I have several files in WKT format, and something strange happens when I import them in QGIS (v.2.18.1) (layer->add layer->add delimited Text Layer), files containing lines and polygons are correctly located on the map, but those containing points are not, and the same CRS is used (EPSG: 4326, WGS84) for all files.

Lines and Polygons are located here, all OK

The examples that I put correspond to data an area of the north of Spain, and as you can verify, the lines and points are loaded in that zone, but the points go to the Indian Ocean, in the coast of Tanzania.

Points are bad located

Here you can download the wkt files used (are only 65KB zip file) : https://drive.google.com/open?id=0B2tCGwcrrXRtN2tHSldfbDJ6MlE

It is very strange, because the coordinates are good, if I take a point of the file that is misplaced, and I copy the coordinates within google maps, the point is correctly located in the north of Spain.

Here I put some lines (only the first ones) with the content of these files (utf-8).

  • Very odd. They should all be in the wrong place because in WKT coordinates are supposed to be in longitude-latitude order. – user30184 Dec 12 '16 at 9:44

Your point layer coordinates are flipped. The template for WKT is (x,y), where as Geographic coordinates are (y,x) = (lat,lon).

Alas, your Line and Polygon features are corrupted as well. The comma separating coordinate pairs appear after one value, not a pair, thus the 1st and last vertices are misplaced.

Correct point (albeit flipped) appears as Point(XY):

0x6510|Océano Atlántico|POINT(43.71632 -8.14070)

Incorrect Lines, note the comma between odd pairs, appears as Line(X,YX,YX,..,Y):

0x15||LINESTRING(43.69263,-8.05847 43.68713,-8.06396 43.68164,-8.05847 43.68164,-8.06946 43.67615,-8.06396)

  • Many thanks, Dun, I imported my data from an old map in format 'polish format' from garmin and in that format the latitude and longitude were in reverse order, hence my error. – Juanma Font Dec 12 '16 at 12:14
