Well. Manifold has taken its sweet time with its release schedule. I think that the last new product they published was in 2011, then went silent. This last week they released Radian Studio after a year of beta testing. They call the product a spatial engineering tool not a GIS, and this is true. The best way to understand the uses and purpose of the product is to read their FAQ.
Some highlights of the product. If you do not want to read their FAQ
If you want to be at the cutting edge of GIS software and are ready to learn RDBMS programming and tools by all means try Radian Studio. If you use Manifold 8 GIS or any other GIS package, and are not planning to use an RDBMS as your GIS data storage strategy or do not need more speed. I suggest that you wait for Manifold 9.
My next post will be about how Radian Studio will change my life (for good or bad)
