Bug report #16483

Updated by Giovanni Manghi about 7 years ago

when loading in a delimited file with WKT geometry of type MultiPoint, geometries are invalid if all longitude values are negative. QGIS 2.18.3.

code samples here on gis stack exchange : https://gis.stackexchange.com/a/238583/55203

this seems to be restricted to the delimited text provider; it works fine with shapefiles and geoJSON. If I split the multipoints into distinct point geometries, or use linestrings, it works.

It doesn't seem related to line length (truncation), geometry direction or the dateline issue (values of +/-180 or +/-90 for longitude and latitude).

I've also tried shuffling the points at random, applying jitter (to rule out issues with mixed int/float parsing).

It seems to be an import issue, not a rendering/projection issue.
