SpatiaLite 2.2 Release Update
In light of some recent comments on this blog about the direction TerraGo is heading with its product line, I thought it would only be fitting to announce the latest release of SpatiaLite. I have posted about SpatiaLite before and it was very well received which makes it apparent that this is a highly desirable database technology in our industry.
2.2 is the current stable release supporting:
- full UTF-8 SQLite internal data storage and locale charsets for input and output
- a GUI tool supporting DB management in an user friendly way
- PROJ.4 latest version (4.6.1), this including an updated EPSG dataset
- SQLite's latest version (3.6.2) implementing the definitive R*Tree Spatial Index
- an alternative Spatial Index implementation using MBR caching
- added the new Virtual Table module VirtualText supporting direct SQL access to CSV and TxtTab files
There is a Google Group that has been been created to use for public support and announcements related to this project. You can find this group here and I encourage everyone to participate...
What can this technology do for you? We've seen basic attribute queries in other software applications but imagine taking enterprise-level spatial query capabilities to your desktop in a completely redistributable package (aka. single GeoPDF). Given the nature of the SQLite engine, the data publisher (YOU!) will be able to package multi-source data layers in a single file and then import/export as needed.
Thanks again to Alessandro for continuing development on the SpatiaLite project...
