The issue is in choosing an external format for LINE which does not lose precision during dump/reload. Internally, LINE is described by a formula which is likely subject to problems with limited precision for some line orientations. Does anyone have a suggestion (perhaps drawn from another GIS package) for representing lines? We already have this implemented internally, and the algorithms are used to support other data types; the only unresolved issue is in how to input the values. - Thomas ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/users-lounge/docs/faq.html
