[Qgis-user] proj: NTv2 for Baden-Württemberg

Hi there, in Germany, two further states are currently switching to UTM32 (Bavaria and Baden-Württemberg). Both have published the NTv2 files as OpenData. Since I had a set of GK3 coordinates (EPSG:31467) from Baden-Würtemberg, I checked if the new version 5.0.1 of "proj" can process the data

[Qgis-user] proj on Windows: mini howto for Cygwin

Hi there, since "proj" uses OSGeo4W to release Windows builds, some users are disappointed since OSGeo4W hasn't updated this library for quote a while. Since I wanted to do some tests with latest proj, I had to compile it for myself. Perhaps you're interested in the steps needed. I've used a

[Qgis-user] Convert CSV to legend

Re: [Qgis-user] Road network download

For instance, you can use the field calculator to clean some values in the 'oneway' column. You can also display an arrow on the line if the field oneway=yes 2018-05-04 15:22 GMT-04:00 Xristos Xristoou : > Thank you! How to do that ? Pre processing? > > > Στις Παρ, 4 Μαΐ 2018

Re: [Qgis-user] Road network download

Values are written in the link I put about -1, 1, yes. Often, with OSM data, you need some pre-processing to clean all these values. It's based on the direction of the line. Maybe shapefiles from geofabrik are cleaner? 2018-05-04 13:24 GMT-04:00 Xristos Xristoou : > I have

Re: [Qgis-user] Road network download

Re: [Qgis-user] Raster calculator questions

Hi, I am not sure of what you mean in the first part of the question but yes, you must create the output file to receive the output from the calculator. As for the second part, QGIS currently has a big limitation with the raster calculator. I have been trying to get them to work on this for

Dear Friends QGIS 3.4 is coming in October this year. Our little metadata group we did excellent work getting the foundations for a great metadata system implemented in QGIS 3.0. Now we are starting thinking about the next phase. I would like to initiate a call (or text chat meeting in Gitter)
