3.2.8. Importing data

It is quite easy to import data (geometry and attributes) from an external software. Here is a general description and a specific example.

3.2.8.1. General

• You have to add the data you want to import as (vector) layer into the QGEP project.

• The field names of the attributes have to be the same as the field names of the QGEP Layer. Therefore it is normally not a good idea the use shp-files, because of the 10 letters limitation of the dbf-format (Alias field names do not work).

• If you have a translated project, be sure to take the English field names (not the translated name that you find as Alias of the field).

• If there is a field with value list, you have to use the code, not the plain text.

• If your fields are prepared as described above, then just copy and paste in the QGEP-layer.

3.2.8.2. Example Importing manholes from a TXT-File:

• Change the field names to identifier, x, y, co_level

• Open the txt-file with Layer ‣ Add Layer ‣ Add Delimited Text Layer….

• You have now a vector-layer with your points in the QGEP-project

• Select the points of the new layer

• Choose Edit ‣ Copy Features.

• Select the vw_qgep_wastewater_structure layer and set it editable

• Choose Edit ‣ Paste Features.

Notă

The ws_type is set as default to manhole. The identifier is used not only for the wastewater_structure, but also as cover_identifier and as wastewaternode_identifier.

3.2.8.3. Example Importing manholes with attributes:

• Example to add additional attributes

• The field ws_type is an exception. Possible values are manhole, special_structure, infiltration_installation, discharge_point.

• For other fields with value lists you have to use the code.

• In the example above, the values for ma_function in the row discharge_point or special_structure has no effect.
