Existing open source tools and possibilities for cadastre systems
Pieper, Gertrude
When it comes to computer software, the old saying you get what you pay forr may no longer apply. After years of skepticism towards open source software, many of todayys open source solutions are as good, if not better than proprietary software solutions. The question iswhy is it then that there are so few land administration systems making use of open source software technology? Lack of knowledge about the possibilities might be one of the reasons. After all, marketing has never been a priority for developers of open source software. Doubts about the security and available software support could further shy away cadastre agencies from making the switch. The FAO-FIG publication on FLOSS in Cadastre and Land Registration Opportunities and Risks looks into these issues. Chapter 3, section 1 of the publication intends to give an overview of available open source database and GIS tools that are useful for cadastre systems. First, cadastre systems and their software requirements are analyzed, and then an overview is given of open source alternatives. The core of digital cadastre systems generally consists of a data repository containing cadastral boundaries and land register data. When comparing open source database products PostgreSQL and MySQL it is found that both are excellent database tools, but PostgreSQL with PostGIS has better spatial functionality than MySQL.
