Ask Slashdot: Open Source vs Proprietary GIS Solution?

New submitter rnmartinez writes "As the Project Manager for a non-profit looking to implement a tech project, I am running into a few dilemmas, and as a casual Slashdotter I could really use some help. I'll start with a brief explanation of the project. We research issues in Canadian Immigrants, and found that there was a lack of recent, unaggregated information. As we dug further, we found that some data was available, but there was no central repository. Therefore, we are building a web based service to collect this data, with the intent of having it display in Google Maps and then be downloadable as a CSV file that is readable in GIS software such as ESRI Arcsoft, so that data may be visualized." The dilemma: "...It seems that MS SQL offers more functions with regards to geometry built in then MySQL, and my developers (good guys, but MS guys at heart) want me to switch to .net NUKE/MSSQL and ditch the open source stuff." Read on for further details.

"To date, we have relied on a LAMP box with Drupal as the frontend to help provide a more social experience. However, it seems that MS SQL offers more functions with regards to geometry built in then MySQL, and my developers (good guys, but MS guys at heart) want me to switch to .net NUKE/MSSQL and ditch the open source stuff. As a believer in open source and as a non-profit, I am having some moral issues with this (I try and run Linux and open source on everything I reasonably can)."

"So here is my dilemma: do I dump $20K into moving everything to an MS solution that in the short-medium term might make the geometry functions (i.e. show me all the hospitals within a 20km radius of this cluster of immigrants) or do I get him to spend the same amount writing something similar for MySQL? The only issue there, is that I am not too fond of Oracle having ownership of MySQL. Should I be directing $20K into replicating these functions into something like MariaDB? Might be a longshot but again, as a non-profit I'd like to see something go back to everyone, not just my group."

"Really, I am open to any flexible, creative open and reliable solutions. Sorry if my knowledge is limited or if I am grasping at straws, and if I am being terribly biased, but I trust Oracle with open source about as much as I trust MS."

MySQL might fare poorly against MSSQL's geometry support, but how does PostgreGIS stack up?
