Nodata value is the value automatically set as transparent under the tab Transparency in the raster's Layer Properties. In my case, this value is: -3.40282e+38. (other possible values? 255,
