Fooling around with QGIS (v 2.18) global program-settings, I found some interesting setting. It allows the user to copy geo-features directly from the table to the clipboard as GeoJSON (geom + attributes). So, no “export to…” etc. is needed.
Many different organisations have to deal with the management of guideposts – especially in alpine regions. Sometimes all the data about the guideposts is managed in databases and GIS-Systems.
