18.104.22.168. Table manager plugin
New attribute fields can be added or deleted directly within the Attribute table or the Field calculator dialog. But at this stage there is no option to rename any given field. For all changes within the table structure (adding, renaming and removing operations), the Table manager plugin is the perfect tool. As this is an optional plugin, it has to be downloaded first from the Official QGIS Repository (see section 7.1.3.). In this example, we rename the geometry columns:
- Go to Plugins.
- Select Table.
- Select Table Manager (the edit mode has to be turned off).
- Locate the field in the list called “XCOORD”.
- Click the Rename button and rename it as “longitude”.
- Click OK.
- Do the same with “YCOORD” renaming it as “latitude”.
- Confirm the changes by the button Save.
- If changes are made for fields used for layer styling or labelling, some features may become invisible. This should not be the case in this example.
- Click Yes
to keep the current layer style.
The Table Manager is very strict in terms of the length of field names and the characters allowed. Due to this, it may be difficult to find suitable field descriptions, but this is the price to pay for preserving interoperability options between different file formats.
- Save the layer to a new shapefile into the CRS CH1903/LV03 (see section 7.4.4., e.g. with the name bees_colony_locations_coordinates.shp)
- Import this new shapefile (e.g. and add geometry columns again, see section 22.214.171.124.)
- Open its Attribute table.
- Compare the different columns.
Now the coordinates of the points are listed as attributes in the two CRS, one in degrees (WGS84) and one in meters (CH1903/LV03).
