Re: [postgis-users] Dumping out points in a linestring
Thanks Nicolas. I was wondering what these points in the linestring symbolize? Are the default set of points on a 2D linestring indicating the positions at which the line is not straight and changes directions?

Re: [postgis-users] Error adding raster support
Hi Bborie, sorry for the belated response I haven't been at the office the past few weeks. As you suspected something is wrong with gdal: $ gdalinfo gdalinfo: error while loading shared libraries: libodbc.so.1: cannot open shared object file: No such file or directory $ gdal_translate gdal_translate: error while loading shared libraries: libodbc.so.1: cannot open shared object file: No such file or directory I'll have to sort this out before I get back to PostGIS. Any suggestions on how to do it are welcome.

[postgis-users] What have I got wrong?
Hi all, Apologies to everyone if this has already been documented before or if my problem is so obvious but.. After trying for the best part of three days I'm unable (unsure what the heck I'm doing wrong) with trying to get postgis working with postgres. If anyone can point out what it is I be hugely grateful. I've followed the official postgis installation documentation and guides / tutorials on the PostGIS WIKI and keep arriving at the same message below in a terminal window. createdb: could not connect to database postgres: could not connect to server: No such file or directoryIs the server running locally and accepting connections on Unix domain socket /tmp/.s.PGSQL.5433? If it helps I'm running Ubuntu 12.04 LTS and have been trying to bring things to life with Postgres 9.1 and PostGIS 2.0.1 Thanks in advance for any support.

Re: [postgis-users] What have I got wrong?
Specifically, did you try createdb -p 5433 ? I'm not a Ubuntu specialist, but is it possible you already have a stock postgresql running on port 5432 and that the 9.1 version took the 5433 port to run on ?

[postgis-users] St_Area to acres

It seems that I am almost there, but I am a decimal off and I can't understand that. Also I am not very familiar with the 26986, but I used it because I saw it used for sqare feet somewhere else.
