Recently I was asked to review a database migration from one vendor’s database to another’s. The conversion involved geospatial data and database internal representations.

Yesterday, Tuesday 20th January 2009, I gave a flawed, imperfect, rather long talk called Free And Open GeoData – From Shadows to Reality at the March South Together, linux.conf.au 2009 Conference at the University of Tasmania. If one wants to get a message across, and perhaps be entertaining, one has to sprinkle one’s talk withRead More

My two papers were: Automated Layer Management – Experiences At Mid Coast Water Gridding vs Simplification in Extracting Performance from High Density Data The first was co-authored with Mr Brendan Soustal thoughRead More
This article has been a long time in gestation. Sure, I could have written it anytime in the past 12 months, but it is just has not been in my top 10 jobs: paid work always takes preference to “labours of love” The ESRI value-add conundrum For anyone selling software in the GIS industry oneRead More
