My day job is Information Security for The University of Auckland, New Zealand.

I have been working in IT for around 35 years. My degree was in science with a heavy emphasis on Mathematics (particularly statistical and computational).

First job was as a statistician in University Zoology Dept after a few years I moved to what was then the "Computer Centre" where I was mostly involved with user support for statistical packages.

Over the years I have done worked in most non management areas in academic IT -- for the last 15 years I have been largely responsible for the technical side of Information Security at tht University.

My specific interest in GIS is centered around my conservation work on Tiritiri Matangi Island www.tiritirimatangi.org.nz where I am the volunteer coordinator for the weeding program.

We initially set up a GIS system of our own to keep track of weed related data but this has mushroomed and now has lots of other stuff as well; )

Thanks Llaves! yes, I tried that first ;) I will play with it a bit more and if I can't get it to work I will file a bug report. It might be a Mac/Maverick issue.

That sort of works! I sent the map to the back and one of the two overlays was exposed but the other was not. Bug?

comment How ensure data put into PostGIS gets proper CRS attached?
I am using a Mac and PostGIS plugin for pgAdmin appears to be Windows only. You can do the same thing with the qgis database manager Import options which is how I am now importing stuff to PostGIS rather than using SPIT.

comment How ensure data put into PostGIS gets proper CRS attached?
I have finally tracked down how I got the data into PostGIS with no CRS attached. I was importing the data from shape file using the SPIT plugin and leaving the "Use Default SRID" in the belief that it would use the SRID from the shape file. I just tried importing a shape file first relying on the "Default" and again specifying the SRID. The one imported with "default" had no SRID associated with it unlike the one where I had explicitly gave it the SRID. I have no idea if this is a bug or a feature ;)

Ironically it was the CSV data that had a CRS attached (I set it on import) the data I imported from the GPS via GPS Tool, save as Shape file then load into PostGIS with SPIT did not have a CRS associated with it. When I created a layer from this data I was always prompted for the CRS. I agree that there was a bug in my data import procedures but it was with the GPS data.

comment Why are some points in my PostGIS layer not displayed?
I tried converting all points in the table to 4326 using ST_TRANSFORM but got the error that there was no CRS associated with the first row. I believe that this is the key. I at one stage while dumping out the geometry of the points I noticed that the new points were tagged with the CRS but not the original one. My bad for not including this before. I should have included the column headings. I have now managed to transform everything to 4326 and data displays correctly so Andre gets bonus.

I tried editing the csv file to add .0 to all the coordinates and reloading it but the problem persists :( but I think I how why. The numbers in the csv file are CRS 2193 which are inherently integer so they may well be converted to by the import process.

Firstly thanks for all the reports. It is starting to look as if it is something specific to my set up which is a Mac mini running Maverick (and yes I know that qgis is not officially supported on maverick).
