I have only four fields in the GPX file which I want to keep (lat, lon, time, name).Then I have an empty template shapefile, which has more fields defined. Some of them has to be filled interactively in QGIS, some of them will be filled by trigger functions in PostGIS. The point is that the template shapefile has to match exactly the table definitions in my PostGIS database, so that it is possible to append GPS datasets to the database using PostGIS Manager plugin. I can't just spit the GPX files straight to PostGIS. The problem is how to "combine" the GPX points with the template. I've tried to merge these two with fTools and mmqgis plugins, but these both add all fields from both layers, which I don't want (there isn't an option to choose fields). Also I haven't found any "append" tool similar to ArcGIS in QGIS. I know it's possible to overcome this with manually deleting the unwanted fields, but I want to automate the process since this part will be repeated hundreds of times. Any ideas? Can you skip the shapefile step altogether and use ogr2ogr to go straight from gpx to PostGIS ? ogr2ogr has an -append option to add new features to an existing layer, and a -select option to list which fields you want to insert into the target layer. Then, with the new features already in PostGIS do your interactive editing as needed from QGIS.
