Re: [postgis-users] importing curved polygons

Hi Rich, What GDAL/OGR version do you have? Which driver do you use? There are two. According to http://www.gdal.org/drv_openfilegdb.html and http://www.gdal.org/drv_filegdb.html (requires ESRI FileGDB API SDK) both versions require version 2.2 or higher. It is quite likely that you use an

Hi Simon, Thank you. Strk already helped me. I was actually looking for ST_ForceCurve(), which is forcing my geometries into a CompoundCurve geometry, because my target table has a constraint on this geometry type. I don't care too much if the actual geometry is a LineString or a CircularArc

Hi Strk, Yes - ST_ForceCurve() - that's the function I was looking for. Thank you very much! Thanks also for explaining, that ST_LineToCurve() falls back to LineString if it can't generate a curve. Andreas On 2016-10-07 11:28, Sandro Santilli wrote: > On Fri, Oct 07, 2016 at 09:12:18AM

Hi Strk, Yes - I will try that next - loading it in chunks. But wouldn't it miss out on some of the neighbourpolygons then if I use such subsets based on pkey? Thanks, Andreas On 2016-07-13 12:55, Sandro Santilli wrote: > On Tue, Jul 12, 2016 at 01:15:41PM +0200, Neumann, Andreas wr

Hi Strk, Thank you for these hints. It will help me to get started - also combined with your blog entries on the topic! Andreas On 2016-07-01 10:29, Sandro Santilli wrote: > On Thu, Jun 30, 2016 at 11:25:22AM +0200, Neumann, Andreas wrote: > >> Is there a method in Postg
