Mini-tutorial about using the spatial extensions in MySQL 5.0
While helping a user with some questions about the geospatial extensions of MySQL on the #mysql-dev IRC channel on Freenode, I stumbled over this blog: How to use MySQL Spatial Extensions. There currently is just one post, but it was exactly what we were looking for: "Using Circular Area Selection". Nice work! I hope the author will soon provide more examples of how to make use of this functionality.
By the way, there is work in progress to improve the GIS functionality in MySQL - if you are looking for new GIS functions that do not use MBRs, take a look at our GIS feature preview on the MySQL Forge. We plan to publish a new set of preview binaries once the 5.1.23 release has been published and merged into this code base.
