Hi,

I've encountered a problem when using a GeometryReplacer With LineStringZ

Invalid WKT encountered: LINESTRINGZ(541502.5560000000 152585.6960000000 583.544, 541502.4660000000 152585.4560000000 583.775, 541501.2901908699 152581.1464218800 0.0)

I do assume that LinestringZ is not an OGC WKT recognized format yet, although it is recognized as a valid OGC WKB format.

http://portal.opengeospatial.org/files/?artifact_id=25355

My goal is to check the geometry validity from my linestringz features before sending these to my postgis database.

SELECT ST_ISVALID(ST_GeomFromText('LINESTRINGZ(541502.5560000000 152585.6960000000 583.544, 541502.4660000000 152585.4560000000 583.775, 541501.2901908699 152581.1464218800 0.0)'))

Any idea how I could deal with this on FME 2018?

Or, "LINESTRING Z" (insert a space before 'Z') should work. See the section 7.2.3 BNF Productions for Three-Dimension Geometry WKT, page LV in the specification you have linked.

It seems FME doesn't like the "LINESTRINGZ" moniker. You can use a StringReplacer to replace it with simply "LINESTRING" and it'll work.

Why not inspect features with Visual/Data Preview and Feature/Record Information before writing them into a destination dataset?

Funny how all the odd numbered pages seem to be numbered using Roman numerals :-)
