i am working on some camera data. I have some points which consist of azimuth, angle, distance, and of course coordinate field attributes. In arcmap I want to draw shapes like this:
The shape is pink. Can I get the shape with postgres-postgis? Thanks. |

There is a 2009 ArcGIS python script here: http://arcscripts.esri.com/details.asp?dbid=16089 If you have the necessary attributes in your point feature class, then it is pretty straightforward and the script creates a polygon feature class. You need a From azimuth and To azimuth so you might need to do some calcs on your table first. It also uses a From distance and To distance, but from your diagram you probably want those two fields to be equal for each point. The script creates a polygon for each point. It doesn't have a smooth arc but the script creates polygon edges at 1 degree increments, so it's pretty good. |

ESRI just added a blog post and ArcGIS 10 tool for this problem here: http://blogs.esri.com/Support/blogs/mappingcenter/archive/2012/02/15/pie-sector-features-communicate-multivariate-data.aspx |
