I'm trying to run the following test CSV through the Delimited Text plugin as WKT data:

oid,Line
1,LINESTRING((45.554194 -122.686101, 45.433001 -122.762632))
2,LINESTRING((45.432505 -122.598327, 45.423743 -122.592932))
3,LINESTRING((45.285959 -122.333998, 45.423743 -122.592932))
4,LINESTRING((45.548994 -122.514218, 45.519204 -122.679675))
5,LINESTRING((45.491189 -122.873493, 45.433001 -122.762632))
6,LINESTRING((45.380535 -122.743911, 45.397011 -122.79874))
7,LINESTRING((45.347019 -122.350363, 45.423743 -122.592932))
8,LINESTRING((45.582386 -122.689115, 45.536485 -122.65859))
9,LINESTRING((45.430841 -122.782667, 45.380535 -122.743911))

All I'm getting for my trouble is this error:

The layer file:///$PATHTOFILE?delimiter=%5B,%5D&delimiterType=regexp&wktField=Line is not a valid layer and can not be added to the map

I have to be missing something simple here, but I have no idea what it is, and Google hasn't been helpful. I'm using QGIS 1.8.0-Lisboa.

  • csetzkorn: you are correct, it should be LINESTRING(long lat, long lat) I just confirmed it as I worked through some points in QGIS2.12.2-Lyon Using Lat and Long will create the lines to a different region than your existing shapes. – Resedu Mar 3 '16 at 17:43

There are two possibilities here (see http://en.wikipedia.org/wiki/Well-known_text for more possibilities):

  1. LineString - LINESTRING (30 10, 10 30, 40 40)
  2. MultiLineString - MULTILINESTRING ((10 10, 20 20, 10 40), (40 40, 30 30, 40 20, 30 10))

Currently you have LINESTRING and (( which is wrong.

UPDATE There is also a problem with the commas as Jason says, I managed to get the following to import (once I changed the delimiter to ;):

oid;Line
1;LINESTRING(45.554194 -122.686101, 45.433001 -122.762632)
2;LINESTRING(45.432505 -122.598327, 45.423743 -122.592932)
3;LINESTRING(45.285959 -122.333998, 45.423743 -122.592932)
4;LINESTRING(45.548994 -122.514218, 45.519204 -122.679675)
5;LINESTRING(45.491189 -122.873493, 45.433001 -122.762632)
6;LINESTRING(45.380535 -122.743911, 45.397011 -122.79874)
7;LINESTRING(45.347019 -122.350363, 45.423743 -122.592932)
8;LINESTRING(45.582386 -122.689115, 45.536485 -122.65859)
9;LINESTRING(45.430841 -122.782667, 45.380535 -122.743911)

    Also, won't those commas in the LINESTRING trip it up and split it into multiple columns? Shouldn't the WKT be quoted? – Jason Scheirer Sep 27 '12 at 9:47
  • Make sure you view the file in a text editor, not a spreadsheet program. I use Notepad++ to Replace All and I remove the " s – Willy Sep 27 '12 at 20:36
  • The (( was an artifact from some other things I tried. I think the main issue I was having is indeed the commas. Thanks! – Pliny Oct 1 '12 at 17:31

    Is the order of lats/longs not wrong here? – cs0815 Dec 14 '15 at 10:32
  • that is definitely lat/long :-) – Ian Turton♦ Dec 14 '15 at 10:33
