#2888 closed defect (invalid)

ogr2ogr conversion with EPSG:28992 not correctly

Reported by: oxygen Owned by: warmerdam
Priority: high Milestone:
Component: Utilities Version: unspecified
Severity: major Keywords: FWTools (win) 2.2.8


Conversion between KML and ESRI shapefile (and back) using EPSG:28992 results in wrong placement.

We used a correct KML (in Google Earth / Maps) converted it into ESRI shape, read it in Quantum GIS with a Dutch WMS server We used a correct ESRI Shapefile converted into KML and viewed it in Google Earth.

Displacement is approx. 67 meter.

Seems to be a proj4 related issue or use issue... I see that the proj4 definition for EPSG:28992 use the Bessel ellipsoid, but does not specify a datum. So as you use PROJ4.6 or later (FWTools 2.2.8 ships with 4.6.1), no ellipsoid to ellipsoid will be made. My guess would be that it is exactly the issue discussed in

Given Even's analysis this is not a GDAL problem. It is a user coordinate system specification issue.

I would add it is also not a PROJ.4 problem so don't file a ticket there unless it is one providing a compelling case to override the datum definition associated with EPSG:28992 with a particular towgs84 solution with lots of supporting information on why that is the right single choice for everyone in the world.
