Works brilliantly, thanks again. - Set env var: export OGR_WKT_PRECISION=4
- In Python interpreter: from osgeo import ogr datasource = ogr.Open('World_Admin_2.shp') layer = datasource.GetLayer(0) feat = layer.GetNextFeature() geom = feat.geometry() wkt = geom.ExportToWkt() was: 151.857685024000034 -32.613605699642989,151.857672992 -32.613692002142983)) now: 151.8577 -32.6136,151.8577 -32.6137)) Roger --- On Tue, Aug 16, 2011 at 10:53 PM, Roger André <ran...@gmail.com> wrote: > Thanks Chaitanya, > > I like the look of that second option.
