I already have the exact points for the CIRCULARSTRING, so I don't want it approximating anything. | |

| Nov 10, 2011 at 23:42 | comment | added | EM0 | You're right, I should have put in an example. Edited the question to include it. | |

| Nov 10, 2011 at 15:21 | comment | added | CaptDragon | Sorry, now i'm confused. Your questions says you want to get a CIRCULARSTRING from points and now your saying you want to get a LINESTRING (a group of points) from CIRCULARSTRING using ST_CurveToLine. FYI: People are reluctant to answer questions that do not provide examples of inputs or desired outputs. Please provide an example of data you are working with and what you expect so your question becomes clear and people can test the data and answer your question with confidence. I'm just telling you because i know you're new here and i would like to see your questions answered. | |
| Nov 10, 2011 at 4:16 | comment | added | EM0 | Thanks, but that won't work in my case, because I don't have the line that's a close approximation of the curve. I only have the 3 points that CIRCULARSTRING takes. In fact, after I create a CIRCULARSTRING I'm going to convert it to a LINESTRING using ST_CurveToLine. | |
