I have received some shapefiles which I believe are from ArcGIS. Each "file" consists of a number of physical files, e.g.

kv_27.dbf
kv_27.shp
kv_27.shp.xml
kv_27.shx

I need to extract the coordinates from these files. I am trying to use QGIS and the instructions here:

How to get Shapefile point coordinates into .xls?

I am opening the files using Add layer >> Add vector layer

My first question is which file or files should I open?

When I try to carry out the command

Vector >> Geometry tools >> Add/Export Geometry Columns

Once I click OK I get the error message:

Currently QGIS doesn't allow simultaneous access from different threads to the same datasource. Make sure your layer's attribute tables are closed. Continue?

Neither option (yes/no) provides the coordinates.

Could someone explain what it is I am doing wrong?

  • You should add the .shp file. The warning is not an error message, just continue. – AndreJ Jun 22 '16 at 17:38
  • @Vince - With Iant's help I have exported the attribute table but all that is included is ident area PERIMETER : 27 459078.1223 3921.444532

    I believe this means the attempt to add the coordinates has failed? Correct?

You could use the save as option and select csv as the output format.

Not sure this strictly answers the original question but it has resolved my problem which was to extract the coordinates into a file I could use.

Firstly I did as suggested and opened the .shp file as a vector layer (Add layer >> Add vector layer)

Then I enabled the MMQGIS plugin

Finally I selected MMQGIS >>Import/Export >>Geometry Export to CSV File

This produces two files 1) an attribute file 2) a nodes file

The nodes file contains the coordinates for the shape

Thanks for everyone's help.
