Hi there everybody, I want to derive some floating point values using an expression in the field calculator (see model snapshot below).  I'm using qgis 3.10.6 on Debian 10. I am finding that the first field calculator call, which produces 'dbgfieldcalc', gives only NULL answers. The second

Hello, QGIS 3.x provides a complete interface to manage the metadata of a project, but the metadata are saved in a "qmd" file while I need metadata in "xml" format. Is there any way to turn a .qmd file into a .xml file? Thanks ___ Qgis-user mailing list

This is a task archaeologists often have to do with hundreds of digital images of our precious sites. The starting point is to have geographic data in your image. Typically with a tablet this would be through a GPS location from your internal GPS which is subject to all the limitations on hand

[Qgis-user] Developing a directed graph

Re: [Qgis-user] Taken photo windows tablet

Hi Guayente, there is a QGIS plugin 'ImportPhotos' that works fine. If you put all your photos that should be enclosed in a layer for QGIS, in one folder, the plugin will create a point layer with the recorded coordinates according the geo taggings of the photos. The resulting layer will be a

Re: [Qgis-user] How to determine the inner surface on a sphere or ellipsoid

Hi Nyall, Just out of curiosity, would a very large polygon slow down a spatial query or would just a complex one? My testing with using shapefiles to reclassify LiDAR data did show that things could be sped up by splitting large polygons with a smaller grid but I had attributed this to the

Hi, If your photos are geotagged, then you can used the geotagged to get the position. Look in the plugins for photo or geotags. You should find something there. Nicolas Cadieux Ça va bien aller! > Le 17 juin 2020 à 02:31, Guayente Corral a écrit : > >  > Hi, > Is there a good way to

Hello, I am just wondering if the ability to import a GeoPDF is or will be available for macOS. I noticed some people are able to import a GeoPDF into QGIS as Raster or Vector, but I have never had the pleasure on mac. I presume due to the lack of GDAL PDF libraries built for mac. Thank you,
